4.1Installing the Standalone Version in 19-Inch Racks

4.1.1OVERVIEW

The 256-kbps Line Driver standalone version can be installed in 19-inch racks. It is 1U (1.75", 4.4 cm) high and is slightly less than half as wide as the available mounting area.

Two rack-adapter kits are available as special quotes: One kit provides the hardware necessary to install a single unit, and the other provides the hardware necessary to install two units side by side. Sections 4.1.2 and 4.1.3 provide step-by- step instructions for installation of single or dual units.

CAUTION!

Disconnect the units from AC power while performing the following procedures.

4.1.2INSTALLING A SINGLE UNIT IN A 19-INCH RACK

The rack-adapter kit for single-unit installation includes one short bracket and one long bracket. The brackets are fastened with screws to the two side walls of the case, as shown in Figure 4-1.

To prepare the standalone line driver for rack installation, attach the two brackets to the sides of the unit. Do this by inserting screws and flat washers into the two holes at the front of each side of the line driver (nuts are already in place inside the unit).

After attaching the brackets, install the unit in your 19-inch rack by fastening the brackets to the rack’s side rails with four screws (not included in the kit), two on each side.
