This chapter describes fabric card, line card, and CPT 50 panel.

Introduction to Carrier Packet Transport Cards

This topic describes the Carrier Packet Transport (CPT) cards. There are two cards in the CPT system:

  • Fabric Card
  • Line Card

The CPT 50 panel is a standalone unit and can be connected to the CPT system. The CPT 50 panel enables the number of ports to be scaled on the CPT system.

These cards are supported on the CPT 200 and CPT 600 platforms. The CPT system complies with RoHS-6 standards.

The following system configuration is recommended on the CPT 200 shelf:

  • Standalone fabric card
  • Standalone TNC/TSC card
  • One or more CPT 50 panels

The following system configuration is recommended on the CPT 600 shelf:

  • Redundant fabric cards
  • One line card
  • Redundant TNC/TSC cards
  • One or more CPT 50 panels

Fabric Card

(CPT 200 and CPT 600 only)

The fabric card is a single slot card with two 10GE SFP+ ports and two 10GE XFP ports. The XFP ports on the fabric card support the Optical Transport Network (OTN) protocol. The SFP+ ports on the fabric card can serve as normal ports or InterConnect (IC) ports. When the SFP+ ports are used as IC ports, these ports are used to connect with the SFP+ ports on the CPT 50 panel.

The fabric card runs the route processor version of IOS. The fabric card manages the line card and the CPT 50 panel through the backplane GE management channel.

When fabric and line cards are installed on the shelf, a bidirectional 2 * 16G connection is set up between each fabric and line card and also between two fabric cards.

In chassis AC type, two fabric and two line cards are supported. In chassis DC type, there is no limit on the cards that are supported.

Circuit creation is possible only at XFP ports of the fabric card. Only OCHTRAIL creation is supported. Before creating the OCHTRAIL, create a provisionable patchcord (PPC) between the XFP port of the fabric card and the OCH port.

Slot Compatibility

On the CPT 600 shelf, install the redundant fabric cards in slots 4 and 5. There can be up to 2 fabric cards on the CPT 600 shelf. The two fabric cards on the CPT 600 shelf can both be in active mode with both cards carrying the traffic.

On the CPT 200 shelf, install the fabric card in slot 2 or 3.

Card-Level Indicators

Table 1  Card-Level Indicators
Card-Level LED Description

Red FAIL LED

The red FAIL LED indicates that the processor of the card is not ready. This LED is on during the reset. The FAIL LED flashes during the boot process. Replace the card if the red FAIL LED persists.

Green ACT LED

If the ACT LED is green, the card is operational (one or more ports active) and ready to carry the traffic.

Amber SF LED

The amber SF LED indicates that a signal failure or condition such as LOS, LOF, or high BERs is present in one or more of the ports of the card. The amber SF LED is also on if the transmit and receive fibers are incorrectly connected. If the fibers are properly connected and the link is working, the light turns off.

Port-Level Indicators

A port status LED is provided for each SFP+ port and XFP port on the fabric card. The XFP ports on the fabric card have only Link LEDs and no ACT LEDs.

Table 2  Port-Level Indicators
Port-Level LED Description

Link LED

Green—The port is either in–service and receiving a recognized signal (that is, no signal fail), or out–of–service and maintenance (OOS,MT or locked, maintenance) in which case the signal fail and alarms are ignored.

Red—The port is in–service but is receiving a signal fail (LOS).

Amber—The port is provisioned and is in a standby state.

ACT LED

Indicates data reception. The LED blinks on packet flow.

Line Card

(CPT 200 and CPT 600 only)

The line card has four 10GE SFP+ ports. The SFP+ ports on the line card serve as normal ports or InterConnect (IC) ports. When the SFP+ ports are used as IC ports, these ports are used to connect with the SFP+ ports on the CPT 50 panel. The line card runs the line card version of IOS.

When fabric and line cards are installed on the shelf, a bidirectional 2 * 16G connection is set up between each fabric card and each line card and also between two fabric cards.

Slot Compatibility

On the CPT 600 shelf, install the line cards in slots 2, 3, 6, and 7. There can be up to four line cards on the CPT 600 shelf. However, the line card is not required to be present on the CPT 600 shelf.

On the CPT 200 shelf, install the line card in slot 2 or 3. There can be a single line card on the CPT 200 shelf. However, the line card is not required to be present on the CPT 200 shelf.

