The illustration above shows an example of five HP 610 EPS units connected
in a closed-loop configuration.

Recommendations

The recommended installation is to connect all of the HP 610 EPS units into
one ring. The more units there are in a ring, the more efficient the redundancy.
For example, with three units in a ring the maximum total load for redundancy
is 2/3 of the maximum available power. However with five units in the ring,
the maximum total load is 4/5 of the maximum available power.
Limitations (Calculating required number of HP 610 EPS
units)
The total PoE load on all HP 610 EPS units must be less than the total power
available from N-1 of the power supplies, where N is the number of connected
units. The load on each HP 610 EPS must be no greater than the maximum
allowable for a single unit (850 W).
