Rack Mounting an MGX 8230

Mounting Kits

There are two mid-mount brackets in each rack-mounting kit. One mid-mount bracket fits on each side of the MGX 8230 chassis. The mid-mount bracket is 12.25 inches (seven rack units) high and has cutouts along the flange that attaches to the side of the MGX 8230 to allow air flow. The same mid-mount bracket is used for the AC or DC-powered MGX 8230s; thus for an AC-powered MGX 8230, with the optional AC power tray assembly attached underneath the MGX 8230 chassis, the mid-mount bracket does not extend down to AC power tray assembly. There are some shorter screws included in the rack-mount kits for attaching mid-mount brackets; these shorter screws are included specifically for attaching the mid-mount bracket to the side of the MGX 8230 chassis that has the Fan Tray Assembly. Longer screws can interfere with the spinning of the fans in the Fan Tray Assembly. The shorter screws can be used on both mid-mount brackets, however.

Arack-mount kit can be ordered for either 19- or 23-inch racks:

•MGX-8230-MNT19—Mounting kit for 19-inch rack

•MGX-8230-MNT23—Mounting kit for 23-inch rack

These kits include rear and mid-mount brackets as well as the hardware for mounting the brackets to the MGX 8230 chassis. Note that there are extra 10-32 screws included in the 19-inch rack-mounting kit that can be used to secure the MGX 8230 to standard EIA/RETMA rack mounting rails. If the rack being used has metric or other non-standard mounting holes, the customer must supply appropriate mounting screws. Since racks often have metric or non-standard threaded holes, you must supply the screws appropriate for your rack that attach the MGX 8230 to rack mounting rails.

In each 19-inch rack-mounting kit, there are two sets of rear brackets; one set for each side. As shown in Figure 4-2, one bracket fits on the top at the rear of the MGX 8230, and the other fits on the bottom. There is a little bend in the bracket that fits over the top (or bottom) of the MGX 8230 chassis. The other set of brackets fits on the other side of the MGX 8230 chassis.
