Determining and marking the location in the rack

You might need to determine where to install the system unit into the rack.

1. Read the Rack safety notices.
2. Determine where to place the system unit in the rack. As you plan for installing the system unit in a rack, consider the following information:
   • Organize larger and heavier units into the lower part of the rack.
   • Plan to install units into the lower part of the rack first.
   • Record the Electronic Industries Alliance (EIA) locations in your plan.
   Note: The server is two EIA units high. An EIA unit is 44.55 mm (1.75 in.) in height. The rack contains three mounting holes for each EIA unit of height. This system unit, therefore, is 89 mm (3.5 in.) high and covers six mounting holes in the rack.
   
3. If necessary, remove the filler panels to allow access to the inside of the rack enclosure where you plan to place the unit, as shown in Figure 1.

4. Determine to place the system in the rack. Record the EIA location.
5. Facing the front of the rack and working from the right side, use tape, a marker, or pencil to mark the lower hole of each EIA unit.
6. Repeat step 5 for the corresponding holes on the left side of the rack.
7. Go to the rear of the rack.
8. On the right side, find the EIA unit that corresponds to the bottom EIA unit marked on the front of the rack.
9. Mark the bottom EIA unit.
10. Mark the corresponding holes on the left side of the rack.
