Installing Fan Trays
Before installing the fan tray, first determine its location. Refer to the figure that applies to your router.
See Removing Fan Trays, page2-18.
Follow these steps to install fan trays in the chassis.
Step1 Lift the fan tray (with two hands) and slide it halfway into the module bay.
Step2 Slowly push the fan tray into the chassis until it mates with the backplane connector at the back of the
chassis bay.
Caution To prevent damage to the connectors, do not use excessive force when inserting the fan tray into the
chassis.
Step3 Tighten the captive screw(s) on the fan tray using the 6-inch long number 2 Phillips screwdriver to a
torque of 10 in-lb to secure it to the chassis.
Step4 Repeat Step 1 through Step 3 for the second fan tray.
Note On the Cisco ASR 9922 Router, the third and fourth fan trays (under the middle cage) are
installed upside down compared to the first and second fan trays (above the middle cage).
