Mounting the Chassis on the Wall

This section explains how to mount Cisco 2600 series routers with a chassis height of 1RU on a wall. Mounting a 2-RU chassis to a wall is not recommended, and brackets are not provided for mounting to a wall.

Tip When choosing a wall-mounting location, consider cable limitations and wall structure.

Use 19-inch brackets (shown in Figure 3-2) to wall-mount the chassis. The small brackets provide the most stable installation for the chassis. The rubber feet are required to provide spacing between the wall and the router for ventilation and proper cooling.

Attaching Rubber Feet to the Router

Attach the rubber feet supplied in the accessory kit. See Figure 3-1 for positioning the rubber feet.

Attaching Wall-Mount Brackets to the Router

To install the router on a wall, first attach the brackets on each side of the chassis as shown in Figure 3-16, using plastic washers and slotted hex-head screws. Position the washers so that the narrow shoulder faces the router chassis.

Note The hex-head screws and plastic washers are used only for wall-mounting the router. For rack-mounting, the brackets are attached using Phillips-head screws, without washers.

Figure 3-16 Attaching the Wall-Mount Brackets

Mounting the Router on the Wall

After fastening the brackets to the chassis, mount the chassis on the wall:

•Orient the front and rear of the chassis vertically.

•Position the end nearest the power cable at the top.

•Align the screws (not included) with a wall stud, or use wall anchors.

•Figure 3-17 shows a typical wall-mounted installation.

Figure 3-17 Mounting the Chassis on the Wall

After the router has been installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the "Installing the Chassis Ground Connection" section.

Installing the Chassis Ground Connection

All Cisco 2600 series router chassis require a reliable earth ground connection. You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.

•For NEBS-compliant grounding, use size AWG 6 (13 mm²) wire and the ground lug provided in the accessory kit.

•For NEC-compliant grounding, use size AWG 14 (2 mm²) or larger wire and an appropriate user-supplied ring terminal.

•For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm²) or larger wire and an appropriate user-supplied ring terminal.

To connect the chassis to a reliable earth ground, perform the following steps:

Step 1 Strip one end of the ground wire to the length required for the ground lug or terminal.

•For the NEBS ground lug—approximately 0.75 in. (20 mm)

•For user-provided ring terminal—as required

Step 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.

Step 3 Attach the ground lug or ring terminal to the chassis as shown in Figure 3-18, Figure 3-19, Figure 3-20, or Figure 3-21. For the ground lug, use the two screws with captive locking washers provided. For a ring terminal, use one of the screws provided. Use a number 2 Phillips screwdriver, and tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).

Step 4 Connect the other end of the ground wire to a suitable grounding point at your site.

Connecting to a Console Terminal or Modem

Your router includes asynchronous serial console and auxiliary ports. These ports provide administrative access to your router either locally (with a console terminal) or remotely (with a modem).

Cisco provides the following cables and adapters for connecting your router to a console terminal, PC, or modem:

•One console adapter cable (RJ-45-to-DB-9, blue)

•One modem adapter cable (RJ-45-to-DB-25, black)

This section describes how to connect a console terminal or PC to the console port, and how to connect a modem to the auxiliary port. It contains the following sections:

•Connecting to the Console Port

•Connecting to the Auxiliary Port

•Identifying a Rollover Cable

Note For information on identifying rollover cables, refer to the "Identifying a Rollover Cable" section.

Connecting to the Console Port

To connect a console terminal or a PC running terminal emulation software to the console port on the router, perform the following procedure:

Step 1 Connect the terminal using the blue RJ-45-to-DB-9 adapter cable. (See Figure 3-23.)

For information about console port pinouts, refer to the Cisco Modular Access Router Cable Specifications document available online and on the Documentation CD-ROM.

Note On the Cisco routers, the console port is color-coded blue.

Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 1 stop bit.

Note Because hardware flow control is not possible on the console port, we do not recommend that modems be connected to the console port. Modems should be connected only to the auxiliary port.

