Selecting Server Power Cords
The server power cord depends on the cable management system installed in the rack. Generally,
the sliding rail cable management system requires a power cord that is at least three feet longer
than the power cord used with a fixed cable management system. The additional three feet
provide enough slack for the power cord to route through the cable tension reel and the cable rack
bracket, enabling the power cord to operate smoothly with the sliding rails solution.
For high-voltage applications, Compaq recommends using high-voltage Y-cables. Y-cables have
a single cord section with an IEC connector that connects to the PDU, a dividing joint in the
center, and a dual cord section with IEC connectors that connect to the servers. One Y-cable
supplies power from the PDU for two ProLiant DL320 servers.
High-Voltage Y-Cables
The Vertical-Mount PDU Bracket with High Voltage Cables kit includes eleven Y-cables, each of
which is ten feet long. The single-cord PDU section is six feet long, and the dual-cord server
section is four feet long. See Table 7 for part numbers.

The IEC-to-IEC cables can be used either as individual
power cords for the server or to extend the length of the
high voltage Y-cables. The cables are available in six-,
eight-, and ten-foot lengths. The ProLiant DL320 ships
with one 10-ft IEC to IEC cable, part number 142257-
003.
Low-Voltage Power Cords
The power cord included with the North American and Japanese models of the ProLiant DL320
server can be used for low-voltage applications. Use a three- to five-feet long power cord with the
fixed-rail cable management solution or a six- to eight-feet long power cord with the sliding-rails
cable management solution. These lengths are optimal for PDUs installed in the rack side panels
with vertical-mount brackets.
Table 8 lists PDU configurations for 42U racks, Table 9 lists PDU configurations for 36U racks,
and Table 10 lists PDU configurations for 22U racks. The configurations in these tables refer to
racks that are fully populated with servers. Racks fully populated with servers use either an off-
rack console management system or a remote console management system. For an example
configuration of a rack using an in-rack console management system, see page 23.
