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

You must allow 1 U (44 mm, or 1.75 inches) of vertical space for installing the KMM tray.
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 1-2. Rack cabinets may have round or square holes.
NOTE: The vertical rails are sometimes engraved with 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, skip ahead to the procedure "Installing the RapidRails Slide
Assemblies."
NOTE: Installing the 1-U KMM tray in the top U space of the Dell PowerEdge 2410
rack is not recommended.
To mark the rack, perform the following steps:
Use a felt-tipped marker or masking tape to mark the rack's front vertical rails where
1
you want to locate the bottom of the 1-U KMM tray.
The bottom of each 1-U space is at the middle of the narrowest metal area between
the holes (marked with a horizontal line on some rack cabinets). See Figure 1-2.
