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
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
