AT&T Lucent Technologies PARTNER Plus Installation And Use Manual page 23

Wall mounting is required.
Mount the backplane on the wall,
leaving at least 6 inches clearance at
the top and sides and 2 feet at the front
and bottom. When using the supplied 7-
foot cords, install within 5 feet of an
electrical outlet not controlled by a
switch and the network interface jacks.
Hold the backplane against the wall...
Using the four screw keyholes in the
backplane as a template, mark screw
locations on the wall. Start four #12
screws, leaving the screw heads
approximately 1/4" away from the wall.
Use screws appropriate for the wall
surface—when loaded with five mod-
ules, the control unit weighs 27.5
pounds. Slip the backplane onto the
screws and tighten them.
A Connect the AC power cord.
B Check all green lights on the front of
the unit. If any lights are out, check to
be sure all circuit breakers are pushed
in (see step 5 on page 2-6), then
remove the power cord and reseat the
module.
A Slide the first 206 module into
the leftmost slot of the backplane. (The
system will not work if a 206 module is
not installed in this slot.) Push slowly
but firmly until the module locks into
place with two snaps, so that it is
attached to the rear of the backplane
and held in place by the locking tab on
the bottom front of the slot. Do not force
the module. If it does not insert easily,
remove the module as shown in step
2B, clear any obstruction, and reinsert.
Insert the next module in the second
slot from the left, aligning the dovetails
between the modules. Insert the
processor module in the center slot and
remaining modules from left to right,
without skipping slots.
LINES
EXTENSIONS
Label the line and extension
jacks as shown above.
B To replace a system module, first
disconnect the AC power cord from the
wall outlet, then slide the control unit
cover off the backplane.
Place one hand on top of the module.
With the other hand, grip the plastic
bracket on the bottom front of the
module,and use one finger to hold
down the locking tab just below the
bracket. Slide the module straight out
being careful not to strain the wires
connected to the module. (If there is not
enough slack in the wires, label and
disconnect them before removing the
module.)
Disconnect the wires from the old
module and plug them into the same
jacks on the new module. (Transfer the
wires one at a time, to make sure that
you know where each wire goes.) Insert
the new module as in step 2A.
WARNING:
There are no customer-
serviceable components
inside the system modules
backplane. Hazardous
voltages within. DO NOT
OPEN THE MODULES!
