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 hardwired to the power source by a certified electrician.
Note 3: This PDU is using the maximum rated power supply input and not the derated values.
Note 3: This PDU to discontinue 1H2003.
Figuring Type and Number of PDUs
Comment – make sure all examples use the new Modular PDUs, 252663-xxx
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.
HP PDUs support both high-voltage and low-voltage applications. The input current rating for a
ProLiant DL320 Generation 2 server is either 1.38 A at 200 to 240 V or 2.77 A at 100 to 120 V.
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
PDU number 295363-003 is a high-voltage PDU with a current rating of 24 A. The server has
a total input current rating of 1.38 A at 200 V.
24 A (PDU current rating)/1.38 A (server total input current rating) = 17.4
PDU number 295363-003 can support a maximum of 17 servers at full server input current
ratings.

America and International Use, (NA CPQ # 295363-002; INT'L CPQ # 295363-B31)” website:

Example
PDU number 295363-001/291 is a low-voltage PDU with a current rating of 24 A. The server
has a total input current rating of 2.77A at 100 V.
