Aligning And Connecting Modules - IBM TS4300 User Manual

Figure 42. Library in the rack
Important: Each module must be on its own rails.
5. With a Phillips screwdriver, loosely screw the module to the front of the rack, one screw on each side.
See the circled areas in Figure 42 on page 60.
6. Align the module as needed. Then, tighten the screws on each side of the module. See "Aligning and
connecting modules" on page 60.
7. Repeat steps 2 - 6 to install the rest of the modules into the rack.

Aligning and connecting modules

Aligning the modules ensures that the accessor can move freely between the modules.
About this task
Skip this step if the library does not have Expansion Modules.
Aligning the modules ensures that the accessor can move freely between the modules. The library cannot
operate unless the alignment mechanisms of the upper modules are in the locked position, and the
alignment mechanism of the lowest module is unlocked.
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 45 on page 62.
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
