Cisco Redundant Power Systems

The Cisco^® Redundant Power System 2300 (RPS 2300) increases availability for converged data, voice, and video networks. The system delivers power supply redundancy and resiliency for a variety of power requirements, including Power over Ethernet (PoE). It helps ensure uninterrupted operation and protection against device power supply failures by providing seamless failover for Cisco switches such as the Cisco Catalyst^® 2960-X, 2960-Plus, 2960-S, 2960, and 3750-E Series Switches and routers such as the Integrated Services Routers.

Flexibility and High Availability

Ease of Use

• The ability to remotely place the RPS or any of the six individual RPS ports in active or standby mode

• Setting priorities for each RPS port

• RPS status reporting, such as the number of power supplies inserted or the availability to back up connected switches

• Switch status reporting, such as a list of the power requirements of each of the attached switches

• Failure and exception history reporting

Product Applications

Figure 2. 10/100 IP Phone and Desktop Computer Connections

• Internal power supply failures in network devices

• Failure of an AC circuit (a circuit breaker tripping, for example)

• Interruption of utility power

Features and Benefits

High Availability/Increased Network Uptime

• Modular power supplies and a fan module offer enhanced availability.

• Less than 60-µs failover capability prevents switch reboot after an internal switch power failure.

• When backed up by a Cisco RPS 2300, a Cisco Catalyst 2960-X, 2960-S, 3750-E, or 3560-E Series Switch is capable of reverting back to its own power supply without rebooting. All other devices may reboot when reverting back to their own power supplies.

• The system supports traditional data-only Ethernet switches as well as PoE switches.

• The system is capable of providing AC source backup when separate circuits are used for the RPS and attached devices.

Ease of Use and Ease of Deployment

• Modular power supplies offer configuration flexibility.

• The system, or individual RPS ports, can be remotely placed in active or standby mode.

• 1-rack-unit form factor provides for efficient wiring closet space utilization

• The system offers configurable RPS port priorities and failover policy.

• Enhanced management capabilities are available through Cisco Catalyst 2960-X, 2960-S, 3750-E, and 3560-E Series Switches. Users can identify and monitor the following activity on the Cisco RPS 2300, using CLI, the CiscoWorks LMS or Cisco Network Assistant network management applications:

– Switch connectivity and power requirements

– Power delivery status for individual RPS ports

– Net power usage

– Backup, failure, and exception history

• The system enables hot insertion of external devices and modular power supplies

• LEDs on front panel and power supplies indicate system and power status.

Cost-Effective Solution

• Innovative power architecture delivers a cost-effective RPS that can connect up to six devices and can actively back-up up to two devices simultaneously, thereby reducing the redundant power cost per device.

• The system supports a wide variety of Cisco Catalyst fixed configuration switches and Cisco Integrated Services Routers.

Connectors and Cabling

• 4.9 ft. (1.5 m) RPS cable

• A 22-pin connector on the RPS end, and two varieties of connectors on the switch end:

– 22-pin connector for Cisco Catalyst 3750-E and 3560-E Series Switches (CAB-RPS2300-E=)

– 14-pin connector for all other Cisco networking devices (CAB-RPS2300=)

• The Cisco RPS 2300 comes with one cable of either variety; others must be ordered separately

• With the C3K-PWR-1150WAC and the C3K-PWR-750WAC power supply, users get a 15A cable, 6 ft. (1.82 m) in length

• Country-specific cables can be ordered as options

Ordering Information

• A typical Cisco RPS 2300 order includes the following:

– Cisco RPS 2300 (PWR-RPS2300)

– 1 RPS cable. Users may order either the CAB-RPS2300-E= compatible with Cisco Catalyst 3750-E and 3560-E Series Switches or the CAB-RPS2300= compatible with all other network devices. Extra cables must be ordered separately or as spares.

– At least 1 power supply, either a C3K-PWR-1150WAC that can back up 48 ports of Class 3 (15.4W) PoE or a C3K-PWR-750WAC that can back up 24 ports of Class 3 15.4W) PoE or 48 ports of Class 2 (7W) PoE. One power cable is included for every power supply ordered. There will be an additional charge for the power supplies, as they are not included in the base price of the RPS 2300.

– 1 fan module (BLWR-RPS2300=)

– 1 power supply bay insert (BLNK-RPS2300=) to block a power supply bay for effective cooling in the Cisco RPS 2300. Note: This insert will only be provided when ordering an RPS 2300 with just one power supply. It will need to be ordered as a spare while ordering an RPS 2300 with two power supplies.

– 1 Cisco RPS 2300 accessory kit (ACC-RPS2300=)

• Orderable spares are listed in Table 9.
