b. Using a screwdriver, remove the screws (C) that attach the shipping bracket (A) to the left and
right flanges of the rack frame. Lift the bracket out and away from the rack frame.
Tip: Save all of the bracket parts that you have removed for any future reinstallation and for
shipping of the 5802 or 5877 expansion unit that might be required.
3.
Go to step 8 on page 15.
4. Unpack the expansion unit as follows:
a. Refer to the kitting list provided with the rack installation kit, and complete a parts inventory.
b. Locate the rack-mounting hardware kit and the system rail assemblies that were included with
your expansion unit.
5. Determine where to install the expansion unit into the rack as follows:
a. Determine where in the rack to place the expansion unit in relation to other system hardware. As
you plan, keep the following steps in mind:
1) Organize larger and heavier units into the lower part of the rack.
2)
Plan to install units into the lower part of the rack first.
3) Record the EIA locations in your plan.
Note: The expansion unit is four Electronic Industries Alliance (EIA) units high. An EIA unit is
44.50 mm (1.75 in.) in height. The rack contains three mounting holes for each EIA unit of height.
This enclosure, therefore, is 177.8 mm (7 in.) high and covers 12 mounting holes in the rack.
b. If necessary, remove the filler panels to allow access to the inside of the rack enclosure where you
plan to place the expansion unit.
