Marking the rack
Prerequisites
The rack must be installed. If installing the server in a cabinet, then the doors must be removed.
You must allow 1 U (44 mm, or 1.75 in.) of vertical space for each server 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 in., 0.625 in., and 0.5 in.) for the front and back vertical rails.
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
Caution:
If you are installing more than one server, install the mounting rails so that the first server is
installed in the lowest available position in the rack. If you are installing a UPS in the same
rack as the server(s), install the UPS in the lowest available position in the rack and the
servers above it.
1. Place a mark (or tape) on the rack's front vertical rails where you want to locate the
bottom of the server.
