Corrective Action
The DC status LED numbers correspond
to the DC output connectors on the
Cisco RPS rear panel. Check the LEDs to
determine which connector is affected.
The following steps power down
Note
the external device if it is not
already down.
Disconnect the corresponding output
1.
cable from the external device. The
amber light goes off.
Ensure that the other end of the output
2.
cable is securely connected to the
Cisco RPS and that the connector is
fully seated.
Reconnect the output cable to the
3.
external device.
Ensure that the connector is fully
4.
seated and is attached securely to the
external device.
Wait 15 seconds. The LED is amber
5.
for 15 seconds and then is green.
If the failure persists, the DC output
module has failed, and the Cisco RPS
needs to be replaced. If there is an unused
DC output module, try switching to it as a
temporary solution.
