Rackmounted Systems
Use a mounting bracket and secure the Total Access PSU 
to the rack (19” bracket–P/N 1175050L1, 23” bracket–
P/N 1175051L1). Orient the Total Access PSU with the 
cables facing away from the center and secure it with 
four #6 3/8-inch machine screws. A single bracket 
mounts up to 4 Total Access PSUs. Alternately, mount 
the Total Access PSU directly to the rack (or a 
backboard) using two or more of the mounting tabs.

Wallmounted Systems
Position the Total Access PSU (power cords oriented 
downward) and align the outer two holes (on the tabs at 
the corner of the Total Access PSU) with the two 
available machined holes on either side of the Total 
Access OPTI-3. Use two #6 3/8-inch machine screws 
(provided) to secure the Total Access PSU.

Wiring
The Total Access PSU (when ordered for use with these 
systems) is shipped with an adapter cable (ADTRAN
P/N 1200657L10) that has a molded modular connector on 
one end and three ring type terminals on the other (see
Figure 2).

The Total Access PSU powers a single bus (select either A or 
B). Connect the ring-type terminals to the respective termi-
nals on the rear of the chassis using the screws provided. Use 
the following wiring conventions:

Connect the DC wiring harness of the Total Access PSU to 
the adapter using the modular connectors and plug the AC 
plug into the AC power source.
