7. Equipment Installation
29
28
Warning: Do not install equipment until you have stabilized the enclosure. Install heavier equipment first and
install it towards the bottom of the enclosure. Install equipment starting from the bottom of the enclosure and
proceeding toward the top of the enclosure—never the reverse. If using sliding equipment rails, be careful when
27
extending the rails. Do not extend more than one set of sliding equipment rails at one time. Avoid extending
sliding equipment rails near the top of the enclosure.

Note: The tapped holes in the middle of each rack unit are numbered and also include a small notch to aid identification. A single rack
unit includes the space occupied by the numbered hole and the holes directly above and below.