Line Card States

The line card could be in one of the following states:

  • Empty slot
  • Card pre-provisioned
  • Card plugged-in
  • Image downloading
  • Application initialization
  • Ready

Faceplate

CPT 50 Panel

(CPT 200 and CPT 600 only)

The CPT 50 panel enables the number of ports to be scaled on the CPT system. The CPT 50 panel has 4 10GE SFP+ ports and 44 GE SFP ports. The CPT 50 panel runs the line card version of IOS.


Note

The CPT 50 panel is not placed in the CPT 200 or CPT 600 shelf.

The CPT 50 panel cannot operate independently. After connecting the CPT 50 panel to the fabric card or the line card, the CPT 50 panel is automatically discovered and registered. The discovery operation is performed using the Satellite Discovery Protocol (SDP) and the registration operation is performed using the Satellite Registration Protocol (SRP).

The four SFP+ ports on the CPT 50 panel can be connected to the SFP+ ports on the fabric card or the line card. The four SFP+ ports on the CPT 50 panel can be connected to only one card (fabric or line card) at a time.

CPT 50 shelf supports ONE-GE and FE for 1 to 44 ports. CPT 50 shelf supports TEN-GE for 45 to 48 ports. By default, the 45 to 48 ports are in IC mode and cannot be changed.

The CPT 50 panel has redundant DC feeds. The CPT 50 panel DC power supply can handle 48 V and 24 V. The 48 V power supply has both ANSI and ETSI versions.

The CPT 50 panel has a removable fan tray and a local console port for onsite access and debugging.

Faceplate

There are four variations of the CPT 50 panel faceplate:

  • CPT 50 panel with AC power. See Figure 1.
  • CPT 50 panel with DC ETSI 48 V. See Figure 2.
  • CPT 50 panel with DC ANSI 48 V. See Figure 3.
  • CPT 50 panel with DC ANSI 24 V. See Figure 4.

Card–Level Indicators

Table 3 CPT 50 Panel Card–Level Indicators
Card-Level LED Description
PWR Indicates the status of the power to the card. If there is a power failure, this LED turns red.
FAN Indicates the status of the fan to the card. If there is a fan failure, this LED turns red.
CRIT Indicates the critical alarms in the network at the local terminal.
MAJ Indicates the major alarms in the network at the local terminal.
MIN Indicates the minor alarms in the network at the local terminal.

Supported CPT 50 Panels on the CPT System

  • The CPT system supports up to 20 CPT 50 panels or 880 GE ports on the CPT 600 shelf.
  • The CPT system supports up to 6 CPT 50 panels or 264 GE ports on the CPT 200 shelf.

The limit on the number of ports is not enforced by CTC.

CPT 50 Panel States

The following states are defined for a CPT 50 panel that is configured in the CPT system:

  • Pre–provisioned—When the 10GE ports on the fabric or the line card are configured as IC ports and when these IC ports are associated with a Fan-Out-Group (FOG).
  • Loading—When the CPT 50 panel has booted up with the IOS image and when the line card version of IOS is being downloaded from the fabric card.
  • Active—When the CPT 50 panel boots up with the line card image and the application initialization is completed.

CPT 50 Panel Connectivity to the Fabric or Line Card

If the CPT 50 shelf loses connectivity to the fabric or line card due to interconnect (IC) link down events, the CPT 50 shelf reloads after the last IC link in the FOG (Fan-Out-Group) fails. This reload occurs after the configured carrier time delay. If there is a connection loss due to remote failures, the CPT 50 shelf reloads after detecting the failure time-out period (5 seconds) for the last link that was active. When the reload is complete, the CPT 50 shelf tries to reestablish the connection to the fabric or line card by performing the discovery operation. If the discovery operation is not successful within 5 minutes, the CPT 50 shelf reloads again. This cycle is repeated thrice with a reduction in the time-out period (30 seconds), until the discovery operation is successful. In the event of successful discovery, the CPT 50 shelf reestablishes the connection to the fabric or line card, else the CPT 50 shelf transits to the idle state and then attempts to connect to the fabric or line card.

Interlink Protection

If one of the links in the FOG is down, the traffic sent on that link is switched and distributed to the remaining active links in the FOG.

