Adding Expansion Modules to an Existing Library

• Partition, I/E station slot, and cleaning slot assignments do not
change; however, unassigned slots may change location.
• Modifying partitions can cause the storage slots to be scattered
throughout the library.
• I/E station slots in the new module(s) are assigned as data storage
slots. You can reconfigure these slots as I/E station slots after the
expansion module has been added to the library.
A library can use up to four expansion modules to a maximum height of
41U.
There are no restrictions on where the control module can be installed in
the library configuration. However, the recommended placement of the
control module for library configurations up to 32U is on top of all
installed expansion modules. The recommended placement of the control
module for 41U library configurations is on top of three expansion
modules and below the top expansion module.
When adding additional expansion modules to an existing library
configuration, the recommended placement of the new expansion
module is at the bottom of the existing library configuration (except for
the 41U, where recommended placement is on top). Installing the new
expansion module at the bottom of the existing library configuration will
logically assign slot numbering within the library.
