[1.3.260] PMBUS Interface

[1.3.261] Power Supply PMBUS support is a requirement for
the Romley Platform. This requires the connection of the
SMLINK1 interface from the Patsburg SSB (ME) to the Power
Supplies. The ASPEED AST2300 must also interconnect into
this SMBUS radial in order to collect Power Supply FRU infor-
mation and status information.
[1.3.262] NOTE: PMBUS is a protocol that operates on top of
the SMBUS physical interface. The latest PMBUS Specification
Revision 1.2 can be obtained on the PMBus web site
www.pmbus.org or from the responsible engineer.
