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.

Installing a DC power supply

WARNING: To reduce the risk of electric shock, be sure that the cable grounding kit is properly installed and
connected to a suitable protective earth terminal before connecting the power source to the frame.
Two lugs ship in the kit with the -48V DC power supply. The two-hole lug specification is as follows:
• Width – 0.41 in (10.41 mm)
• Bolt hole size – 0.20 in (5.08 mm)
• Hole spacing – 0.63 in (16.00 mm)
Prerequisites
• Be sure the -48V DC power cables are installed. For more information, see the HPE Synergy 12000 Frame -48V DC
Power Cable Installation Instructions.
• Be sure that a ground connection to the HPE Synergy 12000 Frame has been properly installed. See Installing the DC
power grounding kit or the document that ships with the kit.
