Intel® Server Chassis H2000 Family TPS Power Sub-System below the Vfault threshold. Asserting the CR_BUS signal causes all power supplies in Cold Standby state to power ON. Enabling power supplies to maintain best efficiency is achieved by looking at the Load Share bus voltage and comparing it to a programmed voltage level through a PMBus command. Whenever there is no active power supply on the Cold Redundancy bus driving a HIGH level on the bus all power supplies are ON no matter their defined Cold Redundant roll (active or Cold Standby). This guarantees that incorrect programming of the Cold Redundancy states of the power supply will never cause the power subsystem to shut down or become over loaded. The default state of the power subsystem is all power supplies ON. There needs to be at least one power supply in Cold Redundant Active state or Standard Redundant state to allow the Cold Standby state power supplies to go into Cold Standby state. 3.4.1 1200W CRPS Cold Redundancy If the output power is less than 480W (40%). the Cold redundant function will be enable. Thus you will see one PSU working normal. The second PSU will be CR mode. The Power Supply LED is green blinking. Table 25. 1200W CRPS Cold Redundancy Threshold.

Signals that can be defined as low true use the following convention: Signal# = low true. 3.5.1 PSON# Input Signal The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +12V power rail. When this signal is not pulled low by the system, or left open, the outputs (except the +12VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. Refer to below table for the timing diagram. Revision 1.0 23 Intel order number: G59059-001

below the Vfault threshold. Asserting the CR_BUS signal causes all power supplies in Cold
Standby state to power ON.
Enabling power supplies to maintain best efficiency is achieved by looking at the Load Share
bus voltage and comparing it to a programmed voltage level through a PMBus command.
Whenever there is no active power supply on the Cold Redundancy bus driving a HIGH level on
the bus all power supplies are ON no matter their defined Cold Redundant roll (active or Cold
Standby). This guarantees that incorrect programming of the Cold Redundancy states of the
power supply will never cause the power subsystem to shut down or become over loaded. The
default state of the power subsystem is all power supplies ON. There needs to be at least one
power supply in Cold Redundant Active state or Standard Redundant state to allow the Cold
Standby state power supplies to go into Cold Standby state.

1200W CRPS Cold Redundancy
If the output power is less than 480W (40%). the Cold redundant function will be enable. Thus
you will see one PSU working normal. The second PSU will be CR mode. The Power Supply
LED is green blinking.

Control And Indicator Functions
The following sections define the input and output signals from the power supply.
Signals that can be defined as low true use the following convention:

PSON# Input Signal
The PSON

signal is required to remotely turn on/off the power supply. PSON
#
is an active low

open, the outputs (except the +12VSB) turn off. This signal is pulled to a standby voltage by a
pull-up resistor internal to the power supply. Refer to below table
