Symptom Description of Error Corrective Action

DC LED 1, 2, 3, or 4 is

amber.

Note The DC LED is

always amber

for 10 to 15

seconds after

the DC output

module has

been connected

and the

external device

has been

powered on.

The cable connected to an

internal DC output module is

loose, or the internal DC output

module has failed.

Note If you are using a

Cisco 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 of the

connector to the switch

might display amber

(normally indicating a

Cisco RPS

malfunction) even when

the Cisco RPS is

functioning properly.

The LEDs display

correctly for Cisco RPS

revision level Z3 or

later. The label on the

bottom of the

Cisco RPS shows the

revision level.

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.

Note The following steps power down

the external device if it is not

already down.

1. Disconnect the corresponding output

cable from the external device. The

amber light goes off.

2. Ensure that the other end of the output

cable is securely connected to the

Cisco RPS and that the connector is

fully seated.

3. Reconnect the output cable to the

external device.

4. Ensure that the connector is fully

seated and is attached securely to the

external device.

5. Wait 15 seconds. The LED is amber

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.
