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
(http://www.hp.com/go/rackandpower).
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
(http://www.hp.com/go/qs).
To obtain supported extension bars, contact an authorized reseller or see the HP website
(http://www.hp.com/go/rackandpower).
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 37)