Software Restrictions

The following software restrictions apply to the CPT 50 panel:

  • The CPT system supports up to 880 GE ports on the CPT 600 shelf and these ports are distributed among 1 to 20 CPT 50 panels.
  • The CPT system supports up to 264 GE ports on the CPT 200 shelf and these ports are distributed among 1 to 6 CPT 50 panels. The limit on the number of ports is not enforced by CTC.
  • Each CPT 50 panel can be connected to only one fabric or line card at a time.
  • Only one FOG can be created for each CPT 50 panel.

Pre-provisioning

The following can be pre-provisioned through CTC:

  • Fabric card
  • Line card
  • FOG
  • TEN-GE PPMs
  • Port states
  • OTN parameters

The ONE-GE and FE PPMs are not pre-provisioned by default.

Warning

Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Statement 1056


Warning

Class 1 laser product. Statement 1008


Caution

Always use the supplied ESD wristband when working with a CPT 200 and CPT 600 shelf. For detailed instructions on how to wear the ESD wristband, refer to the Electrostatic Discharge and Grounding Guide for Cisco CPT and Cisco ONS Platforms.


Note

If protective clips are installed on the backplane connectors of the cards, remove the clips before installing the cards.


Note

If you install a card incorrectly, the FAIL LED flashes continuously.

Procedure
    Step 1   Navigate to the Cisco Transport Planner shelf layout for the node where you will install the fabric or line card.
    Step 2   Remove the card from its packaging, then remove the protective clips from the backplane connectors.
    Step 3   Open the card ejectors.
    Step 4   Hold the card firmly and align it to the guard rails and slide it inside the slot until the card plugs into the receptacle at the back of the slot designated by the Cisco Transport Planner shelf layout.
    Step 5   Verify that the card is inserted correctly and simultaneously close the ejectors on the card.
    Note    It is possible to close ejectors when the card is not completely plugged into the backplane. Ensure that you cannot insert the card any further.
    Note    If you install the card in the wrong slot, CTC will raise a MEA (EQPT) alarm. To clear this alarm, open the ejectors, slide the card out, then insert it in the correct slot.

    After you install the card, the FAIL, ACT, and SF LEDs will go through a sequence of activities. They will turn on, turn off, and blink at different points. After approximately 2 to 3 minutes, the ACT or ACT/STBY LED turns on. The SF LED might persist until all card ports connect to their far-end counterparts and a signal is present.

    Note    Until a card is provisioned, the card is in the standby condition and the ACT/STBY LED remains amber in color.
    Step 6   If the card does not boot up properly or the LEDs do not progress through the activities described in step 5, check the following:
    • When a physical card type does not match the type of card provisioned for that slot in CTC, the card might not boot and CTC will show a MEA (EQPT) alarm. If the card does not boot, open CTC and ensure that the slot is not provisioned for a different card type before assuming that the card is faulty.
    • If the red FAIL LED does not turn on, check the power.
    • If you insert a card into a slot provisioned for a different card, all LEDs turn off.
    • If the red FAIL LED is on continuously or the LEDs behave erratically, the card is not installed properly.

    If any of these conditions are present, remove the card and repeat steps 3 to 5. If the card does not boot up properly the second time, contact your next level of support.

    Note    Until a card is provisioned, the card is in the standby condition and the ACT/STBY LED remains amber in color.

    Stop. You have completed this procedure.

    Required/As Needed As needed
    Onsite/Remote Onsite or remote
    Security Level Provisioning or higher

    By default, the SFP+ ports on the fabric or line cards are configured as 10GE ports. These ports need to be configured as IC ports and associated to a FOG to connect these ports to the CPT 50 panel. FOG is a logical channel that consists of a bundle of 10GE IC ports.

    The CPT 50 panel can be connected to the fabric card using two IC ports. The CPT 50 panel can be connected to the line card using four IC ports.

    The 4 SFP+ ports that are displayed as 1+ 2+ 3+ 4+ on the faceplate of the CPT 50 panel are displayed as 45, 46, 47, 48 in CTC. This includes the display in Alarms and Performance Monitoring.