Figure 3-23 Connecting to a Console Terminal

Connecting to the Auxiliary Port

To connect a modem to the auxiliary port on the router, perform the following procedure:

Step 1 Connect a modem to the auxiliary port using the black RJ-45-to-DB-25 adapter cable. (See Figure 3-24.)

For information about auxiliary port pinouts, refer to the Cisco Modular Access Router Cable Specifications document available online and on the Documentation CD-ROM.

Note On the Cisco routers, the auxiliary port is color-coded black.

Step 2 Make sure that your modem and the auxiliary port on the router are configured for the same transmission speed (up to 115200 bps is supported) and hardware flow control with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.

Figure 3-24 Connecting a Modem to the Auxiliary Port

Identifying a Rollover Cable

Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify a rollover cable by comparing the two modular ends of the cable. Hold the cables side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure 3-25.) If your cable came from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

Figure 3-25 Identifying a Rollover Cable

Note If the rommon 1> prompt appears, your system has booted in ROM monitor mode. For information on the ROM monitor, see the router rebooting and ROM monitor information in the Cisco IOS Configuration Fundamentals Configuration Guide for your Cisco IOS software release.

Configuring the Router

You can configure your router by using one of the following tools:

•Cisco Router and Security Device Manager. If your router was purchased with a virtual private network (VPN) bundle, Cisco Router and Security Device Manager is installed on the router. See the "Initial Configuration Using SDM" section

•Setup command facility. you can use the setup command facility to prompt you for basic router information. After the configuration file has been created, you can use the CLI or use
Cisco Router and Security Device Manager to perform additional configuration. See the "Initial Configuration Using the Setup Command Facility" section.

•Command-line interface (CLI). If you prefer to use the Cisco IOS CLI, see the "Initial Configuration Using the CLI (Manual Configuration)" section for instructions on how to use the CLI.

Note If you need help with interface and port numbering, see the "Interface Numbering" section on page 1-9.

Initial Configuration Using SDM

If Cisco Router and Security Device Manager has been installed on your router, the following messages appear at the end of the startup sequence:
yourname con0 is now available
Press RETURN to get started.
For configuration procedures using SDM, refer to the quick start guide that shipped with your router.

Initial Configuration Using the Setup Command Facility

This section shows how to use the setup command facility to configure a hostname for the router, set passwords, and configure an interface for communication with the management network. If you see the following messages at the end of the startup sequence, the setup command facility has been invoked automatically:
--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Would you like to enter the initial configuration dialog? [yes/no]:
The setup command facility prompts you for basic information about your router and network, and it creates an initial configuration file.The prompts vary, depending on your router model, the installed interface modules, and the software image. The following example and the user entries (in bold) are shown as examples only.

For a description of the interface numbering, see the "Interface Numbering" section on page 1-9.

Note If you make a mistake while using the setup command facility, you can exit and run the setup command facility again. Press Ctrl-C, and enter setup at the privileged EXEC mode prompt (Router#).

Step 1 To proceed using the setup command facility, enter yes when the power-up messages have ended.
Would you like to enter the initial configuration dialog? [yes/no]: yes
Step 2 When the following messages appear, press Return to enter basic management setup:
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
Would you like to enter basic management setup? [yes/no]: yes
Step 3 Enter a hostname for the router (this example uses 2600):
Configuring global parameters:
Enter hostname [Router]: 2600
Step 4 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration:
The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: xxxxxx
Step 5 Enter an enable password that is different from the enable secret password. This password is not encrypted (less secure) and can be seen when viewing the configuration:
The enable password is used when you do not specify an
enable secret password, with some older software versions, and
some boot images.
Enter enable password: xxxxxx
Step 6 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports other than the console port:
The virtual terminal password is used to protect
access to the router over a network interface.
Enter virtual terminal password: xxxxxx
Step 7 Respond to the following prompts as appropriate for your network:
Configure SNMP Network Management? [yes]:
    Community string [public]:
Step 8 A summary of the available interfaces is displayed:

Note The interface numbering that appears is dependent on the type of Cisco modular router platform and on the installed interface modules and cards.
