Cisco Systems Cisco 7000, Cisco 7507 Mounting the Brackets to the Rack Posts

Installation

After you install both brackets in the rack, you must connect the spanner bar on each bracket to the opposite bracket. The spanner bars are required to prevent both ends of the brackets (at the front and rear of the rack) from separating or drifting apart. The cutouts in the brackets are to accommodate the ear brackets that attach to the chassis to the rack. (Refer to Figure 2 on page 4.)

To install the brackets in the rack, you will secure each bracket to a rack post with three

10-32 x 5/8-inch Phillips, pan-head screws. If possible (if the holes line up), use the top-most and bottom most mounting holes in the bracket. Always use the bottom mounting hole on the bracket. If the top mounting hole does not line up with a hole in the rack post, use one of the other two holes near the top of the bracket.

Mounting the Brackets to the Rack Posts

Follow these steps to mount each bracket to a rack post:

Step 1 Measure the space between the inner edges of the left front and right front equipment rack-mounting posts to ensure that it is at least 17.72 inches. The chassis is 17.5 inches wide and must fit between the mounting posts.

Step 2 Measure the distance between the holes in the mounting posts to ensure that it is

18.31inches ( .063 inches). Make several measurements down the length of the posts to ensure they are parallel.

Step 3 Holding the first bracket in the position shown in Figure 10, place the bracket on the inner side of the rack post, with the flanged front edge of the bracket in front of the rack post.
