Replacing the rack doors

NOTE: Two procedures are provided for task 3. One procedure is for the RapidRails kit,

and one procedure is for the VersaRails kit.

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 two doors where they will not injure someone if the doors accidently fall over.

Marking the Rack

For a 1-U system, 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 back vertical rails

(see Figure 1-3). 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.
