Installing The Chassis In A Rack - Allied Telesis AT-8400 Series Reference Manual

Installing the Chassis in a Rack

The chassis can be installed in a 19-inch rack. It is recommended 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 17. 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.

2. Attach the brackets to the sides of the chassis with four screws (not
provided) on each side.
