10.1 Power Distribution Board (PDB)
This specification defines the Power Distribution Board (PDB) for using in the Swan Peak
chassis with the Lizard Head Pass motherboard. The PBD supports two 1600W AC or DC
power supplies in a 2+0 non-redundant or 1+1 redundant configuration. The PDB has no
electrical circuit. It only contains connectors and two pull-down resistors.

10.2 Setting the Power Supply Addressing for PMBus and FRU
The PDB has weak pull-
down resistors (10K Ω) on the PSU SMBus addressing pins for A0 and
A1.
10.3 12V Over Current Protection
The PDB has three 12V over current protection circuits. Two are limited to <100A to protect
against catastrophic failures. They rely on the PSUs shutting down in <50msec (supported on
the CRPS family of power supplies). One is a 240VA channel limited to < 20A for protection
against safety energy hazards. Below is a summary of which components are on each 12V rail.
10.3.1 Over Current Protection Circuits
There are three over current protection circuits; two for high power rails and one for 240VA
lower power protection. The PSON# signal will be de-asserted when over current limit is
exceeded.
