Installing, Removing, and Replacing

There are some configuration settings to take into account when adding a 9U Library Expansion Modules to an existing library.
• All COD licenses remain the same. If the current license key does not cover the expanded capacity, you will need a
new license key to use the newly available slots.
• 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 9U Library Expansion Module has been added to the library.
A library can use up to four 9U Library 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 9U expansion
modules. The recommended placement of the control module for 41U library configurations is on top of three 9U expansion
modules and below the top 9U expansion module.
When adding additional 9U expansion modules to an existing library configuration, the recommended placement of the new 9U
expansion module is at the bottom of the existing library configuration (except for the 41U library configurations, where
recommended placement is on top). Installing the new 9U expansion module at the bottom of the existing library configuration
will logically assign slot numbering within the library.

Warning: All libraries taller than 14U must be installed in a rack having a main protective earthing
(grounding) terminal, and power must be supplied via an industrial plug and socket-outlet and/or an
appliance coupler complying with IEC 60309 (or an equivalent national standard) and having a protective
earth (ground) conductor with a cross sectional area of at least 1.5 mm
2
(14 AWG).
To ensure proper airflow and access space, Allow 60 cm (24 inches) in the front and back of the library.
Warning: Without tape drives, tape cartridges, or power supplies, a 5U Library Control Module weighs
approximately 60 lbs (27.2 kg). A 9U Library 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.
