28 System Description 29MAXDATA PLATINUM 90002R Server System
Redundant AC Power Source Operation
The power bay has two AC inlets, labeled AC1 and AC2, located at the rear of the chassis. AC1 is
connected to the inputs of power supply module PS1. AC2 is connected to module PS2 and the
redundant power module PS-Shared, through normally closed transfer switch contacts.
If AC1 input fails or exceeds the specied voltage range, AC2 will transfer power to the two
modules located in the positions labled PS2 and PS-Shared.
If AC2 input fails, the AC transfer switch automatically switches from AC2 to AC1. As result,
AC1 connects to the two power supply modules located in locations PS1 and PS-Shared. After
AC2 recovers, the AC transfer switch resets to its original state. This feature allows the system
to be powered by two separate AC sources. In this conguration, the system continues to
operate without interruption if one of the AC sources fails.
Processor Power Pods
Dedicated power pods supply power to each processor. The input connector of the power pod is
connected to the 12 VDC power on the main board via a short ‘Y’ cable. The output connector of the
power pod mates directly with the edge of the processor package.