    Note
    You can create only one FOG for each CPT 50 panel.
    Procedure
      Step 1   Complete the NTP-J22 Log into CTC procedure at a node where you want to configure the SFP+ ports as IC ports.
      Step 2   From the View menu, choose Go to Home View.
      Step 3   Right-click the fabric or line card and choose Open Packet Transport System View. The Packet Transport System View dialog box appears.
      Step 4   Click the Fan-Out Groups tab.
      Step 5   Click Create. The Create/Edit Fan-Out Group dialog box appears.
      Step 6   From the Fan-Out Group ID drop-down list, choose a FOG ID. FOG ID is the virtual slot ID of the CPT 50 panel and takes values from FOG 36 to FOG 55.
      Step 7   From the Card Slot drop-down list, choose a slot.
      Step 8   From the Available Fan–Out Ports area, choose the required ports that you want to configure as IC ports and move these ports to the Available Fan–Out Group Member Ports area.
      Step 9   Click Apply to create a FOG that consists of the selected ports.
      Note    The CPT 50 panel comes up only when the SFP+ port of the card from where it is connected is not in OOS,DSBLD administrative state.

      Stop. You have completed this procedure.

            ANSI Rack Installation

            The CPT 50 shelf is mounted on a 19-inch (482.6-mm) or 23-inch (584.2-mm) equipment rack. If the shelf is mounted in the front position, then it projects 0.9 inches (22.86 mm) from the front of the rack. If the shelf assembly is mounted in the middle position, then it projects 4.3 inches (109.22 mm) from the front of the rack. The shelf mounts in both Electronic Industries Alliance (EIA) standard and Telcordia-standard racks. The shelf assembly is a total of 17.4 inches (442.4 mm) wide with no mounting ears attached. Ring runs are not provided by Cisco and might hinder side-by-side installation of shelves where space is limited.

            The CPT 50 shelf measures 1.7 inches (43.1 mm) high, 19 or 23 inches (482.6 or 584.2 mm) wide (depending on which way the mounting ears are attached), and 9.1 inches (231.1 mm) deep.

            The following figure shows the dimensions of the CPT 50 shelf in a 19-inch ANSI rack configuration with brackets mounted in the front position.

            Figure 8. CPT 50 Shelf Dimensions for a 19-inch ANSI Rack Configuration

            Mounting Brackets


            Caution
            Use only the fastening hardware provided with the CPT 50 shelf to prevent loosening, deterioration, and electromechanical corrosion of the hardware and joined material.

            Caution
            When mounting the CPT 50 shelf in a frame with a nonconductive coating (such as paint, lacquer, or enamel) either use the thread-forming screws provided with the CPT 50 shelf shipping kit, or remove the coating from the threads to ensure electrical continuity.

            The mounting brackets (19-inch or 23-inch) are used to mount the shelf on a 19-inch (482.6 mm) rack or a 23-inch (584.2 mm) rack.

            Mounting a Single Node

            Mounting the CPT 50 shelf on a rack requires a minimum of 1.75 inches (44.44 mm) of vertical rack space. To ensure the mounting is secure, use two #12-24 mounting screws for each side of the shelf assembly. For an ANSI rack, the brackets can be mounted in the front or middle position.

            ETSI Rack Installation

            The CPT 50 shelf is mounted on a 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) ETSI standard equipment rack. The shelf assembly is a total of 442 mm (17.4 inches) wide with no mounting ears attached. Cisco does not provide ring runs, which might hinder side-by-side installation of shelves where space is limited.

            The CPT 50 shelf measures 43.1 mm (1.7 inches) high, 533.4 mm (21 inches) wide, and 231.1 mm (9.1 inches) deep.

            Figure 1 provides the dimensions of the CPT 50 shelf installed on a 600 x 600-mm (23.6 x 23.6-inch) ETSI standard equipment rack. In this figure, the cable guides are attached to the mounting brackets.


            Caution
            When mounting a shelf in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
            Figure 9. CPT 50 Shelf Dimensions for an ETSI Rack Configuration

            Mounting a Single Node

            The CPT 50 shelf requires 1.75 inches (44.44 mm) minimum of vertical rack space. To ensure the mounting is secure, use two M6 mounting screws for each side of the shelf assembly. In an ETSI rack, the brackets can be mounted only in the front position.

                          • CPT 50 shelf with a DC power module (48 V) for ANSI standard
                          • CPT 50 shelf with a DC power module (48 V) for ETSI standard
                          • CPT 50 shelf with a DC power module (24 V) for ANSI standard

                          Note

                          Do not remove the top cover of the CPT 50 shelf.

                          CPT 50 Shelf with an AC Power Module

                          The AC power module converts the AC input current to DC output current. The AC power module has one AC single phase with 3- pole ( line L, Neutral N, and Protective Earth PE) input connector.

