Removing the Module from a rack
Obtain assistance to lift and stabilize the module during removal and replacement.
v If you are removing a module that has a module immediately above or below it,
1. From the front of the library, use a #2 Phillips screwdriver to loosen the screws two full turns on
the module and its adjacent modules.
2. From the back of the library, unlock the alignment mechanisms that connect the module with the
adjacent modules.
Note: If a blue alignment lever lock is attached to the rear of the module, slide it to the left, then
move the alignment lever. The lever lock has an internal spring, so hold it while the alignment
lever is moved, and it automatically springs back into place after the lever is moved. See Figure 44
on page 47.
