From the front of the library, use a #2 Phillips screwdriver and your fingers to loosen the captive
thumbscrews screws two full turns on the module to be removed (circled in Figure 64 on page 127).
Then, slide the module out of the rack.

Moving the library cover plates
Unpack the replacement module and place it on a sturdy work surface. Save the packaging materials to
return the empty module.
The Base Module has removable top and bottom cover plates. The two covers are identical and the
process for removing and installing them is the same for the top and bottom of the module. See
“Preparing top and bottom modules” on page 42 for details. While this procedure refers to moving a cover
from the Base Module, the information is the same for moving a cover from an Expansion Module. The
covers must be removed only if the failed unit does not have the covers (the cover is on another module).
The replacement module is shipped with a bottom cover plate but not a top cover plate. Move the cover
plates as necessary so the replacement module has the cover plates in the same location as the empty
module and the empty module has a bottom cover plate.
