AT-8400 Chassis Installation Guide

Installing the Chassis in a Rack

The chassis can be installed in a 19-inch rack. Allied Telesyn

recommends that you install the chassis in the rack after installing the

following into the chassis:

❑ AT-8401 management card

❑ AT-8400 line cards

❑ Power supply

Since a fully assembled chassis is heavy, Allied Telesyn recommends two

people lift it into a rack. See the Warning below.

Warning

Safety Hazard- A chassis with one AT-8401management card, five

AT-8411 line cards, and one power supply weighs 12.98 kg (28.85

lbs). Be sure to take the weight into consideration when selecting a

shelf on a rack and lifting the chassis.

For rackmount installation, perform the following procedure:

1. If desired, remove the protective rubber feet from the bottom of the

chassis, if attached, as shown in Figure 6. This is an optional step.

Before removing the feet, carefully place the chassis upside down.

Removing the feet allows you to have more space to install the

Chassis into the rack.
