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 "Getting Technical Support" section.
This chapter contains the following sections:
The LEDs on the front panel of the Cisco RPS (see Figure 5-1) display the current operating condition of the RPS. Refer to Table 1-2 for the meaning of various LED colors. When the Cisco RPS is working properly, the LEDs are solid green. When there is a problem with any component, the related LED is amber.
Table 5-1 lists symptoms indicating a problem, along with possible causes and suggested corrective actions.
| 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 an 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 an RPS malfunction) even when the RPS is functioning properly. The LEDs display correctly for RPS revision level Z3 or later. The label on the bottom of the 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.
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. | ||||||||||
AC 1 or 2 LED is amber or off. | One of the following has occurred:
| Look at the AC LEDs to determine which AC module is reporting the error.
If the failure persists, one of the AC output modules has failed, and the Cisco RPS needs to be replaced. Contact your Cisco representative or reseller.
| ||||||||||
FAN LED is amber. | One of the fans has failed. The remaining fans switch to full speed to keep the Cisco RPS cool.
| The Cisco RPS continues to operate with a single fan failure. To correct the failure, replace the Cisco RPS. Contact your Cisco representative or reseller.
| ||||||||||
TEMP LED is amber. | The temperature inside the Cisco RPS is too high.
|
If the LED remains amber, replace the Cisco RPS. Contact your Cisco representative or reseller.

Cisco IOS Release 11.2(7)P and later releases support status messages for Cisco 3620/3640 series routers using the Cisco RPS. Cisco IOS Release 11.3(2) and later releases support status messages for Cisco 2600 series routers using the Cisco RPS.
Status messages are not supported for the FastHub 400 series hubs, Cisco 1516M hubs (HP 10BaseT Hub-16M), Catalyst 1900 and Catalyst 2820 series switches, Catalyst 2900 and 3500 series XL switches, Cisco 2500 and 4000 series routers, and the Cisco MC3810 multiservice concentrator.
The show env command (available in Cisco IOS Releases 11.2(7) and later releases) provides an environmental status of the Cisco RPS. An example display follows:
router# show env Power Supply: Redundant Power supply is present. Thermal status is normal. AC status is normal. DC status is normal. Board Temperature: Warning: Board overtemperature condition detected.
 | Caution If the Cisco RPS gets too hot, it shuts down to prevent damage to its components. If thermal shutdown occurs because the cooling system failed or the ambient temperature rose above normal operating limits, a thermal warning displays on the router console, and an SNMP trap is sent before shutdown. |
When a Cisco RPS status failure is detected while connected to Cisco 2600 and 3620/3640 series routers, Cisco IOS software receives an interrupt and displays the error messages on the router console. The following sections describe the console messages and SNMP traps issued following each error condition and after corrective action.
LED status: DC LED 1, 2, 3, or 4 is amber.
Console Error Message:
System detected Redundant Power Supply DC FAIL condition.
*** System Environmental Interrupt ***WARNING: REDUNDANT POWER SUPPLY DC FAIL BIT IS ASSERTED.

The value of ciscoEnvMonSupplyState is a warning.
How to Correct Error:
Check the DC LEDs on the front panel of the Cisco RPS to determine which cable is loose or if the module has failed, and try the corrective actions described in Table 5-1.

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 RPS.
Step 3 Replace the failed external device.
Step 4 If the external device is a hub or switch in redundant-with-reboot mode, connect the external device AC power cord to an AC power outlet to turn on power.
Step 5 Reconnect the new external device to the Cisco RPS power cable.
Step 6 If the external device is a router or concentrator, press the device on/off switch to the on (|) position to power up the device.
The new external device powers up in 10 to 15 seconds.
