Fan Tray Servicing
You can remove either of the two fan trays without disruption to service or degradation to system
cooling. It is not advisable to remove more than one from the system at any time.
VMG chassis fans within the chassis fan trays are not individually serviceable: do not attempt to remove
or service a fan within the fan tray. Refer to
Fan Tray Removal
1. Determine which of the Fan Trays has failed by looking at the LED on the Fan Tray faceplate.
If the LED is red, the Fan Tray is not operating properly.
2. Using a 0.250-in slotted screw driver, loosen the lower captive screws on the Fan Tray faceplate.
3. Grasp the Fan Tray handle and slowly guide the fan tray out and away from the chassis.
