Chapter 5 Troubleshooting

Troubleshooting the Power Supply

Step 6 If the LED labeled FAN OK fails to light when the switch is connected to a good power source with a known good power cord, there is a malfunction in the fan that cools the power supply. Replace the power supply.

Step 7 If a second power supply is available, install it in the second power supply bay.

Step 8 Check that the LED labeled GOOD is on for the additional power supply. Check that the LED labeled FAIL is off.

Step 9 If the LEDs are not on, repeat the previous procedure to troubleshoot the second power supply.

If you are unable to resolve the problem, or if you determine that either a power supply or backplane connector is faulty, contact Cisco Technical support for instructions.

System Messages and Power Problems

Check for system messages related to the power supply, and refer to the system message guide for your software release. You may need to add a power supply or upgrade to a larger one for your current configuration or verify that the switches are set properly on the power supply. Connect a terminal to the console port, and look for any of the following system messages (there may be others, depending on the software release):

C4K_CHASSIS-2-INLINEPOWEROFF

C4K_IOSMODPORTMAN-4-INLINEPOWERSUPPLYBAD
