Removal and Replacement 3-33
To Prepare the Base Module CRU for Replacement
1. Grasp the base module chassis by the sides and remove it from the shipping
carton.
2. Determine if the CRU is the bottom library module. If it is the bottom module,
install the floor (see "To Install the Floor" on page 3-27).

module and adjust the rails. Never bend the tabs to engage a rail.
4. Push the module into the rack until the front side-tabs approach the front of the
rack rails.
5. Lift the module up slightly, push it into the rack, and set the front tabs down on
the rack rail.
