Cisco Catalyst 6807-XL User Manual

f) If the IN LED fails to light up after you connect the power supply to a new power source, replace the
power cord, and turn on the switch.
g) If the IN LED then lights up, return the first power cord for replacement.
If this unit has more than one power cord, repeat Step 1 (and all the substeps) for each PSM.
For information about PSM LEDs, see Power Supply Module LEDs, on page 9.
Step 2
If the INPUT OK LED still fails to light up when the switch is connected to a different power source with a
new power cord, the PSM is probably faulty.
If a second PSM is available, install it in the second power supply bay, and contact a Cisco customer service
representative for further instructions.
Step 3
Verify that you have installed the power cord in the correct PEM.
Each PSM and corresponding PEM is numbered.
Step 4
Repeat Step 1, Step 2 , and Step 3 for all the PSMs that you have installed.
If you are unable to resolve the problem, or if you have determined that either a power supply or a backplane
connector is faulty, contact a Cisco customer service representative for instructions.

Troubleshooting the Fan Tray
To isolate a fan tray problem, follow these steps:
Procedure
Step 1
Verify that the FAN LED on the fan tray is green.
If the FAN LED is not green, see Solving Problems at the System Component Level, on page 103 to determine
whether or not the power subsystem is functioning properly.
For information about fan tray LEDs, see Fan Tray LED, on page 8.
Step 2
Check to determine if the FAN LED is red. If the FAN LED is red, the fan tray is not seated in the backplane
or has malfunctioned. Perform the following tasks:
a) To ensure that the fan tray is seated properly, remove the fan tray, and reinstall it. See Removing and
Installing the Fan Tray, on page 54.
b) Restart the system.
c) If the FAN LED is still red, the system detects one or more fan failures. Contact a Cisco customer service
representative for instructions.
