THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

•Turn the television or radio antenna until the interference stops.

•Move the equipment to one side or the other of the television or radio.

•Move the equipment farther away from the television or radio.

•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Preface

Audience

This publication is designed for people who have some experience installing networking equipment such as routers, hubs, servers, and switches. We assume the person installing and troubleshooting the RPS 675 is familiar with electronic circuitry and wiring practices and has experience as an electronic or electromechanical technician.

Purpose

This guide documents the hardware features of the Cisco Redundant Power System (RPS) 675. It describes the physical and performance characteristics of the RPS 675, explains how to install the RPS, and provides troubleshooting information.

The RPS 675 provides redundant power for a number of products. Switches in the Catalyst 2950 and Catalyst 3550 families are supported by the Cisco RPS 675 redundant power system (model PWR675-AC-RPS-N1=). The Cisco RPS 675 does not support the Catalyst 3550-24-DC switches.

To determine if your switch can use the RPS 675, refer to your switch documentation or to the online RPS 675 Switch Compatibility Matrix (posted with the RPS 675 documentation on www.cisco.com) for the latest complete list of supported products.

C H A P T E R 1

Product Overview

The Cisco RPS 675 Redundant Power System (RPS), model PWR675-AC-RPS-N1=, provides N+1 redundancy. The RPS 675 provides seamless failover to internal power supply failures for one of up to six switches. The RPS 675 automatically senses when a connected device has experienced an internal power supply failure. It then begins to supply power to the device. The RPS supplies power until the power supply of the failed device is replaced or the device is replaced. You can then return the RPS to active mode so that it is available to supply power to another device.

Note The RPS 675 does not support an automatic switchover to the internal power supply. You must press the Standby/Active button on the RPS so that the switch again uses the internal power supply.

If a connected device fails, the RPS 675 sends status information to the other connected devices and to network management software. This status information alerts administration that these devices are not supported until the failed device or the power supply of the failed device is brought up or replaced. To achieve one-to-one redundancy, you must connect each device to a different RPS 675.

Note The RPS 675 is designed to provide backup for internal power supply failures of connected device power supplies. It is not designed to act as a backup power source that protects against losses of power due to external power outages.

We recommend using an uninterruptable power system (UPS) as protection against power outages.

Chapter 1 Product Overview

Front-Panel Description

•Front-panel LEDs to show status for each output channel, internal power supplies, fans, and temperature

•Quick switchover capability to ensure that the switch does not reboot if the internal switch power supply should fail

•Support for telephone-enabled 24-port devices

•Small form-factor suitable for rack-mounting to provide maximum wiring closet port density

•Two output levels:

––48 VDC with a maximum output of 375 W

–12 VDC with a maximum output of 300 W

The two output levels provide a maximum total output power of 675 W. The –48 VDC mode powers telephone systems in Power over Ethernet (PoE) switches.

•A single 48-inch (1.2-meter) 16-pin-to-14-pin connector cable (CAB-RPS-1614=) to allow connection to an external device. Additional cables can be ordered separately.

Front-Panel Description

The RPS 675 front panel includes the status LEDs for the RPS and a

Standby/Active button.

LEDs

Figure 1-2 shows the Cisco RPS 675 LEDs. The LEDs display the status of the RPS and show whether the RPS is powering a connected device. LEDs can be off, green, or amber. Table 1-1 lists the status LEDs and the meanings of the colors.

Standby/Active Button

The RPS 675 has a front panel Standby/Active button.

Note The RPS is in active mode (Standby/Active LED green) when it powers up. It must be in standby mode every time you connect devices to it.

If you connect a device to the RPS when it is in active mode (Standby/Active LED green), the RPS might unnecessarily begin supplying backup power to the device. This situation might occur if you connect the device before it is powered up, or if the RPS does not immediately sense that the device power supply was supplying power. In this case, the RPS would not be available as a backup power source for other connected devices.

Figure 1-3 shows the Standby/Active button. Press the Standby/Active button to change the RPS 675 from active mode to standby mode when you connect devices. When you change the mode to active, the Standby/Active LED turns green.
