Note 1: This PDU supports power from two different sources. If one power source fails, the PDU uses the alternate source.
Note 2: This PDU must be hard-wired to the power source by a certified electrician.
Note 3: This PDU is using the maximum rated power supply input and not the de-rated values.
Note 4: This PDU family is scheduled to be discontinued on December 31, 2002.
Figuring Type and Number of PDUs
The type and number of PDUs required to power a full rack of servers depends on each server’s
power requirement, the number of servers deployed in the rack, and the available power for the
servers.
Compaq PDUs support both high-voltage and low-voltage applications. The input current rating
for a ProLiant DL360 G2 server is either 1.48 A at 200 to 240 volts or 2.80 A at 100 to 120 volts.
To determine the number of servers supported by a PDU, divide the PDU’s current rating by the
server’s total input current rating.
IMPORTANT: The examples shown in the following sections use the maximum rating of the
power supply. They are for reference only.
Example
One high-voltage PDU (P/N 252663-D72) has a current rating of 24 A. The server has a total
input current rating of 1.48 A at 208 volts.
24 A (PDU current rating) / 1.48 A (server total input current rating) = 16
This PDU can support a maximum of 16 servers at full server input current ratings.
Example
One low-voltage PDU (P/N 252663-D71) has a current rating of 24 A. The server has a total
input current rating of 2.80 A at 110 volts.
24 A (PDU current rating) / 2.80 A (server total input current rating) = 8
This PDU can support a maximum of 8 servers at full server input current ratings.

Selecting Server Power Cords
The appropriate server power cord to use depends on the cable management system installed in
the rack. Generally, the sliding rail cable management system requires a power cord that is 1.8 m
(6 ft) in length. This length provides enough slack for the power cord to route through the cable
management arm.
