Replacing an External Device

If an external device (hub, switch, router, or concentrator) that is receiving power

from the Cisco RPS fails, you can replace it without powering down the

Cisco RPS or interrupting power to any other external devices. Follow these steps

to replace a failed external device that is connected to the Cisco RPS:

Note Do not power down the Cisco RPS.

Step 1 Power down the external device.

a. If the external device is a router or concentrator, press the on/off switch to the

OFF position.

b. If the external device is a hub or switch configured in redundant-with-reboot

mode, disconnect the AC power cord. (If the hub or switch is in

quasi-redundant mode, Step 2 powers down the switch.)

Step 2 Disconnect the Cisco RPS connector from the external device. Make sure to leave

the AC input power cable connected to the Cisco RPS.

Step 3 Replace the failed external device.
