The left- and right-hand rack adapter rails have six threaded holes on the front and four
on the back. The multiple holes allow users to install the rack adapter rails in either
whole-unit or half-unit rack mount positions. The six threaded holes are labeled 1
through 6 on the front and 7 through 10 on the back, with stamped numbers.
To install the rack adapter rails in a standard 19-inch (483-mm.) equipment rack, per-
form the following steps:
1. Locate marks on the rack’s left and right front vertical rails. These marks are
1-U spacing marks that appear every 1.75 inches of vertical rack height (see
Figure 2-1).
