The PSA200 power supply is an International AC input (100-240VAC, 200 Watt) unit provided for the MPP1700. It complies with the compact PCI standard, and is a 3U high 8HP wide. The power supplies can be inserted into slots 18 and 20 of the MPP1700. Operation requires only one power supply. However, when both are installed, these supplies provided redundant load sharing. With both supplies installed, power supplies can be hot swapped without interruption to the system.
