11. Power Distribution Board
The power distribution board provides docking connectors for the hot-swappable power supply
modules and distribute power to the main board and SAS backplane. A group of comparators
on the PDB supplies total power consumption information to the system main board. The board
also contains EEPROM FRU information storage. The PDB has no logic on it; it is essentially a
pass-through board.

11.1.1 Remote On/Off (-PS_ON)
The power supply DC outputs will be enabled when this signal is pulled low, below 0.8V. In the
low state, the input will not source more than 1mA of current. The DC outputs will be disabled
when the input is driven higher than 2.4V, or open circuited.
Provisions for de-bouncing will be included in the –PS_ON circuitry to prevent the power supply
from oscillating on/off at startup.
11.1.2 POWER GOOD SIGNAL (POK, or P_GOOD)
A power good signal will be asserted, driven high, by the power supply to indicate that all
outputs are valid. If any of the outputs fails then this output will be driven low.
