Chapter 2 Rack Installation en-13
Install the Slide Assemblies Into the
Rack Enclosure
1. Locate and mark the correct positions on the rack’s vertical mounting rails to
install the slide assemblies.
Allow four rack unit spaces (7.0 inches/17.78 cm) or 12 holes per server.
Because the holes on a standard rack enclosure are arranged in sets of 3 holes
spaced 5/8ths, 5/8ths, 4/8ths of an inch apart, determining which holes to use
for attaching a slide assembly depends on exactly where you locate the system.
You can either count the holes so that each slide assembly is installed at the same
height front-to-back and side-to-side in the rack, or use the Rack Buddy included
with your system documentation. Mark the location on the rack enclosure with a felt
tip marker or masking tape.
Install the slide assemblies into the lowest available position. If this is the first
system you are installing into the rack, use holes 3 and 4 or 5. Install additional
servers from the base up.
To use the Rack Buddy, complete these steps:
a. Place the Rack Buddy over the left front vertical rack rail. See the next figure.
b. Move the bottom of the Rack Buddy to the exact location on the rack rail where
the bottom of the system will be located.
c. Adjust the Rack Buddy so that the bottom server screw mounting location is
centered on the space in the Rack Buddy.
