Permanently Removing 9U Library Expansion Modules From an
Existing Library
These instructions explain how to permanently remove a 9U Library Expansion Module from the library.
There are some configuration settings to take into account when removing a 9U Library Expansion Module from an existing
library.
• 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.
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
To remove the 9U Library Expansion Module:
1 Before removing a module, follow the instructions in Preparing to Remove or Replace a Module.
2 For each module that you plan to remove, 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.
