Addendum to D Class Enterprise Servers System Installation Guide
DC Power Supply
DC Power Supply
The HP 9000
Series 800t
D Class Server contains a NEBS-compatible direct
current (DC) power supply, rather than the alternating current (AC) power
supply furnished with the standard HP 9000 D Class computer. This
switching power supply is designed to work on DC by replacing the AC
input module with a DC-to-DC converter module.
This DC power supply directly replaces the standard AC supply for the
purpose of operating this computer from a telephone central office negative
48 volt battery or negative 60 volt battery input.
WARNING: A shock hazard exists! Do not attempt to power-up the power supply system
outside the computer system chassis. The power supply requires a load and
other enabling signals to operate properly.
This DC power option provides a D Class computer server compatible to
NEBS requirements for operation in a Central Office environment where
equipment is powered from 48VDC batteries.
The power supply also provides alarm outputs in the form of relay contact
closures to indicate a power supply failure. An additional feature provides a
remote control input, which can be used to turn off the power supply for the
purposes of resetting the computer system.
Connections
The Z7634-60001 DC Power Supply comes with a 9-pin Universal Mate-N-
Lock connector for power, alarm, and control circuits. A mating 9-pin plug
with a 15-foot cable is supplied with the unit. The other end of the cable is
bare wire to be connected to the battery plant on the site.
