Installing and Removing FRUs
Step 2
Gently slide the fan assembly into the chassis until the fan tray front panel makes contact with the
chassis.
Note
Step 3
Using a screwdriver, tighten the three front panel captive screws by turning them clockwise.
Note
Tighten the fan tray captive screws to 6-8 in-lbs.
Verifying the Fan Assembly Installation
Note
To check the operation of the fans, you need to power up the chassis.
Follow these steps to verify that the new fan assembly was installed correctly:
Step 1
Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that
the fan assembly is inserted completely in the chassis and that the faceplate is flush with the chassis back
panel.
Note
The fan tray has multiple speeds based on the ambient air temperature conditions. The default control
mode setting configures the fans at a maximum speed at startup. After startup, it may take up to 30
seconds for the fans to stabilize to the requested RPM.
Step 2
The fan tray LED should illuminate 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.
