Expansion Module if its chassis is severely damaged.
A library can use up to four 9U Library Expansion Modules to a maximum height of 41U.
There are some configuration settings to take into account when removing and replacing a 9U Library Expansion Module.
• COD licenses remain the same. After the 9U Library Expansion Module is removed, there may be more slots licensed
than are available. Only the available slots appear on the License screen.
• All resources in the removed module(s) are removed. A partition with all resources in the removed module(s) will be
present with no slots or drives. This partition can only be deleted.
Note: The maximum number of 9U Library Expansion Module supported in a library depends on the level of
firmware the library is running. See Updating Library and Tape Drive Firmware for more information.
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.
Removing the 9U Library Expansion Module
1 Before removing a the module, follow the instructions in Preparing to Remove or Replace a Module.
2 Starting with the topmost module of your library, open the I/E station and access doors of each module.
Caution: Before unstacking the modules, the robot assembly must be parked as described in Preparing to
Remove or Replace a Module.
3 Disengage the Y-rails so the modules can be unstacked safely.
