In Compaq 7000- and 9000-series racks, the 295363-xxx PDU series must be installed vertically
in the rack side panels to prevent interference with the server rack rails. Compaq Vertical Mount
PDU Bracket kits enable PDUs to be mounted vertically in the side compartments of 7000- and
9000-series racks. Compaq offers two Vertical Mount PDU Bracket kits:
• Compaq Vertical-Mount PDU Bracket (P/N 191265-B21): This kit includes eight brackets
that support four PDUs. This kit works best with low-voltage applications that use the power
cord included with the server.
• Compaq Vertical-Mount PDU Bracket with High Voltage Cables (P/N 166097-B21): This kit
includes eleven Y-cables and four brackets that support two PDUs. This kit works best with
high-voltage, high-current PDUs. Using the Y-cables enables each power outlet on the PDU
to supply power for two servers.
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- and low-voltage applications. The input current rating for a
ProLiant DL320 server is either 1 A at 200 to 240 volts or 2 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.
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 A at 200 volts.
24 A (PDU current rating) / 1 A (server total input current rating) = 24
PDU number 295363-003 can support a maximum of 24 servers at full server input current
ratings.

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

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 A at 100 volts.
24 A (PDU current rating) / 2 A (server total input current rating) = 12
PDU number 295363-001/291 can support a maximum of 12 servers at full server input
current ratings.

The ProLiant DL320 server does not support either a DC input power supply or a redundant
power supply. However, the power supply for this server automatically senses input voltage level.
