Introducing the HP 610 Redundant and External Power Supplies

EPS Backup Power Port Operation

Up to five HP 610 EPS units can be connected together through EPS backup

power cables, but the EPS backup power ports can provide redundant PoE

power to only one unit whose internal PoE power fails. The active units can

provide up to 850 W of power to a single failed HP 610 EPS.

The HP 610 EPS is able to detect other units connected to the backup power

ports and also the status of their primary AC power supply. The HP 610 EPS

supports a hot-plug feature where units can be connected or disconnected to

the backup power ports without causing any disruption to the units in the

backup power group.

Note HP recommends connecting the “IN” connector first, then connect the “OUT”

connector. Connecting in this manner ensures there is no voltage on the cable.
