Installation Procedures; Installing The Control Unit And Modules - AT&T PARTNER II Release 3.1 Installation Manual

Installation Procedures

Before installing the system, be sure you read the safety
instructions on page ii.
WARNING:
There are no customer-serviceable components
inside the system modules or backplane. There are
hazardous voltages within that can cause severe or
fatal personal injury. DO NOT OPEN THE MODULES.

Installing the Control Unit and Modules

Install the control unit's backplane within five feet (1.5
meters) of a properly grounded AC electrical outlet (not
controlled by a switch) and the network interface jacks.
In addition, when you mount the backplane on the wall,
leave at least six inches (15.2 cm) of clearance at the top
and sides, and two feet (0.6 meters) at the front and
bottom to ensure proper ventilation.

Hold the backplane against the wall. (If you are
A)
also installing the expansion carrier, plan to
install it to the right of the primary carrier,
leaving 6" to 24" (15.2 to 61 cm) between the
carriers.)
B) Using the four screw keyholes in the backplane
as a template, mark screw locations on the
wall.
C) Start four #12 screws, leaving the screw heads
approximately 1/4" (.64 cm) away from the
wall.
D) Slip the backplane onto the screws, then tighten
them.
E) If you are mounting the expansion carrier, repeat
this step.

A) Slide the primary processor module into the center
slot of the primary carrier—holding down the
locking tab on the bottom of the slot as you
push in the module will make insertion easier.
B) Push slowly but firmly until the module locks into
place with two snaps, and is attached to the
rear of the backplane and held in place by the
locking tab. Do not force the module. If it
does not insert easily, remove the module,
clear any obstruction, and reinsert it.
If you have an expansion carrier, slide the
C)
expansion processor module into its center
slot until the module locks into place.
