Removing the Rack Doors

See the procedures for removing doors in the documentation provided with your rack
cabinet.

Marking the Rack

You must allow 1 U (44 mm, or 1.75 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 rear vertical rails (see Figure 1-3). Rack cabinets may have round or square holes.

NOTE: Two procedures are provided for task 3, installing the slide assemblies in the
rack. One procedure is for the RapidRails kit, and one procedure is for the VersaRails
kit.
CAUTION: Because of the size and weight of the rack cabinet doors, never
attempt to remove or install them by yourself.
CAUTION: Store the two doors where they will not injure someone if the doors
accidently fall over.
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. If you choose this
method, go to the procedure "Installing the RapidRails Slide Assemblies."
