When installing the cabling to the RSPs, we recommend that you leave a service loop of extra
cabling sufficient to allow for fan tray removal.
Note
Step 3 Secure the fan tray to the chassis using the attached captive installation screws. The recommended maximum
torque is 5.5 in.-lb (.62 N-m).
This completes the procedure for installing or replacing the fan tray in a Cisco ASR 907 Router.
