Removing the Rack Doors
See the procedures for removing doors in the documentation provided
with your rack cabinet.
CAUTION: Because of the size and weight of the rack cabinet doors,
never attempt to remove or install them by yourself.
CAUTION: Store the doors where they will not injure someone if the doors
accidently fall over.
Marking the Rack
For a 2-U system, you must allow 2 U (88 mm, or 3.5 inches) of vertical space
for each system you install in the rack.
Rack cabinets that meet EIA-310 standards have an alternating pattern of
three holes per rack unit with center-to-center hole spacing (beginning at the
top hole of a 1-U space) of 15.9 mm, 15.9 mm, and 12.7 mm (0.625 inch,
0.625 inch, and 0.5 inch) for the front and back vertical rails (see Figure 1-2).
Rack cabinets may have round or square holes.
NOTE: The vertical rails may be marked by horizontal lines and numbers in 1-U
increments. If you want, you can make a note of the number marking on the rack’s
vertical rail. It is not necessary to mark or place tape on the rack.
