3.1.3 Power Distribution Panel

ONS 15200 site configurations can include a power distribution panel (PDP). The PDP distributes power to the ONS 15200 site and provides power redundancy. It uses input and output fusing to provide system protection.

3.1.4 Fan Unit

All Release 1.0.1 (or later) ONS 15252 MCU site configurations require a fan unit mounted above the ONS 15252 MCU in the equipment rack; Release 1.0 shelves do not use the fan unit. The fan unit contains eight small fans that run simultaneously at constant speed. The fans push air down through the MCU to cool the CLIP modules. The fan unit is powered by its own dual -48 VDC power inlets independently of the MCU. If the fan unit fails, it generates an alarm to indicate multi- or single-fan failure. Located on the front panel of the fan unit are three LEDs to indicate alarm status. Table 3-1lists the LED status and cause of alarm.

			LED	Status	Cause
			Red	Major alarm	Multi-fan failure
			Yellow	Minor alarm	Single-fan failure and/or single
					48 VDC failure
			Green	Normal	Power on
