Determining the location

You might need to determine where to install an expansion unit in the rack. Follow this procedure to perform this task either with or without the aid of a rack-mounting template.

1. Plan where you will place the units. Place the larger and heavier units in the lower part of the rack.
2. If necessary, remove the filler panels to allow access to the inside of the rack enclosure where you plan to place the unit.
   
3. If necessary, remove the front and back rack doors.
4. Use one of these procedures to mark the location:
   1. If you have a rack-mounting template, see Marking the location using a rack-mounting template.
   2. If you do not have a rack-mounting template, see Marking the location without a rack-mounting template.
