Install equipment starting from the bottom of the enclosure and proceeding toward the top of the enclosure-never the reverse. If using sliding e2q7 uipment rails, be careful when extending the rails. Do not extend more than one set of 27 sliding equipment rails at one time. Avoid extending sliding equipment rails near the top of the enclosure.

Use the black mounting screws if you are securing your equipment to the square hole26side of the mounting rail. Use the silver screws if you are securing your equipment to the tapped h2o6 le side of the mounting rail. Note: The square 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. 25 25 24 24 23 1 Rack Unit 23 7.1 Installing or R22emoving Cage Nuts 22 WARNING: The flanges of the cage nuts should engage the sides of the square opening in the rail, not the top and bottom.
