Introducing the Switch
■ Power-over-Ethernet or PoE+ power - PoE+ technology allows IP
telephones, wireless LAN Access Points and other appliances to receive
power as well as data over existing LAN cabling, without needing to
modify the existing Ethernet infrastructure. The E2620-PoE+ Switches
are designed with an internal PoE+ power supply capable of providing
364 watts of PoE power (126 watts on the E2620-24-PPoE+. The PPoE+
(Partial PoE+) switch provides 24 Ethernet ports, 12 of which can supply
PoE+ power).
All of the Switch E2620-PoE+ ports can provide up to 30 watts (or 4 ports
at 30 watts, or 8 ports at 15.4 watts on the E2620-24-PPoE+) of PoE+ power
to connected devices. For further information regarding PoE/PoE+
power, see the
HP Power over Ethernet (PoE/PoE+) Planning and
Implementation Guide , which is on the HP Web site at
www.hp.com/
networking/support.
■ Redundant and External Power Supply Support - The E2620 non-
PoE+ and PPoE+ switches can be connected to an HP 600 Redundant and
External Power Supply (J8168A), hereafter referred to as the 600 RPS/
EPS, for RPS power only. As an RPS unit, the 600 RPS/EPS will provide
all the AC power necessary to keep the switch running should the switch
internal AC power supply fail. The 600 RPS/EPS can not be used for EPS
(PoE+) power for the E2620-PoE+ switches.
■ The E2620 PoE+ switches can be connected to an HP 620 Redundant and
External Power Supply (J8696A), hereafter referred to as the 620 RPS/
EPS, for RPS only. As an RPS unit, the 620 RPS/EPS will provide all the
AC power necessary to keep the switch running should the switch internal
AC power supply fail. The 620 RPS/EPS can not be used for EPS (PoE+)
power for the E2620-PoE+ switches.
■ Also, the E2620 PoE+ switches can be connected to an HP 630 Redundant
and/or External Power Supply (J9443A), hereafter referred to as the 630
RPS/EPS, and receive redundant power from that unit. As an EPS unit,
the 630 RPS/EPS can supply up to 398 watts of PoE power to the switch
if the internal PoE power supply of the switch should fail. When used with
the Switch E2620-48-PoE+, the additional EPS power can provide up to
30 watts per port for 48 ports. For further information regarding the RPS/
EPS PoE+ capabilities, see the
HP Power over Ethernet (PoE/PoE+)
Planning and Implementation Guide, or the HP Redundant and/or
External Power Supplies Installation and Getting Started Guide which
