Verifying Fan Tray Installation
To verify that the new fan tray is installed correctly and is operating properly, follow these steps:
Before you begin
To check the operation of the fans, you should have powered up the chassis.
Procedure
Step 1
Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure
a) That the fan tray is inserted completely in the chassis
b) That the faceplate is flush with the chassis panel.
c) That the captive installation screws have been tightened sufficiently.
If the fan tray is not installed correctly, the fans may not run at all, or they may run at full speed.
When the fan tray operates at full speed, increased noise levels may be expected.
Important
Step 2
Check if the fan tray LED is lit and is green.
Step 3
If after several attempts the fans do not operate, or if you experience trouble with the installation (for instance,
if the captive installation screws do not align with the chassis holes), contact the Cisco TAC for assistance.
