Rack-Mounting the RF Switch with the Cisco uBR7246VXR CMTS

Installing the Brackets on the Cisco uBR 3x10 RF Switch Chassis

This section explains how to install the rack-mount brackets on a Cisco uBR 3x10 RF Switch for flush-rear installations as shown in Figure 3-5 on page 3-10. We recommend that you install the rack-mount brackets so that the MCX connector side of the RF switch (coinciding with the RF cable interfaces on the Cisco uBR7246VXR CMTS) faces the rear of the rack.

Equipment

•Two Brackets (Cisco part number 74-2620-01)

•Four M5 x 8-mm Phillips countersunk screws

•Number 2 Phillips screwdriver

To install the rack-mount brackets on the chassis for a flush-rear configuration, complete the following steps:

Step 1 Locate the threaded holes on the rear sides of the chassis.

Step 2 Align the first rack-mount bracket with the threaded holes in the rear right side of the chassis. See Figure 3-6.

Step 3 Thread the M5 x 8-mm Phillips countersunk screws through the rack-mount bracket and into the side of the chassis. Use a number 2 Phillips screwdriver to tighten the screws.

Step 4 Repeat Step 1 through Step 3 for the other rack-mount bracket.
