3.3.1 ONS 15252 MCU Power and Grounding

Two power supply connectors are located on the backplane of the ONS 15252 MCU. The far-right power connector (as viewed from the rear of the ONS 15252 MCU) is called PS-1 (power supply one), and the far-left power connector is called PS 2 (power supply two), as shown in Figure 3-7. The equivalent PS-1 and PS-2 power supply connector terminals are designated 0V and -48V. Grounding for the ONS 15252 MCU chassis is provided by two lug-type grounding connectors (Figure 3-7).

Note To prevent ground loops, use only one grounding connector.
