Power supplies
The power supply is a hot-swappable Field Replaceable Unit (FRU), allowing n+1 redundant
configurations. The unit is a universal power supply capable of functioning worldwide without
voltage jumpers or switches. The fully enclosed, self-contained unit integrates internal fans to provide
cooling.
The power supply provides three DC outputs (5V standby, 12V, and 48V), providing a total output
power of 320 maximum usable watts. Each power supply plugs directly into the enclosure from the
port side of the unit, mating to internal blind connectors that connect both the DC outputs and the
interface signals to the system backplane. An on/off switch, input filter, and power indicator are
provided in each power supply, as well as a serial EEPROM device that provides identifying
information.
