The HP ProCurve 600 Redundant and External Power Supply is a dual-mode power supply that can supply backup power to so equipped HP ProCurve switches and additional power for Power over Ethernet (PoE) capable switches.

The HP ProCurve 610 External Power Supply can supply additional power for PoE capable switches and backup power to other HP ProCurve 610 units.

Throughout this manual, these units will be abbreviated as the HP 600 RPS/ EPS and HP 610 EPS.

The HP 600 RPS/EPS has six redundant power supply (RPS) ports supporting backup power to six supported HP ProCurve switches. The HP 600 RPS/EPS also has two external power supply (EPS) ports that provide PoE power for up to two HP PoE switches.

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 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).
