Cooling System Functional Description
Figure 2-69 Cisco ASR 9010 Router Fan Tray
• The fan tray contains 12 axial 120-mm (4.72-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 it is secured by two captive screws.
The controller board floats within the fan tray to allow for alignment tolerances.
• A finger guard is adjacent to the front of most fans to keep fingers away from spinning fan blades
during removal of the fan tray.
• The maximum weight of the fan tray is 13.82 lb (6.29 kg).
Cisco ASR 9006 Router Fan Trays
The Cisco ASR 9006 Router contains two fan trays for redundancy (see Figure 2-70). If a fan tray fails,
it is possible to swap a single fan tray assembly while the system is operational. Fan tray removal does
not require removal of any cables.
Note Both fan trays are required for normal system operation for the Cisco ASR 9010 Router and
Cisco ASR 9006 Router. If both fan trays in the router are pulled out or are not installed, a critical alarm
is raised.