                          CPT 50 Shelf with a DC Power Module

                          The CPT 50 shelf with a DC power module can be powered by redundant DC power lines, however a single power line can power the entire CPT 50 shelf.

                          The CPT 50 shelf with DC power module for ETSI standard has two input battery connectors (two poles)— –48V, RET for power terminals A and B.

                          The CPT 50 shelf with DC power module for ANSI standard has single terminal block with four poles— –48V, RET for power terminals A and B.

                          Fan-Tray Assembly

                          The fan-tray assembly is preinstalled on the right side of the CPT 50 shelf. The fan-tray assembly is removable and holds fans and fan-control circuitry for the CPT 50 shelf. The fan-tray assembly should be accessed only if a fan failure occurs.

                          The fan-tray assembly has the following ports:
                          • EOBC (Ethernet Out-of-Band Channel)—An RJ-45 port that supports high bandwidth external connectivity. If the CPT-50 shelf fails to boot up, the EOBC port also called as the disaster recovery port is used to log in to the CPT-50 shelf for troubleshooting.

                            Note
                            The EOBC port is meant only for TAC (Technical Assistance Center) usage.
                          • PPS (Pulse Per Second)—A mini BNC output port that provides timing signals to an external equipment from the CPT 50 shelf .
                          • 10MH—A mini BNC output port that provides timing signals at a frequency of 10 MHz to an external equipment from the CPT 50 shelf and RET for power terminals A and B.
                          • ToD/PPS (Time of Day/Pulse Per Second)—An RJ-45 serial output port that provides time and day information and timing signals to an external equipment from the CPT 50 shelf.
                          • CONSOLE—A USB port that is used to connect a console terminal. The console terminal can be one of the following:
                            • An ASCII terminal or a PC running terminal emulation software
                            • A modem
                          The following figure shows the ports on the fan-tray assembly:
                          Figure 20. Ports on the Fan-Tray Assembly


                          Note

                          The timing signals are compliant with the IEEE 1588 standard.

                          The console port provides access to the CPT 50 shelf either locally (using a console terminal), or remotely (using a modem). Console connections transmit at slower speeds than modems; therefore, the console connection is suited for use with console terminals.


                          Note

                          An RJ-45 serial port is used for TOD/PPS functionality. The two RJ-45 pins 7 and 8 is used for TOD (Time Of Day) functionality and the other two RJ-45 pins 1 and 2 are used for PPS functionality. Even though an RJ-45 cable is used for TOD/PPS connection, a serial link is established. Two mini coax connectors with RG316 1.0/2.3 M/M cables (50 ohm) are used for PPS (Pulse Per Second) and for 10MHz sinusoidal signal. Cable for TOD/PPS and 10MHz shall be shielded.


                          Note

                          For rules about provisioning timing references, see Telcordia SR-NWT-002224.

                          Fan Speed

                          Fan speed is controlled by the microprocessor present in the CPT 50 shelf. The sensors measure the critical component temperature of the CPT 50 shelf. Fan speed options are low, medium, and high.

                          Fan Failure

                          If one or more fans fail on the fan-tray assembly, replace the entire assembly. You cannot replace individual fans. The red Fan Fail LED on the front of the CPT 50 shelf illuminates when one or more fans fail. The red Fan Fail LED clears after you install a working fan-tray.

                              Power and Ground Description

                              Ground the equipment according to Telcordia standards or local practices. The following sections describe how to power and ground the CPT 50 shelf.

                              Note

                              For detailed instructions on grounding the CPT 50 shelf, refer to the Electrostatic Discharge and Grounding Guide for Cisco CPT and Cisco ONS Platforms.

                              ANSI Power and Ground

                              For AC power feed, use the power cable shipped with the CPT 50 shelf. For an AC power supply, the fuse rating must not exceed 10 A or 15 A, depending on the standards in various countries. The overcurrent and short circuit protection must be in accordance with local and national electrical codes. The voltage rating value for AC power ranges between 100 VAC to 240 VAC depending on the standards in various countries. This product is intended for use on the TN and TT power systems.

                              The CPT 50 shelf for 48 VDC power supply has redundant –48 VDC #14 single-hole lug power terminals. The terminals are labeled RET(A), RET(B), -48V(A), and -48V(B) on the power module. See the figure below:

                              Figure 27. CPT 50 Shelf for 48 VDC Power Supply

                              The CPT 50 shelf for 24 VDC power supply has redundant –24 VDC #14 single-hole lug power terminals. The terminals are labeled RET(A), RET(B), -24V(A), and -24V(B) on the power module.

