7.5 Rack-Mounted Libraries
Rack-mounted RLS libraries must be extended from their racks for replacing any in-
ternal FRUs. Only front- or rear-mounted FRUs can be replaced without first extend-
ing the RLS out from the rack. Assemblies that can be replaced without extending the
RLS or opening its Top Cover include: Power Supply Module(s), Interface Personality
Module (IPM), Tape Drives and the Air Filter.
DANGER
Extending a rack-mounted RLS causes a dramatic shift in the center-of-gravity of the
rack system. If the system is not securely fastened to the floor or other permanent struc-
ture, it can very possibly tip over when the RLS is extended causing great bodily harm
and damaging all the equipment.
Tips for safely extending and RLS include locking any casters on moveable racks and
having a second person help extend the RLS. While you are pulling the RLS out from the
rack and if you feel the rack tipping stop immediately! Push the RLS back into the rack
and call for assistance.
