Preparing to Install an Additional 9U Expansion Module
 
Required tools: 
• Phillips #2 screwdriver, for removing and replacing the top cover plate
• T10 TORX screwdriver, for removing and replacing the bottom cover plate
You need to unstack the library to install the new 9U Expansion Module expansion module at the bottom of 
the new library configuration.
1 Upgrade the library firmware to a level that can support the number of modules you are adding. 
2 If you have a partition that spans modules, and you plan to add the new 9U Library Expansion Module 
between those modules, you must delete the partition before adding the new module.
3 Remove all tape cartridges from the library, using the import and export commands of the operator 
panel or Web client.
4 Power off the library.
5 Disconnect all power cords, network data cables, and module-to-module cables from all of the modules.
6 Park the robot assembly in the 5U Library Control Module. Before unstacking the library, the robot 
assembly must be placed in the 5U Library Control Module.
 a. Open the I/E station and access doors of each module.
 b. Using your hands, gently lift the robot assembly into the 5U Library Control Module. The robot 
assembly should glide slowly and with some resistance.
WITHOUT TAPE DRIVES, TAPE CARTRIDGES, OR POWER 
SUPPLIES, A 5U LIBRARY CONTROL MODULE WEIGHS 
APPROXIMATELY 60 LBS (27.2 KG). A 9U EXPANSION MODULE, 
WITHOUT TAPE DRIVES, TAPE CARTRIDGES, OR POWER 
SUPPLIES, EXCEEDS 65 LBS (29.5 KG). 
TO AVOID SERIOUS INJURY, AT LEAST TWO PEOPLE ARE 
REQUIRED TO SAFELY LIFT THE MODULES INTO POSITION. 
If the library contains a partition that spans modules, and you plan to 
install the new 9U Library Expansion Module between those modules, 
you must delete the partition before adding the new module, and re-
create the partition after installing the module. 
Label all cables before you remove them, so you can later reconnect them 
to their proper locations.
Support the robot assembly by holding onto the broad metal X-axis 
base plate. Lifting the robot by the thin metal rod will bend the rod. 
Lifting the robot by the black plastic picker body can damage the 
robot.
