Changing the Fan Filter
The air inlet fans installed at the bottom of the chassis comes with
a filter to prevent dirt and dust from entering the chassis. You need
to periodically replace the air filter to maintain good chassis air-
flow.
To change the fan filter:
1. Turn off the chassis, then disconnect all cables con-
nected to the chassis, system controller, and peripheral
modules.
2. Lay the chassis upside down in a flat and stable surface.
3. Loosen five screws, lift the fan tray carefully, then lay it
on top of the chassis.
