Preparation
The system is shipped as an assembled and wired unit
with the exception of connecting the PS/BC to the
backup battery keyed plugs. Installation includes these
main steps:
I. Mounting the cabinet
II. Making wiring connections
Minimum Front Clearance
The Wallmount Cabinet extends 18 inches from the
mounting surface and requires 40 inches front clearance
from the mounting surface to fully open the door, and
28 inches to fully open the main housing.
NOTE
Craft should double check all dimensions in
this practice to actual dimensions on the
cabinet mounting area.
CAUTION
The cabinet with installed equipment weighs
140 pounds and will require two personnel to
safely lift and hang the cabinet.
The Wallmount Cabinet is designed to mount to a
minimum 3/4-inch plywood surface that is securely
fastened to support frames, studs, wall, or an
arrangement of equivalent strength. The Wallmount
Cabinet installs with standard hand tools; special tools
are not required.
The double hinged cabinet is comprised of three main
elements:
• Front door with full-size transparent window.
• Swing open main housing with heavy-duty hinges
and 19-inch equipment rack.
• Wallmount support frame with mounting brackets,
ground bus bar, and cable entry openings.
Mounting Features and Dimensions
The Wallmount Cabinet occupies a nominal area 24
inches wide by 20.25 inches high and requires an
additional 9 inches on the hinge side so the cabinet main
housing can swing fully open, and 6 inches below for
wire access.
Figure 3. Cabinet Mounting Holes
Pilot Hole Location
The Wallmount Cabinet mounts to the wall using eight
1-1/2 by 1/4-inch lag screws with washers. Pilot holes
must be drilled into the mounting surface at the eight lag
screw positions. Locate and mark pilot holes per the
following directions:
Within the designated area for Wallmount Cabinet
mounting, mark a point for the upper left mounting lag
screw.
1. Exactly 16 inches horizontally to the right from
that point mark the spot for the upper right
mounting lag screw. Ensure a level measurement.
2. The Wallmount Cabinet can be mounted and then
the rest of the mounting screw locations can be
drilled from within the cabinet. Refer to I.

I. Mounting the Cabinet
The following procedure describes Wallmount Cabinet
mounting:
1. Assemble required hand tools and mounting
hardware.
2. Check the mounting position to ensure the
Wallmount Cabinet will hang plumb and that
adequate space exists on the hinge side to open the
equipment rack main housing, then drill the two
pilot holes at the marked point locations.
3. Partially insert the outside two top mounting
screws including washers, leaving about a 1/2-inch
gap between the washer and the mounting surface.
4. Ensure the door and main housing are securely
closed then, with two craft personnel, lift and
maneuver the cabinet so as to capture the two
mounting screws on the bracket keyhole notches,
ensure the washers are on the cabinet side of the
notches. Allow the cabinet to slide down so the
screw heads are at the top end of the slots.
5. With the Wallmount Cabinet thus suspended, hold
firm against the mounting surface and firmly
tighten the two lag screws.
6. Drill the holes for the other six lag screws.
7. Insert and tighten the six lag screws
This completes the Wallmount Cabinet mounting
procedure.
II. Making Wiring Connections

Figure 5. Circuit Connections
A cable access plate on the Wallmount Cabinet bottom
panel provides the entry point for office ground, AC
power, network coax/fiber connections, and other
associated wiring.
Ground
WARNING
All grounds must terminate at an approved
ground source. Check metal to metal contact
on all ground connections. Do not combine or
stack connections. Verify ground circuit continuity.
At the inside bottom left of the wallmount support
frame is the cabinet ground bus bar. It has multiple
screw compression terminals for ground connections.
The ground bus is the primary cabinet ground source.
The bus bar is ground connected to the support frame
with a bolt arrangement. All shelf components are
factory connected to the ground bus bar.
Cabinet Office Ground
Connect a customer-supplied, 10 AWG minimum,
office ground wire to one of the unused compression
terminals on the ground bus bar. This is the primary
cabinet to office ground connection.
Power
The two PS/BC units (A and B) mount to the back side
of the battery. Each PS/BC power output originates at
the –54 VDC, 2A OUTPUT connection, and terminates
at a modular plug at the F&A panel. The F&A panel has
a mating connector for each PS/BC output plug. PS/BC
A supplies F&A panel A-side, PS/BC B supplies the Bside. F&A panel circuitry allows the PS/BC units to
power share with one unit picking up the entire load if
the other unit fails.
Power Distribution and Fuses
The F&A panel has 10 individually fused output
terminals on the A-side and an additional 10 on the
redundant B-side. Terminal sets
1A and 1B supply
primary and secondary power input to the OPTI-3. The
associated front panel GMT fuses are 3 amp. The
OPTI-3 power input and return is on power sharing
terminals labeled
RET.
F&A terminal sets
–48V A and RET, and –48V B and
2A and 2B supply primary and
secondary power input to the NIU3. The associated
front panel GMT fuses are 1.5 amp. The NIU3 power
input and return is on power sharing terminals labeled
–48V A and RET, and –48V B and RET.
F&A terminal sets
3A and 3B supply primary and
secondary power input to the MX2800. The associated
front panel GMT fuses are 3 amp. The MX2800 power
input and return is on power sharing terminals labeled
–48V A and RET, and –48V B and RET.
The remaining F&A output terminals are for customer
use.
NOTE
For a fully redundant system each PS/BC must
have an independent AC power source.
1. Connect PS/BC unit A power wire quick
disconnect to F&A panel A-side quick disconnect.
64150WALO3L7-5A Issue 1, June 2004 PRELIMINARY 5

