Chassis Installation

You will need a Phillips screwdriver to install the 8820 BAC into a commercial
EIA-standard 19- or 23-inch rack.
For both the 19- and 23-inch wide rack, the chassis can be installed in one of four
depth positions: front flush-mount, 1-inch (2.54 cm) setback, 3-inch (7.62 cm)
setback, or 5-inch (12.7 cm) setback. The chassis is shipped for a 19-inch rack
with a 1-inch setback.
The rack that the chassis will be installed in may or may not have threaded screw
holes. If not, you can use the #12-24 screws and self-retaining nuts provided with
the chassis.

Mounting Brackets Configuration

The chassis is equipped with reversible mounting brackets installed on the chassis
with a 1-inch setback and configured for a 19-inch rack. You may reposition them
for a flush, 3-inch or 5-inch setback, and/or reconfigure them for a 23-inch
NEBS-type rack.

Positioning the Mounting Brackets

The mounting brackets are L-shaped. For 19-inch EIA-type racks, the long leg of
the bracket is secured against the chassis as shown below (left). For 23-inch
NEBS-type racks, the short leg is secured against the chassis as shown below
(right).