                              To install redundant DC power feeds, use four power cables and one ground cable. For a single power feed, only two power cables (#14 AWG or larger, copper conductor, 194 degrees Fahrenheit [90 degrees Celsius] minimum) and one ground cable (#8 AWG or larger) are required. Use a conductor with low impedance to ensure circuit overcurrent protection. However, the conductor must have the capability to safely conduct any faulty current that might be imposed.

                              For a 24 VDC power supply, the fuse rating must not exceed 15 A. The voltages –20 VDC and –28.3 VDC are, respectively, the minimum and maximum voltages required to power the chassis. The nominal steady state voltage is -24 VDC.

                              For a 48 VDC power supply, the fuse rating must not exceed 10 A. The voltages –40.5 VDC and –57.6 VDC are, respectively, the minimum and maximum voltages required to power the chassis. Functionality is guaranteed at -40 VDC input voltage, according to GR-1089. The nominal steady state voltage is -48 VDC.

                              We recommend the following wiring conventions, but customer conventions prevail:
                              • Red wire for battery connections (–48 VDC or -24 VDC).
                              • Black wire for battery return connections (RET).
                              • The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE.

                              The ground lug must be a dual-hole type, UL Listed, CSA certified, and rated to accept the #8 AWG cable. Two ground threaded holes with M4 screws are provided on the CPT 50 shelf to accommodate the dual-hole lug. See the figure below:

                              Figure 28. Ground Points on the CPT 50 Shelf

                              ETSI Power and Ground

                              The CPT 50 shelf for ETSI has redundant –48 VDC power connectors (DSUB for DC power module) on the DC power module. To install redundant power feeds, use the two power cables shipped with the CPT 50 shelf and one ground cable. For a DC power supply, the fuse rating must not exceed 10 A. The voltages –40.5 VDC and –57.6 VDC are, respectively, the minimum and maximum voltages required to power the chassis. The nominal steady state voltage is -48 VDC.

                              For AC power feed, use the power cable shipped with the CPT 50 shelf. For an AC power supply, the fuse rating must not exceed 10 A or 15 A, depending on the standards in various countries. The overcurrent and short circuit protection must be in accordance with local and national electrical codes. The voltage rating value for AC power ranges between 100 VAC to 240 VAC depending on the standards in various countries. This product is intended for use on the TN and TT power systems.


                              Caution

                              Use only the power cables shipped with the CPT 50 shelf. The part number of the cables is Cisco PN 72-4974-XX and the PID is CPT-DC-CBL-E=.

                                        Procedure
                                          Step 1   Using a voltmeter, verify the office battery and ground at the following points on the fuse panel:
                                          1. To verify the power, place the black test lead of the voltmeter to the return (RET). Place the red test lead on the BAT-A connection and verify that:
                                            • For a 24 VDC power supply, the voltage is between –20 VDC and –28.3 VDC. Place the red test lead on the BAT-B connection and verify that it is between –20 VDC and –28.3 VDC.
                                              Note   

                                              The voltages –20 VDC and –28.3 VDC are, respectively, the minimum and maximum voltages required to power the CPT 50 shelf that has 24V DC power supply. The nominal steady state voltage is -24 VDC.

                                            • For a 48 VDC power supply, the voltage is between –40.5 VDC and –57.6 VDC. Place the red test lead on the BAT-B connection and verify that it is between –40.5 VDC and –57.6 VDC.
                                              Note   

                                              The voltages –40.5 VDC and –57.6 VDC are, respectively, the minimum and maximum voltages required to power the CPT 50 shelf that has 48V DC power supply. The nominal steady state voltage is -48 VDC.

