4. If there are adjacent modules:
a. From the front of the library, use your fingers or a #2 Phillips screwdriver to loosen the
captive thumbscrews on the replacement module and all modules above it two full turns.
b. From the back of the library, starting with the replacement module and the one below it,
align the modules and lock them together. Repeat for each pair of modules.
i. Use your fingers to loosen the thumbscrew on the alignment mechanism that will
connect the upper module with the lower module.
ii. Lower the alignment mechanism. If you encounter resistance, adjust the upper module
so the pin in the alignment mechanism moves into the hole in the lower module.
When the alignment mechanism is in the locked position, tighten the thumbscrew
with your fingers.
CAUTION: Do not use the alignment mechanism to force the modules into alignment.
The alignment mechanism is designed to hold the modules in position once they are
aligned, but is not intended to adjust the module positions.
