The servers are shipped with grounding-type (three-wire) power cords. Always
connect the cords into grounded power outlets.
Caution – The server is designed to work with power systems having a grounded
neutral conductor. Do not connect the equipment into any other type of power
system. Contact your facilities manager or a qualified electrician to determine what
type of power is supplied to your building.
1. Arrange the layout of all cables outside the system and secure the cables in
place to prevent them from being damaged. Refer to “Facility Power
Requirements and Characteristics” on page 2-4 for diagrams showing cable
connections.
Note – It is the installer’s responsibility to ensure that the facility power source has
sufficient electrical power and redundancy to handle the required installation.
2. Connect the power cords to the input power source.
For redundancy in case of power source failure PSU0 and PSU2 should be
powered from AC GRID A and PSU1 and PSU3 should be powered from AC
GRID B.
Note – Use 200V when connecting cords for redundancy, 100V is not supported.
3. Make certain the power cords are tightly fastened.
Note – The power cords and infiniband cables should hang loosely in a service loop
behind the server or the cable management arm may not be able to fully retract.
