Cisco ASR 9006 Router Fan Tray
The fan tray contains six axial 92-mm (3.62-in) fans. There is a fan control board at the back end of
each tray with a single power/data connector that connects with the backplane.
The fan tray aligns through two guide pins inside the chassis, and is secured by one captive screw.
The controller board floats within the fan tray to allow for alignment tolerances.
A finger guard is adjacent to the front of most of the fans to keep fingers away from spinning fan
blades during removal of the fan tray.
The maximum weight of the fan tray is 39.7 lb (18.0 kg).
