Server System H2000WP Family TPS Power Sub-System
3.4.1 1200W CRPS Cold Redundancy
If the output power is less than 480W (40%), the Cold redundant function is enabled. You will
see one PSU working normally. The second PSU will be in CR mode. The Power Supply LED
will be blinking green.

3.4.2 1600W CRPS Cold Redundancy
If the output power is less than 640W (40%), the Cold redundant function is enabled. You will
see one PSU working normal. The second PSU will be in CR mode. The Power Supply LED will
be blinking green.

Optimal Redundant
Mode
1. With BIOS setting “server
management - shutdown policy” set
to “disable”, all
nodes in the system
may be throttled to maintain
power. This may cause lower
performance.
2. With BIOS “server management--
shutdown policy” set to “enable”,
Nodes 3 and 4 will shut down while
Nodes 1 and 2 keep running without
throttling. Node 1 and Node 2 will
have no performance loss.
>1800W >2160W Non Redundant Mode
All nodes in the system may
shutdown.
3.5 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: Signal
#
= low true
