Troubleshooting the Cisco RPS
The key to troubleshooting is to isolate the problem to a specific subsystem. Start by
reading the LEDs on the front panel of the Cisco RPS and any error messages displayed on
the external device console. If you are unable to resolve the problem, refer to the section
"Cisco Connection Online" in the "About This Guide" preface.

Reading the LEDs

The LEDs on the front panel of the Cisco RPS display the current operating condition of
the Cisco RPS:
•
Two AC STATUS LEDs—Left side of the front panel.
•
Four DC STATUS LEDs—Center of the front panel.
•
Two LEDs, FAN and TEMP—Right side of the front panel.
When the Cisco RPS is working properly, all LEDs on its front panel are solid green.
Note Some external devices also include LEDs that show the operating condition of the
Cisco RPS. Refer to the installation guide that accompanied the device for detailed
information about the LEDs.
Figure B-1 shows the LEDs on the front panel of the Cisco RPS, and Table B-1 explains
the meaning of the colors.
