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 “Preparing to remove the accessor and spooling
mechanism from the Base Module” on page 131.
7. Install the new accessor and spooling mechanism. See “Installing the accessor into the Base Module”
on page 135.
8. Slide the Base Module back into the rack. See “After the accessor and spooling mechanism
installation” on page 136.
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 “Removing or replacing a magazine” on page 142.
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 “Preparing to remove the accessor and spooling mechanism from the Base Module” on
page 131. While minor differences might occur, these instructions for a Base Module also apply to an
Expansion Module.
5. Remove the accessor from the Expansion Module by using Step 1 through Step 7 in “Removing the
accessor and spooling mechanism from the Base Module” on page 132.
6. Slide the Expansion Module back into the rack. See “After the accessor and spooling mechanism
installation” on page 136. While minor differences might occur, these instructions for a Base Module
also apply to an Expansion Module.
7. Extend the Base Module. See “Preparing to remove the accessor and spooling mechanism from the
Base Module” on page 131.
8. Remove the spooling mechanism from the Base Module by using Step 8 through Step 10 in
“Removing the accessor and spooling mechanism from the Base Module” on page 132.
9. Install the new accessor and spooling mechanism. See “Installing the accessor into the Base
Module” on page 135.
10. Slide the Base Module back into the rack. See “After the accessor and spooling mechanism

Removing or replacing a spooling mechanism
Occasionally, only the robotic spooling cable must be removed and replaced. See “Identifying a failed
component” on page 75.
1. Power down the library.
Important: Under normal circumstances, when the library is powered off by using the front Power,
the robot automatically parks and locks into the Base Module behind the Operator Panel. If you are
given a choice during the power down procedure, choose the default park position. To protect the
spooling cable or other sensitive parts, the accessor must be in the Base Module before any
components are removed from the library. If it is not, follow the procedure for returning the accessor
to the base module. See “Returning the accessor to the Base Module” on page 137.
2. Refer to “Preparing to remove the accessor and spooling mechanism from the Base Module” on page
131 for the steps in preparing your library.
