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.

Overview
The Cisco 600W Redundant Power System (RPS) provides power system
redundancy to external devices such as routers, switches, and hubs. The system
includes two fully redundant AC input power modules and four DC output power
modules for connection to external devices. The Cisco RPS supports
quasi-redundant, fully redundant, or redundant-with-reboot configurations,
depending upon the external device.
This chapter provides an overview of the Cisco RPS features, including the
supported external devices and power configurations, in the following sections:
• Features, page 1-1
Features
OL-3654-01
• Supported Devices and Configurations, page 1-2
• Front and Rear Panel Descriptions, page 1-8
• Safety Recommendations, page 1-11
The following features are standard:
• Two AC input power cords
• Two fully redundant AC input power modules
• Four 150W DC output power modules
• Rack-mountable chassis (19-inch rack-mount brackets included)
• Redundant cooling fans
Cisco Redundant Power System Hardware Installation Guide
1-1
Supported Devices and Configurations
• LEDs for AC, DC, fans, and temperature status
• Simple Network Management Protocol (SNMP) support of error messages
for Cisco 2600 series and Cisco 3620/3640 series routers. (There is no SNMP
support for error messages in the Cisco 1516M hub, FastHub 400 series hub,
Catalyst 1900 series switches, Catalyst 2820 series switches, Catalyst 2900
and Catalyst 3500 series XL switches, Cisco 2500 and 4000 series routers,
and the Cisco MC3810 multiservice concentrator.)
The Cisco RPS ships in either of the following configurations:
• With cables (Cisco RPS number PWR600-AC-RPS-CAB)—Includes four
one-to-one (22-pin to 18-pin) cables for connecting to hubs and switches or
for quasi-redundant support for Cisco 2600 series routers; Cisco 3620, Cisco
3640, and Cisco 3725 routers; and Cisco 4000 series routers.
• Without cables (Cisco RPS number PWR600-AC-RPS-NCAB)—Cables
must be ordered separately:
Chapter 1 Overview
–
One-to-one (22-pin to 18-pin) cables for connecting to hubs and switches
or for quasi-redundant support for Cisco 2600 series routers; Cisco 3620,
Cisco 3640, and Cisco 3725 routers; and Cisco 4000 series routers
–
One-to-one (22-pin to 8-pin) cables for quasi-redundant support for
Cisco 2500 series routers and access servers and Cisco MC3810
multiservice concentrators
–
Two-to-one Y cables (22-pin to 18-pin or 22-pin to 8-pin) for fully
redundant support only for routers or concentrators
Note Refer to Table 3-1 on page 3-5 for cable descriptions and order numbers.

1. The Cisco RPS has a demonstrated mean time between failures (MTBF) of greater than 500,000 hours in this mode.
2. The redundant-with-reboot configuration is not recommended because of the reboot and downtime; if you use this
configuration, always power up the switch before you power up the Cisco RPS to ensure correct operation.
3. The Cisco RPS can also be used with the older FastHub 100, 200, and 300 series hubs.
4. If you are using a Cisco RPS with a revision level lower than Z3 with a Catalyst 3508G or a Catalyst 3548 XL switch, the
switch RPS LED and the RPS DC LED might display amber (normally indicating RPS malfunction) even when the Cisco RPS
is functioning properly. The LEDs display correctly for Cisco RPS revision level Z3 or later revision. The label on the bottom
of the Cisco RPS shows the revision level.
5. For simplicity, Cisco 2500 series access servers, such as the Cisco 2509 or the Cisco 2511, are referred to as Cisco 2500 series
routers throughout this guide.
Note You might need to order a power adapter plate for your router or concentrator to
make it compatible with the Cisco RPS. Table 3-1 on page 3-6 lists adapter plates
and order numbers.

Supported Devices and Configurations
Quasi-Redundant Configuration
The Cisco RPS provides a quasi-redundant power source for four external devices
that use up to 150W DC each. This configuration is allowed for all supported
devices. You can use a one-to-one cable (one connector at each cable end) to
connect four external devices to the four DC output power modules, as shown in
Figure 1-1. The power source is quasi-redundant because there are two AC input
power modules for the Cisco RPS and one DC output power module for each
external device. The AC input to the Cisco RPS is fully redundant, but the DC
output to the external devices is not.
Note This is the only recommended configuration for Cisco switches and hubs.

Chapter 1 Overview
Fully Redundant Configuration
The Cisco RPS can provide a fully redundant power source for two of the
supported routers or concentrators. You can use a two-to-one cable (ordered
separately) to connect two external devices to the four DC output power modules,
as shown in Figure 1-2. The two-to-one cable is a Y-shaped cable with two
connectors at one end and one connector at the other end.
In this configuration, the connectors at one end of the Y-shaped cable connect to
two Cisco RPS DC output power modules; the single connector on the other end
of the cable connects to one external device. The power source is fully redundant,
because there are two AC input modules and two DC output power modules
connected to each external device. If any power module fails, there is a full
backup.
Supported Devices and Configurations
Note This configuration is not supported for switches and hubs.
