Troubleshooting the Fan Assembly

The 1400 W DC multi-input supply can not be used with other power supply types, but other power supplies in this product line work with the other types during an upgrade. If you mix power supplies in a Catalyst 4500 series chassis, the switch detects the type of power supply in power supply bay 1 (PS1) and ignores the power supply in power supply bay 2 (PS2) while issuing system messages and showing the power supply in bay 2 as in the err-disable state in the output of the show power command. When the power supply in bay 1 is removed, the switch recognizes the power supply in bay 2, and you may then put a new matching power supply in bay 1. Both supplies should now resume normal function.

Troubleshooting the Fan Assembly

Note All fans must be operating or a failure will occur.

Environmental problems may initially appear to be problems with the fan tray. To help isolate a fan assembly problem, follow these steps:

Step 1 Check the status LED on the fan tray.

•If the LED is off and the rest of the system is functioning, the fan tray is not getting power or is not seated correctly on the backplane.

•If the LED is green, the fans are operating normally. There may be conditions impairing fan performance, but they are minimal in impact.

•If the LED is red, one or more fans have failed.

Step 2 Connect a terminal and determine the fan tray status shown by the show environment status CLI command.

Step 3 Look for system messages reporting a temperature problem or problem with the fans. Individual messages may suggest different solutions. Connect a terminal to the console port, and look for any of the following system messages:
