Power Cabling

Power Considerations for the HP NetServer LPr
The HP NetServer LPr supports four voltage ranges with typical values of: 100,
120, 208, or 230/240 VAC. Uniterruptible Power Supply (UPS) and Power
Distribution Unit (PDU) components are available to support these
configurations.
Power considerations for the HP NetServer LPr include:
Appropriately rated UPS models are available.
For 100-120 VAC, a single 16-amp PDU is available.
For 200/208 and 230/240 voltages, two PDU models (rated 10 A and
16 A) are available.
Multiple PDUs can be used in each rack enclosure, depending upon
requirements for power, current, and number of receptacles.
The appropriate power cord for each server is shipped according to
local requirements; refer to Table 3-1 for details.

100 - 120 VAC PDU Rack Power Configurations

The 100-120 VAC PDU power configurations are detailed in the
recommendations shown below and in Table 2-3 and Figure 2-11.
Connecting the PDU 100 - 120 VAC Configuration
The Power Distribution Unit plugs into the Uninterruptible Power Supply (UPS)
if one is present. The 100-120 volt PDU uses an E7802A detachable cord with a
NEMA 5-20P connector for connections to the receptacles on the right-hand side
(viewed from the rear) of the UPS. The power cord connects to the PDU through
a C19 connector.
CAUTION
It is not possible to plug one 16-amp, 100-120 VAC PDU into
another. This type of PDU must be plugged directly into a
UPS or site AC power circuit. Attempting to plug one of these
units into another could result in electrical failure or damage
to the equipment.
