Mount the adapter block in the bottom 2U of the 3U
volume that the module will occupy, as shown in the
illustration.
3. From the rear of the rack, mount an adapter block at
the same height as each corresponding front adapter
block.
4. From the front of the rack, starting at the rear adapter,
mount the LHS rack shelf for each module into the
adapter blocks on the left side of the rack.
5. From the front of the rack, starting at the rear adapter,
mount the RHS rack shelf for each module into the
adapter blocks on the right side of the rack.
6. Ensure that each rack shelf tab is properly engaged
with the front and rear adapters and will not move in
the front-to-back axis of the rack.
Installing a module in the rack
Procedure
1. From the front of the rack while supporting the bottom
of the module in the areas supported by the rack
shelves, set the back of the expansion module on the
front of the rack shelves. Push the module into the
rack until the front of the module contacts the rack
posts.
2. Verify that this module has been installed directly
above or below its adjacent module and is contained
with the correct 3U volume.
The gap between modules must be less than 4mm.
3. Use a #2 Phillips screwdriver to tighten the captive
fasteners on each side of the expansion module until
they are finger tight. Do not over tighten.
4. Verify that the top cover plate is at the top of the
library and that the bottom cover plate is at the
bottom of the library.
Aligning and connecting modules
Procedure
1. From the front of the library, loosen the screws on
each of the modules two full turns.
2. From the back of the library, starting with the bottom
pair of modules, align each module with the module
below. Repeat for each pair of adjacent modules.
a. Move the alignment lever to the lock position.
If you encounter resistance, adjust the position of
the upper module so the pin in the alignment
mechanism moves into the mating hole in the
lower module.
3. Verify that the lowest module in the library has its
alignment mechanism in the unlocked position.
4. From the front of the library, use a #2 Phillips
screwdriver to tighten the captive fasteners on each
side of all of the modules until the fasteners are finger
tight. Do not over tighten.
5. From the back of the library, connect each adjacent
pair of modules with the expansion interconnect
cables.
