3 Remove the LCB from the removed 5U Library Control Module and set it aside.
The LCB stores information about the library's contents and configuration, so you will probably want to
install this LCB in the new 5U Library Control Module. For details about removing the LCB, see
Removing and Replacing the Library Control Blade and LCB Compact Flash Card
4 If the library configuration includes 9U Library Expansion Modules below the 5U Library Control Module,
install them in the library now.
5 Install the new 5U Library Control Module in the library. Lift the 5U Library Control Module, and from the
front of the library, place it in the desired location.
Place the 5U Library Control Module on top of the 9U Library Expansion Module and slide it to the rear
of the unit. A small notch on the bottom of the 5U Library Control Module aligns it with the top of the 9U
Expansion Module.
6 Use the rack ears to fasten the 5U Library Control Module on top of a 9U Expansion Module.
7 If you placed the 5U Library Control Module on top of a 9U Library Expansion Module, secure the two
modules by tightening the two thumbscrews at the base of the front of the module and the two
thumbscrews located at the base of the back of the module. Then lower the module's guide pin (located
at the base of the front of the module) by turning it and pushing it down.
8 Stack all 9U Library Expansion Modules (if any) in their original positions above the 5U Library Control
Module. Use rack ears to fasten the modules to the rack.Then tighten all thumbscrews located at the
base of the front and back of the modules.
