This chapter provides instructions on connecting your external device to the Cisco RPS. The chapter is divided into the following major sections:
•
Power Considerations
• Connecting Hubs
• Connecting Switches
• Connecting Routers and the Cisco MC3810 Concentrator
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 Cisco RPS. Therefore, always connect the switch to AC power before you connect it to the Cisco RPS. Failure to follow the proper power-up sequence can result in incorrect LED displays.
Note A catalyst switch might reload when changing from RPS power to internal power. This can occur on any catalyst switch, except the 3560-E or 3750-E switch, connected to one of the following: Redundant, Power Supplies, PWR 300-AC-RPS-NI, PWR-600-AC-RPS-NI, and RPS2300. To prevent unscheduled downtime, the switch should be powered off during a maintenance window.
Warning Attach only the Cisco RPS (model PWR600-AC-RPS) to the RPS receptacle. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
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. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
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. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Connecting Hubs
This section provides illustrations and cabling information for connecting the Cisco RPS to the following hubs:
•Cisco 1516M hub (HP 10BASE-T Hub-16M) ( Figure 4-1)
•FastHub 400 series hubs ( Figure 4-2)
Note The Cisco 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 10BASE-T Hub-16M does not support redundancy with reboot and does not support use of the Y-cable for full redundancy.
To connect hubs to the Cisco RPS, perform these steps:
Step 1 Disconnect the AC power cord on the hub.
Step 2 Connect one end of the one-to-one cable to the Cisco 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.)
Figure 4-4 Connecting the AC Power Cables to the Cisco RPS
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.
Note If you use the redundant-with-reboot configuration, always power up the hub before you power up the Cisco RPS.
Step 7 Power up the Cisco RPS. There is one power switch for each AC input power module. Make sure that the power switch is in the ON (|) position 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:
•One-to-one cable for quasi-redundancy
or
•One-to-one cable with the switch AC power cable connected for redundancy with reboot (not recommended)
To connect switches to the Cisco RPS, perform these steps:
Step 1 Disconnect the AC power cord on the switch.
Step 2 Connect one end of the one-to-one cable to the Cisco RPS connector on the switch rear panel. (For connector locations, see Figure 4-6 through Figure 4-12.)
