NOTE
The maximum power consumption of the general OptiX OSN 3500 subrack is 720 W. Therefore, it is recommended
that you select fuses that support a maximum current of 20 A for the power supply facility.
The maximum power consumption of the enhanced OptiX OSN 3500 subrack is 1100 W. Therefore, it is
recommended that you select fuses that support a maximum current of 32 A for the power supply facility.
The power cables for the subrack are connected to the DC power distribution box before delivery. When installing
the power cables, you only need to connect the power cable connectors to the PIU board in the subrack.
When grounding the subrack, connect the ground bolt on the subrack to the ground point on the column inside the
cabinet. The subrack then is connected to the external ground bar through the PGND cable on the top of the
cabinet.
