3.3.2 ONS 15252 Fan Unit Power and Grounding
The fan unit back panel has two power supply connectors. The far-right power connector (as viewed from the rear of the fan unit) is the primary source, and the far-left power connector is the secondary source. These power connectors are designated as 0V and -48V. A pair of grounding pins (M4 screws) is located next to each of the power connectors on the fan-unit back panel.
3.3.3 ONS 15201 SCU Power and Grounding
The ONS 15201 SCU chassis has two power supply connectors. The power supply located on the front of the ONS 15201 SCU chassis is labeled PS-2 (power supply two), and the power supply connector located on the backplane of the ONS 15201 SCU chassis is labeled PS-1 (power supply one)
(Figure 3-6). Lug-type grounding connectors located on the back of the chassis provide grounding. The power supplies convert AC to DC and provide a regulated -48 VDC to the ONS 15201 SCU.
