PDU support
The HP ProLiant s6500 Chassis uses PDUs to provide power to the servers. Many PDU configurations are
possible. For rack-mounting instructions and locations, see the documentation provided with the PDU.
HP recommends using fixed-cord mPDUs to supply power to components in the rack.
Depending on the server power supply configuration, each mPDU (at high line voltage) can support the
following:
•
Up to 10 servers (with two power supplies each)
•
Up to 20 servers (with one power supply each)
For a list of supported mPDUs, see the product QuickSpecs on the HP website (
http://www.hp.com/go/qs
).
To obtain supported mPDUs, contact an authorized reseller or see the HP website
(

).
Extension bar support
To distribute power from the PDUs, use the appropriate type of cables and power connector to connect to the
server power supplies.
For servers with 750-W power supplies, HP recommends using fixed-cord extension bars with mPDUs.
An HP fixed-cord extension bar has four cords with power connectors. Depending on the server power
supply configuration, each extension bar can support the following:
•
Up to two servers (with two power supplies)
•
Up to four servers (with one power supply)
For a fully configured 42U rack with two switches and 20 servers with 2 power supplies, 11 extension bars
are required.
For a list of supported extension bars, see the product QuickSpecs on the HP website
(

).
To obtain supported extension bars, contact an authorized reseller or see the HP website

Power cabling configurations
Many power cabling configurations are possible, including the following examples.
In some installations, multiple racks are installed in close proximity to each other. Mounting the PDUs in a 0-U
configuration is impractical. In these instances, the following examples apply:
•
Bottom-mounted mPDU and fixed-cord extension bar configuration (on page
39
)
•
Power cabling with Y-cables and bottom-mounted PDU (on page
40
)
For single racks (including separated racks), possible power cabling configurations include the following:
•
mPDU and fixed-cord extension bar configuration (on page
34
)
•
Power cabling with extension bars (on page
35
)
•
Power cabling with Y-cables (on page
