Preparing for Installation 2-11

Installing the Rack-Mount Brackets on the Chassis

Bracket placement depends on the type of rack you use to install your access server. This section

describes both a 4-post rack installation and a telco rack installation.

Threaded holes on the chassis sides are strategically located to position and mount bracket hardware.

The dial shelf also has a mounting flange in front for flush-front mounting. If you are mounting the

dial shelf in a 4-post rack, you have the option of using two brackets (one on each side) placed toward

the lower rear of the chassis (see Figure 2-7, position d) to support the chassis in the back. If you are

mounting the dial shelf in a telco rack, you need to offset the dial shelf 5 in. beyond the rack center

post and use six brackets (three on each side) at positions a, b, and c (See Figure 2-7).

Figure 2-7 Dial Shelf Bracket Mounting Hole Positions

If you are installing your access server in a telco rack, proceed to the following section, “Mounting

Forward Brackets for an Offset Telco Rack Installation.”

If you are installing your access server in a 4-post rack, you do not need to install brackets on the

chassis front; use the permanent metal flanges on the chassis front to install the dial shelf in the rack.

(See Figure 2-7.) Proceed to the ““Installing the Dial Shelf in the Rack” section on page 3-6.
