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 166. 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 167.
6. Slide the Expansion Module back into the rack. See “After the accessor and spooling mechanism
installation” on page 171. 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 166.
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 167.
9. Install the new accessor and spooling mechanism. See “Installing the accessor into the Base
Module” on page 170.
10. Slide the Base Module back into the rack. See “After the accessor and spooling mechanism
installation” on page 171.
Removing or replacing a spooling mechanism
Occasionally, only the robotic spooling cable must be removed and replaced. See “Locating faulty
Components and Resolving Issues” on page 94.
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 172.
2. Refer to “Preparing to remove the accessor and spooling mechanism from the Base Module” on page
166 for the steps in preparing your library.
3. Remove the left magazine to provide clear access to the spooling mechanism.
4. Follow the steps in “Removing the accessor and spooling mechanism from the Base Module” on page
167 to remove the accessor, disconnect the spooling cable, and place it in the park position.
