Chapter 3: Installing the Chassis in an Equipment Rack

86

The procedure in this section explains how to install the chassis in the 
equipment rack. The procedure requires the following items:



#2 Phillips-head screwdriver (not provided)



Six equipment rack screws (not provided)



#2 Phillips-head 10 inch-lbs torque screwdriver (optional — not 
provided)

Do not remove the shipping brace from the front of the AT-SBx3112 
Chassis until after the unit is securely mounted in the rack. The plate 
prevents twisting of the chassis frame and mechanical misalignment 
of the line card slots during shipping and installation.

The chassis may be heavy and awkward to lift. Allied Telesis 
recommends that you get assistance when mounting the chassis in 
an equipment rack.  E30

Allied Telesis recommends having a minimum of three people lift 
and secure the chassis in the equipment rack.

Before installing the chassis in the rack, review the following checklist:



Did you reserve sufficient space in the equipment rack for the 
chassis and install two screws in the rack on which to rest the 
chassis while securing it to the rack? If not, then perform 
“Preparing the Equipment Rack” on page 79.



Did you adjust the brackets so that the front of the chassis is 
positioned correctly for your installation? If not, then perform 
“Adjusting the Equipment Rack Brackets” on page 84.

To install the AT-SBx3112 Chassis in the equipment rack, perform the 
following procedure:

1. While facing the front of the chassis, tilt the top of the chassis toward 

you, as shown in Figure 40 on page 87.
