Power supply configurations

Sufficient power supplies must be installed to support the installed devices and interconnect modules. Power estimates for HPE Synergy can be provided using either the HPE Synergy Planning Tool or the HPE Power Advisor. For more information about the HPE Power Advisor or the HPE Synergy Planning Tool, see the Data Center Infrastructure Advisor page (https://dcia.itcs.hpe.com/).

The number of supported power supplies in the frame range from a minimum of two to a maximum of six power supplies. There are no power supply bay placement restrictions of power supplies in the frame. However, for best cooling and power distribution, Hewlett Packard Enterprise recommends the following best practice for power supply usage.

NOTE: The default power mode is Redundant power feed mode.

If an odd number of power supplies are installed in a

frame

that is configured for redundant power feed mode, all power supplies are providing power to the frame, but the capacity of the odd power supply is not used to determine the overall power capacity of the

frame

.

To enhance cooling, populate all power supply bays with either a power supply blank or a power supply.

Power supply configuration recommendations for the frame do not depend on the type of power supply being used. However, all power supplies must be of the same type. Mixed-type power supply configurations are not supported.
