Figure 5-1 Removing or Installing the Fan Tray on the Cisco ASR 9000 Series Router Chassis
To install a fan tray into the chassis:
Step 1 Lift the fan tray (with two hands) and slide it halfway into the module bay.
Step 2 Slowly push the fan tray into the chassis until it mates with the backplane connector at the back of the
module bay.
Caution To prevent damage to the connectors, do not use excessive force when inserting the fan tray into the
chassis.
Step 3 Tighten the captive screw(s) on the fan tray to a torque of 10 +/–1 in-lb to secure it to the chassis.
Step 4 Verify that the (green) OK status indicator on the front of the fan tray goes on. If the OK indicator does
not light, see the “Troubleshooting the Cooling Subsystem” section on page 4-18.
