4. Lock the accessor. Standing at the front of the module, move the blue lever to the left, then away from
you, then to the right.
5. Reinstall the bezels that were previously removed.
6. Remove the accessor and spooling mechanism. See āPreparing to remove the accessor and spooling
mechanism from the Base Moduleā on page 120.

on page 124.
8. Slide the Base Module back into the rack. See āAfter the accessor and spooling mechanism

If the accessor is stopped in an Expansion Module that is not near the Base
Module or it cannot move vertically.
1. Remove the left magazine of the Base Module. See āRemoving or replacing a magazineā on page
133. The library must already be powered off. Therefore, you must unlock the magazine by using the
manual release.
2. Disconnect the power supply cables from all of the modules.
3. Using plastic-handled scissors, reach through the left magazine opening of the Base Module and
carefully cut the spooling cable.
4. Extend the expansion module that contains the accessor while carefully guiding the free spooling
cable. See āPreparing to remove the accessor and spooling mechanism from the Base Moduleā on
page 120. While minor differences might occur, these instructions for a Base Module also apply to an
Expansion Module.
