Introducing the HP 610 Redundant and
External Power Supplies
The HP 610 External Power Supply can supply additional power for PoE
switches and backup PoE power to other HP 610 units. It does not supply
system power.
Throughout this manual, this unit will be abbreviated as the HP 610 EPS.
The HP 610 EPS has four EPS ports that provide PoE power for up to four HP
PoE switches. The HP 610 EPS also has two backup ports for supporting
backup PoE power to other HP 610 EPS units connected in a group. There are
two supported topologies, a string (daisy-chain) and a ring (closed-loop).
This chapter describes the HP 610 EPS including:
■ front of the unit (page 2-2)
■ back of the unit (page 2-4)
■ EPS port operation (page 2-5)
■ backup power port operation (page 2-6)
■ supported switches (page 2-6)
