CHAPTER

1

Overview of the Cisco RPS

This chapter describes the Cisco 600W RPS, its features, and supported devices. The
Cisco RPS provides power system redundancy to external devices such as routers,
switches, or 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, and redundant-with-reboot configurations.

Table 1-1 lists the supported external devices and power configurations. Figure 1-1 shows
the front panel of the Cisco RPS, and Figure 1-2 shows the rear panel.

Quasi-Redundant Configuration

Quasi-Redundant Configuration

The Cisco RPS provides a quasi-redundant power source for four external devices that use
up to 150W DC each. Youcan use a one-to-one cable (one connector at each cable end) to
connectfourexternaldevices to the four DC output power modules, as shown in Figure 1-3.
The power source is quasi-redundant because there are two AC input power modules for
the Cisco RPS and one DC output powermodule for each external device. The AC input to
the Cisco RPS is fully redundant, but the DC output to the external devices is not.

Fully Redundant Configuration

The Cisco RPS can provide a fully redundant power source for two pieces of equipment.
Youcan useatwo-to-onecable to connect two external devicesto thefourDC output power
modules, as shown in Figure 1-4. 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 two
Cisco RPS DC output power modules 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.

Redundant With Reboot

Redundant With Reboot

By using a second mode of redundant operation called redundant with reboot, you can
connect more hubs and switches to the Cisco RPS and thereby extend its capacity. This
configuration also provides switches and hubs (except the HP 10BaseT Hub-16M) with
additional redundancy.

Redundancy with reboot works for the following devices only: FastHub 100 series,
FastHub 200 series, or FastHub 300 series 100BaseT hubs, Catalyst 1900 series,
Catalyst 2820 series switches, and the Catalyst 2900 series XL switches.

Note Cisco recommends that you use configurations without the AC power plug (that is,

not in redundant-with-reboot mode) connected to the external device, due to the reboot and

downtime—approximately 30 seconds.

The redundant-with-reboot configuration is shown in Figure 1-5, where a straight-through
one-to-onecableconnectsanexternaldevice (the figure shows switches, butthey could also
be hubs) to the Cisco RPS while the device is simultaneously powered by its own internal
power supply (the device AC power plug is connected).

In this configuration, one Cisco RPS can support four devices instead of two. Despite
30 seconds of downtime that occur when using redundancy with reboot, this configuration
provides additional redundancy and extends the capacity of the Cisco RPS.

In this way, the Cisco RPS and external device internal power supply can be connected
simultaneously. A sense circuit in the Cisco RPS reads that the device has its AC power
connected and shuts the Cisco RPS output off. In this way competition between the power
supplies is prevented.

Normally,the external device internal power supply always provides power. If the internal
power system of the external device fails, the device powers down briefly until the
Cisco RPS begins supplying power. When the device comes back up, the Cisco RPS is the
main power source.

Overview of the Cisco RPS 1-7

rps1 Page 8 Monday, September 14, 1998 8:17 AM

Redundant With Reboot

If the Cisco RPS fails or is disconnected, the external device will not power cycle because
its internal power supply has not been disturbed. When both the Cisco RPS and internal
power supply are powered, the LED on the Cisco RPS front panel and the RPS LED on the
external device both blink green.

If you cannot afford the 30-second interruption, unplug the external device AC power cord
and use only the Cisco RPS with the Y-cable. There is no downtime when using the
Cisco RPS with the Y-cable.

Safety Recommendations

Safety Recommendations

Follow these guidelines to guarantee general safety:

• Keep the chassis area clear and dust-free during and after installation.

• Keep tools and chassis components away from walk areas.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf

and roll up your sleeves.

• Wear safety glasses when working under conditions thatmay be hazardous to your eyes.

• Do not perform any action that creates a hazard to people or makes the equipment

unsafe.

Safety Warnings

Safety warnings appear throughout this guide in procedures that, if performed incorrectly,
may harm you. A warning symbol precedes each warning statement. (For information on
safety warnings and translations, see “Installation Guide Conventions” in the “About This
Guide” section.)

Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

• Locate the emergency power-OFF switch in the room in which you are working. Then,

if an electrical accident occurs, you can quickly shut the power OFF.

Warning Read the installation instructions before you connect the system to its power

source.

Warning The device is designed to work with TN power systems.

Warning Before working on equipment that is connected to power lines, remove jewelry

(including rings, necklaces, and watches). Metal objects will heat up when connected to
power and ground and can cause serious burns or weld the metal object to the terminals.

Warning This product relies on the building’s installation for short-circuit (overcurrent)

protection. Make sure that a fuse or circuit breaker is no larger than 120 VAC, 15AU.S.
(240 VAC, 10A international) is used on the phase conductors (all current-carrying
conductors).

Warning This equipment is intended to be grounded. Make sure that the host is connected

to earth ground during normal use.

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded

power extension cables, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

— Use caution; do not become a victim yourself.
— Turn off power to the Cisco RPS.

Safety with Electricity

— If possible, send another person to get medical aid. Otherwise, determine the

condition of the victim and then call for help.

— Determine if the person needs rescue breathing or external cardiac compressions;

then take appropriate action.

Warning Ultimate disposal of this product should be handled according to all national

laws and regulations.

Installing the Cisco RPS

You can set the Cisco RPS chassis on a desktop or install it in a rack.

Warning Only trained and qualified personnel should be allowed to install or replace this

equipment.

Warning Do not work on the system or connect or disconnect cables during periods of

lightning activity.

Warning Before opening the chassis, disconnect the telephone-network cables to avoid

contact with telephone-network voltages.

Warning This equipment is intended to be grounded. Ensure that the host is connected to

earth ground during normal use.

Warning Never defeat the ground conductor or operate the equipment in the absence of a

suitably installed ground conductor. Contact the appropriate electrical inspection authority
or an electrician if you are uncertain that suitable grounding is available.

Warning When installing the unit, the ground connection must always be made first and

disconnected last.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.
