Replacing the Fan Drawer
Eight fans are mounted in the Fan drawer, where the airflow is from right
to left. Should one of these fans fail as indicated by a Fan LED, you are
required to replace the Fan drawer.
1 Unscrew the captive screws on the front panel of the Fan drawer
secured to the Fan chassis.
2 Use the finger grip, pull the Fan drawer out of its slot in the
Backplane.
3 Carefully slide the Fan drawer out through the front panel.
4 Slide in the replacement Fan drawer.
5 Push the Fan drawer firmly into the Backplane, making sure it is
properly seated in its slot.
6 Tighten the captive screws on the front panel of the Fan drawer to the
chassis.
Warning!
The Fan drawer can be replaced when the RMX unit is ON, however a
replacement drawer must be inserted immediately. The temperature increase is
detected by the system, when critical, a system shutdown is initiated.
