The E620 Redundant/External Power Supply provides redundant system power and/or an extra 398 W of Power over Ethernet (PoE) power for each of two supported switches simultaneously. Ideally suited for Voice over IP (VoIP) environments, the E620 provides the RPS and extra PoE power needed in many other common customer environments where high power availability is desired. Switchover from a failed internal power supply to the 620 is seamless and immediate. In addition, the 620 can protect against a single power main failure by being connected to a different power main than the switch. The 620 supports the HP E3500 Series, as well as E6200 switches.

- Independent RPS and EPS ports: two RPS ports provide system power for up to two switches simultaneously and two EPS ports provide PoE power for up to two switches simultaneously. Supports a number of HP E-Series stackable switches: Redundant power supply (RPS): provides full redundant system power (RPS) support for the HP E2900 Series, E2910 Series, and E3500 yl Series, as well as E6200 yl switches. External power supply (EPS): provides an additional 398 W of PoE (EPS) power to the HP E3500 yl Series. Cables included: includes four 2-meter RPS/EPS cables; cables can be used to carry RPS power or EPS power to the connected switch; no extra cables are needed for a complete solution.
- Independent RPS and EPS ports: two RPS ports provide system power for up to two switches simultaneously and two EPS ports provide PoE power for up to two switches simultaneously. Supports a number of ProCurve stackable switches: Redundant power supply (RPS): provides full redundant system power (RPS) support for the HP ProCurve Switch 2900 Series and 3500yl Series, as well as 6200yl switches. External power supply (EPS): provides an additional 398 W of PoE (EPS) power to the ProCurve Switch 3500yl Series. Cables included: includes four 2-meter RPS/EPS cables; cables can be used to carry RPS po
