100/120V Pdu Rack Power Configurations - HP D7171A - NetServer - LPr Manual

Chapter 2
For 120 VAC, a 16-amp Power Distribution Unit (PDU) is available
For both 200/208 and 230/240 voltages, two Power Distribution Unit
(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

100/120V PDU Rack Power Configurations

The 120 VAC PDU power configurations are detailed in the recommendations
shown below and in Table 2-4 and Figure 2-8.
NOTE
100 VAC configurations are the same as 120 VAC, except for
the UPS and the cable which connects the PDU to it. See
Table 3-1 and the notes which accompany it.
Connecting the PDU 120 VAC Configuration
The Power Distribution Unit (PDU) plugs into the Uninterruptible Power Supply
(UPS) if one is present. The 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. It connects to the PDU through a C19
connector.
CAUTION
It is not possible to plug one 16-amp, 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.
Alternate 120 VAC Power Configurations
When the 120 VAC PDU is used without a UPS in the rack, the PDU needs one
branch circuit with a NEMA 5-20 receptacle.
If neither a UPS nor a PDU are used in the 120 VAC case, plug the components
directly into NEMA 5-15 receptacles using the line cords supplied.
