Installing the Rack Rails and Cage Nuts

You must install two rack rails to support each enclosure. Rack rails have the
following features:
•
Adjustable depth of 60.96 cm to 91.44 cm (24 inches to 36 inches)
IMPORTANT: For proper bus bar installation and clearance, the rack rail depth must be
set from 73.66 cm to 76.20 cm (29 inches to 30 inches).
•
Depth indicator, visible in the middle of the rail
•
"L" and "R" markings to identify left and right rack rails (from the front of the
rack)
WARNING: To reduce the risk of personal injury and damage to the
equipment, always begin by mounting the heaviest item on the bottom of the
rack. Continue to populate the rack from the bottom to the top. Failure to do so
may make the rack unstable.