                                          2. To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red test lead on the BAT-A return ground and verify that no voltage is present, that is, meter reading must be 0 VDC. Place the red test lead on the BAT-B return ground and verify that no voltage is present, that is, meter reading must be 0 VDC.
                                          Step 2   To power up the node, insert the fuse into the fuse position according to site practice. For a 24 VDC power supply, the fuse rating must not exceed 15 A. For a 48V DC power supply, the fuse rating must not exceed 10 A.
                                          Step 3   Using a voltmeter, verify the CPT 50 shelf for –48 VDC or –24 VDC battery and return:
                                          1. To verify the BAT-A of the shelf, place the black lead of the voltmeter to the return. Place the red test lead to the –48V or –24V (BAT-A battery connection) red cable. For a 48 VDC power supply, verify that it reads between –40.5 VDC and –57.6 VDC. For a 24 VDC power supply, verify that the voltage reads between –20 VDC and –28.3 VDC. Then place the red test lead of the voltmeter to the RET1 (BAT-A return ground) black cable and verify that no voltage is present, that is, meter reading must be 0 VDC.
                                            Note   

                                            For a CPT 50 shelf that has 24 VDC power supply, the voltages –20 VDC and –28.3 VDC are, respectively, the minimum and maximum voltages required to power the CPT 50 shelf. The nominal steady state voltage is –24 VDC. To prevent damage to the CPT 50 shelf, the voltage must not exceed -30 VDC.

                                            Note   

                                            For a CPT 50 shelf that has 48 VDC power supply, the voltages –40.5 VDC and –57.6 VDC. are, respectively, the minimum and maximum voltages required to power the CPT 50 shelf. The nominal steady state voltage is –48 VDC.

                                          2. To verify the BAT-B of the shelf, place the black test lead of the voltmeter to the return. Place the red test lead to the –48 V or –24 V (BAT-B battery connection) red cable. For a 48 VDC power supply, verify that it reads between –40.5 VDC and –57.6 VDC. For a 24 VDC power supply, verify that the voltage reads between –20 VDC and –28.3 VDC. Then place the red test lead of the voltmeter to the RET2 (BAT-B return ground) black cable and verify that no voltage is present, that is, meter reading must be 0 VDC.
                                          3. To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red test lead on the BAT-A return ground and verify that no voltage is present, that is, meter reading must be 0 VDC. Place the red test lead on the BAT-B return ground and verify that no voltage is present, that is, meter reading must be 0 VDC.
                                          Step 4   Return to your originating procedure (NTP).

                                                When connecting an optical fiber patch cord between the CPT 50 shelf and the optical card ports in the Cisco ONS 15454 M6 or Cisco ONS 15454 M2, use the electrostatic discharge wristband supplied with the Cisco ONS 15454 M6 or M2.


                                                Note

                                                Always clean all the fiber connectors thoroughly before making the connection with the mating adapter. Very small particles can permanently damage the end of the mating fiber inside the CPT 50 shelf, which makes regular cleaning imperative. For cleaning instructions, see NTP-J60 Clean Fiber Connectors.


                                                Note

                                                The CPT 50 shelf features LC/UPC bulkhead adapters. Always use fiber-optic cables equipped with the corresponding (LC/UPC) connector type. Using any other type of connector results in damage to the connector or adapter, or both.

                                                Procedure
                                                  Step 1   Place the LC/UPC cable connector in front of the corresponding bulkhead adapter on the front panel of the CPT 50 shelf.
                                                  Step 2   Align the keyed ridge of the cable connector with the slot in the receiving adapter.
                                                  Step 3   Gently push the cable connector into the adapter until you hear a click, which indicates that the latching system is engaged.
                                                  Step 4   Route the fiber cables through the cable guide (left and right side). A tie-wrap is tied around the fiber and cables through the cable guide.

                                                  The cables are routed through the cable guide in an ANSI (23-inch) rack configuration, as shown in this figure.

                                                  Figure 39. Cable Management in an ANSI Rack Configuration

                                                  The cables are routed through the cable guide in an ETSI rack configuration, as shown in this figure.

                                                  Note   

                                                  If no cable guide is installed, bind the cables and fibers using the tie-wrap.

                                                              Caution
                                                              In order to ensure system reliability, the CPT 600 or CPT 200 shelf must have all their slots equipped with either cards or fillers.

                                                              Note
                                                              The fabric and line cards are inserted in a CPT 600 or CPT 200 shelf. The line card filler (15454-M-FILLER) must be installed in unused and empty slots to ensure proper air flow and electromagnetic interference (EMI) requirements during the CPT 200 or CPT 600 operation. In the CPT 200 shelf, the line card filler can be installed in Slot 2 and Slot 3. In the CPT 600 shelf, the line card filler can be installed in slots 2, 3, 4, 5, 6, and 7. The line card fillers have no card-level LED indicators. CTC does not detect filler cards. This support may be added in later releases.
