hot-swap removal and replacement procedure. Observe all electrical safety procedures while

Air Filter Element Replacement Schedule
The air filter element must be removed and replaced a minimum of every three months when operating in a
computer room with a raised-floor environment. Your environment may require a more frequent change
schedule.
Removing the Air Filter
IMPORTANT When the air filter tray is removed during system operation, the removal event is recorded in
the System Event Log (SEL) of the 14-Slot Shelf as a default reaction. Note that the ShMM
software can be pre-set to react to this event.
