Installing Pdus - HP ProLiant DL360 Manual

hp ProLiant DL360 generation 3 server high-density deployment technical white paper

installing PDUs

PDU installation varies depending on the rack configuration, the number of servers deployed in
the rack, the selected type of PDU, as well as the voltage and current rating for each PDU. Refer
to the "high-voltage Y-cables" section for information about the Vertical-Mount PDU Bracket
kits available from HP. The installation card in the Vertical-Mount PDU Bracket kit contains
detailed instructions for installing the Vertical-Mount PDU Brackets on a PDU and in a rack.
positioning PDUs in 36U, 42U, and 47U racks
The position of the PDUs in the rack side panels varies depending on the rack size, the number of
servers deployed in the rack, and the cable management solution. As a rule, install PDUs from the
bottom to the top on the same side of the rack as the cable management solution (viewing the
rack from the front).
installing PDUs in a 36U, 42U, and 47U rack
Before installing PDUs in a 36, 42 or 47U rack, you might need to remove the center support
bracket and center it between the PDUs. Install the PDUs on the same side of the rack as the cable
management solution (viewing the rack from the front).
routing power cords
Use the following general procedures to route server power cords in 36, 42 or 47U racks.
IMPORTANT: When installing server power cords into the PDUs, ensure that the load is
balanced among the output circuit breakers.
high-voltage power cords
To route and connect high-voltage power cords:
IMPORTANT: Route and connect the high-voltage power cord to the PDU after the server is
installed.
1. Connect the power cord to the server and route it through the cable management system
with the other server cables.
2. Route the power cord inside the rear rack support to the PDU.
high-voltage Y-cables
To route high-voltage Y-cables:
1. Connect the single-cord section of the Y-cable to the PDU installed on the same side as
the cable management tray.
2. Align the Y-joint with the rear rack support and center it between the rack rails of the two
servers that the Y-cable supports.
3. Use two plastic tie wraps to secure the Y-joint to the rack support.
4. After installing the servers, connect the cables to the servers and route them through the
cable management system with the other server cables.
