Removing and Replacing the Fan Tray Assembly
Troubleshooting the Fan Tray Assembly Installation
Use the following procedure to troubleshoot the fan tray assembly if it is not
operating properly after installation.
Caution To prevent overheating, do not operate the system without the fan tray assembly
operational for more than a few minutes.
Step 1 Make sure the router is powered on and that all power cords are connected
properly.
Step 2 Loosen the captive screws and reseat the fan tray assembly.
• Tighten the captive screws to secure the fan tray assembly to the chassis.
Step 3 If after several attempts to reseat the fan tray assembly, replace the existing fan
tray assembly with a spare.
• If the spare fan tray assembly also fails, power off the router and contact a
Cisco service representative for assistance.