2. Connect PS/BC unit B power wire quick
disconnect to F&A panel B-side quick disconnect.
Refer to System Power Turn-Up below for the
remainder of applying power.
Fiber Optic Jumpers
Fiber optic jumper cables are provided. The 3-meter
cables connect the output of the fiber termination panel
inside the fiber management shelf to the SC style optic
connectors on the OPTI-3 circuit boards.
1. Open the fiber management shelf.
2. Partially insert an OPTI-3 card into the OPTI-3
chassis leaving the board mounted optical
connectors accessible.
3. Carefully route and connect an optic jumper cable
between the fiber termination panel and the
designated OPTI-3 connector. Make use of all
cable protection and management devices.
4. Insert the OPTI-3 card until firmly seated in the
backplane and lock with the lock/eject latch.
5. Repeat the procedure for the remaining OPTI-3
circuit boards.
Network and Field Wiring
The customer is responsible for providing both
network-side and field-side optical fiber and coaxial
cables and making the connections to the appropriate
termination. Refer to the applicable documentation
(Ta bl e 1 on page 2) for information and instructions for
identifying these connections.
Final
All factory installed wiring is dressed and laced during
installation. For those wires that were craft connected,
dress and lace to workmanship standards, take special
care with optical fiber cables. Allow slack for opening
the equipment housing. This completes the wiring
connections.
After all wiring connections are made and verified,
reinstall protective covers and shields that were
removed during the installation process. This step is
necessary to maintain NEBS, UL, FCC, and safety
certification.
3. SYSTEM POWER TURN-UP
System Power Turn-Up assumes that the OPTI-3 and
NIU3 chassis have been outfitted with appropriate
circuit cards, default options factory set, and wiring
connections verified in accordance with the applicable
documentation and this Installation and Maintenance
Practice. If such is not the case complete that task first.
NOTE
Power turn-up should be conducted prior to
connecting network and field data connections.
1. Insert both power supply AC plugs into a 120 VAC
source. The PS/BC LEDs will turn ON green.
The NIU3 status LEDs will turn ON green. The
OPTI-3 LEDs will go through various ON/OFF
sequences. The final OPTI-3 display will show the
STATUS LEDs ON green and the remaining LEDs
ON red or flashing red. Refer to specific unit
documentation for complete LED descriptions.
Test the power share and redundant functioning of
the PS/BCs:
2. Unplug PS/BC unit A AC source. Observe its LED
turning OFF. OPTI-3 and NIU3 LEDs should show
normal, indicating that PS/BC unit B picked up the
load.
3. Reinsert PS/BC unit A AC plug. The PS/BC LED
will turn ON green again indicating normal
operation.
4. Unplug the PS/BC unit B AC source. Observe its
LED turning OFF. OPTI-3 and NIU3 LEDs should
show normal, indicating that PS/BC unit A picked
up the load.
5. Reinsert PS/BC unit B AC plug. Observe its LED
turning ON green indicating normal operation.
For PS/BC LED details, refer to descriptions printed on
the PS/BC chassis, or Job Aid 61175043L3-22.
This completes system power turn-up. If LED indications are normal, operators can proceed with network
and field connections, and management and operation
turn-up functions.
