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.
