Determining The Location - IBM 7014-T00 Manual

2. Complete a parts inventory. Refer to the kitting list provided with the rack installation kit, and see
"Completing a parts inventory" on page 93.
3. Locate the rack-mounting hardware kit and the system rail assemblies that were included with your
expansion unit.
4. Determine where to locate the expansion unit in the rack. See "Determining the location." This
expansion unit is four Electronic Industries Alliance (EIA) units high. An EIA unit is 1.75 in (44.45
mm) in height. The rack contains three mounting holes for each EIA unit of height.
5. Mark the location. See "Marking the location" on page 61.

Determining the location

You might need to determine where to install an expansion unit in the rack. Use this procedure to
perform this task.
Before installing the expansion unit into a rack, complete the following steps:
1. Read the "Rack safety notices" on page 106.
2. Plan where to place the units. Place the larger and heavier units in the lower part of the rack. These
expansion units are four Electronic Industries Alliance (EIA) units high. The rack contains three
mounting holes for each EIA unit of height. Each of these units, therefore, is 7 in. (177.8 mm) high
and covers 12 mounting holes in the rack.
3. Remove the filler panels to allow access to the inside of the rack enclosure where you plan to place
the unit, see Figure 56 on page 61.
