10 Rack Installation Guide

To mark the rack, perform the following steps:

Place a mark on the rack’s front vertical rails where you want to locate the bottom of the system you are

installing in the rack cabinet.

The bottom of each 1-U space is at the middle of the narrowest metal area between holes (marked with

a horizontal line on some rack cabinets—see Figure 1-3).

Place a mark approximately 8.75 inches above the original mark you made (or count up 15 holes in a

rack that meets EIA-310 standards) and mark the rack’s front vertical rails with a felt-tipped pen or

masking tape (if you counted holes, place a mark just above the top hole). This mark or piece of tape

indicates where the system’s upper edge will be located on the vertical rails (see Figure 1-3).
