comes with one power supply module standard, and a second power supply
module for redundancy is optional.

NOTE The release latch, which is spring loaded, must be up to insert
the power cord. The power supply can not be removed from the
chassis with the power cord connected to the AC In connector.
The power cord must be removed before pushing down on the
release latch to free the power supply from the chassis.
Table 2-5. Power Supply LED Indicator Descriptions
Green LED Power Supply and NetServer Status
Steady Green This indicates the HP NetServer is powered up and operating
normally, or is in an ACPI suspend state.
Off This indicates the NetServer is powered off, the AC line cord
is unplugged, or the power supply has failed, which may
include a fan failure (turning too slowly). If a fan fails in one
of two supplies, the defective supply will continue to operate
until it reaches the thermal shutdown limit. The second power
supply (redundant power supply) will continue to operate
providing the necessary power. Refer to Chapter 12,
"Troubleshooting."
