Power Backplane, I C Input Definitions

The power supply backplane has a single I2 C device to detect status and presence
from each power supply. The device is connected through the power control signal
connectors J11 and J10 to the I2 C circuit on the system board and the SCSI hard drive backplane.
The address of the device is 44h.
