1. From the front of the library, loosen the screws on each of the modules where they are attached to the
rails two full turns.
2. From the back of the library, starting with the bottom pair of modules, align each module with the
module below it. Repeat for each pair of modules. Refer to Figure 44 on page 51.
a. Move the alignment lever of the upper of the pair of modules to the locked or engaged position. If
you encounter resistance, adjust the position of the upper module so the pin in the alignment
mechanism moves into the mating hole in the lower module. If you still encounter resistance, check
to see if the rack rails are installed correctly. Check that the hole for the alignment pin is on the left
rail (looking from the front) toward the back of the rack. See 1 in Figure 42 on page 50.

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 43 on
page 50.
