remove both the I/O blades and the accompanying fan blades from
the 9U Library Expansion Module. For details, see Adding,

Before removing a module, you must first remove all 9U Library
Expansion Modules (if any) positioned above it. Disconnect all power
cords, network data cables, and module-to-module cables from the
module you are removing or replacing and all modules located above
it. Then remove the modules.
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.
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.
Note:
If the library is installed in a rack, you need to perform
additional steps to remove modules from and place
modules into the rack. See Installing the Library in a Rack
on page 333 for more information.
