Total Access OPTI-3

Mounting

An additional cable (ADTRAN P/N 1200657L10) is required for connecting the PS/BC to Total Access OPTI-3 systems.

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).

Figure 2. Cable for OPTI-3, MX2810, and NIU3

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:

RED	-48VA or PWR
BLACK	RET
GREEN	Ground Terminal

Table 2. Wiring (OPTI-3, MX2810, NIU3)

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.
