Connecting the Cisco RPS

Connecting the Cisco RPS

This chapter provides instructions on connecting your external device to the Cisco RPS. The chapter is divided into the following major sections:

Power Considerations

Before connecting to external devices, read the power warnings below. We recommend that you disconnect all power before beginning.

Note If you want to connect an additional external device to a Cisco RPS that is already powered up, you can do so without interrupting power to the Cisco RPS or any other connected external devices. Be sure to connect your cable to the Cisco RPS first and then to the external device. However, in a redundant-with-reboot configuration, to ensure proper operation, you must power up the switch or hub before powering up the RPS. Therefore, always connect the switch to AC before you connect it to the RPS. Failure to follow the proper power-up sequence can result in incorrect LED displays.
Warning Attach only the Cisco RPS (model PWR600-AC-RPS) to the RPS receptacle.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Warning Before working on a system that has an On/off switch, turn OFF the power and unplug the power cord.
Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit.

Connecting Hubs

This section provides illustrations and cabling information for connecting the Cisco RPS to the following hubs:

Note The RPS can also be used with the older FastHub 100, 200, and 300 series hubs.

All hubs can use the one-to-one cable configuration for quasi-redundancy. The FastHub 400 series also supports the option of connecting the AC power cord for redundancy with reboot, although this configuration is not recommended. The use of a Y-cable for full redundancy is not supported.

The HP 10BaseT Hub-16M does not support redundancy with reboot and does not support use of the Y-cable for full redundancy.

Follow these steps to connect hubs to the Cisco RPS:

Step 1 Disconnect the AC power cord on the hub.

Step 2 Connect one end of the one-to-one cable to the RPS connector on the hub rear panel. (For connector locations, see Figure 4-1 and Figure 4-2.)

Step 3 Connect the other end of the cable to a Cisco RPS rear-panel connector as shown in Figure 4-3.

Step 4 On the Cisco RPS rear panel, connect an AC power cable to either or both of the power connectors. Use the cable locks on the Cisco RPS to lock the cables in place. (See Figure 4-4.)

Step 5 Connect the other end of the Cisco RPS AC power cable into an AC power outlet.

Step 6 If you are using the redundant-with-reboot configuration (not recommended), power up the switch by connecting the hub AC power cord to an AC power outlet.

Step 7 Power up the Cisco RPS. There is one power switch for each AC input power module. Make sure the power switch is on (|) for each AC power module used.
(See Figure 4-5.)


Figure 4-5: Powering Up the Cisco RPS


The Cisco RPS provides power in 10 to 15 seconds. The Cisco RPS is working properly when all its front-panel LEDs are solid green. If the external device does not power up, refer to "Troubleshooting the Cisco RPS."

Connecting Switches

The Catalyst 1900 series and Catalyst 2820 series switches and the Catalyst 2900 series and Catalyst 3500 series XL switches can use

or

Follow these steps to connect switches to the Cisco RPS:

Step 1 Disconnect the AC power cord on the switch.

Step 2 Connect one end of the one-to-one cable to the RPS connector on the switch rear panel. (For connector locations, see Figure 4-6 through Figure 4-12.)

Step 3 Connect the other end of the one-to-one cable to the Cisco RPS rear-panel connector, as shown in Figure 4-13.

Step 4 On the Cisco RPS rear panel, connect an AC power cable to either or both of the power connectors. Use the cable locks on the Cisco RPS to lock the cables in place. (See Figure 4-14.)

Step 5 Connect the other end of the Cisco RPS AC power cable into an AC power outlet.

Step 6 If you are using the redundant-with-reboot configuration (not recommended), power up the switch by connecting the switch AC power cord into an AC power outlet.

Step 7 Power up the Cisco RPS. There is one power switch for each of the AC input power modules. Make sure the power switch for each connected AC cable is on (|). (See Figure 4-15.)


Figure 4-15: Powering Up the Cisco RPS


The Cisco RPS provides power in 10 to 15 seconds. The Cisco RPS is working properly when all its front panel LEDs are solid green. If the external device does not power up, refer to "Troubleshooting the Cisco RPS."

Note If you are using an 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 RPS is functioning properly. The LEDs display correctly for RPS revision level Z3 or later. The label on the bottom of the RPS shows the revision level.

Connecting Routers and the Cisco MC3810 Concentrator

This section provides illustrations and cabling information for connecting the Cisco RPS to Cisco 2500, 2600, 3620/3640, and 4000 series routers and the Cisco MC3810 multiservice concentrator. All these devices use

or
Note If you did not order your router or concentrator with a Cisco RPS connector installed, you must order a power adapter plate and must install it in place of your existing power supply.
If you need to order a power adapter plate, see Table 3-2, which lists adapter plates and corresponding product order numbers. Contact Cisco Customer Service at 800 553-6387 or 408 526-7209 for ordering information. (See also the "Cisco Connection Online" section in the "About This Guide" preface.)
Device-specific instructions for installing the RPS adapter plate are shipped with the plate and are also available in Cisco Connection Online (CCO) at  http://www.cisco.com.
Note Cisco IOS Software Release 11.2(7)P or later is required when using the Cisco RPS with Cisco 3620 or 3640 series routers.

Follow these steps to connect a router or multiservice concentrator to the Cisco RPS:

Step 1 Power off the router or concentrator by pressing the power switch to the off (O) position.

Step 2 Connect one end of the one-to-one cable or Y-cable to the RPS connector on the rear panel of the router or concentrator, as shown in Figure 4-16 through Figure 4-21.
