ProCurve 620 Redundant/
External Power Supply
The ProCurve 620 Redundant/External
Power Supply provides RPS and EPS power
individually to two ProCurve 3500 switches or
RPS to two ProCurve 6200 or ProCurve 2900
switches. The ProCurve 620 does not support
the ProCurve 8200 or 5400 switches.
RPS power: Connecting the RPS provides full
redundancy for the connected switch’s system
power.
EPS power: The ProCurve 620 supply provides
398 W of additional PoE power to each of two
connected ProCurve 3500 switches. For a
ProCurve Switch 3500-24, the internal power
supply can power all 24 ports at 15.4 W for
PoE. The additional power available from the
ProCurve 620 provides full redundancy for the
PoE power.
If the ProCurve 620 is connected to a ProCurve
Switch 3500-48, it allows all 48 ports to run at
the full 15.4 W simultaneously but with no
PoE power redundancy. The additional PoE
power from the ProCurve 620 could be used to
provide full PoE power redundancy for 24 of
the 48 ports, if that is needed, rather than
additional power for the extra ports.
ProCurve Switch zl Power
Supply Shelf
The ProCurve Switch zl Power Supply Shelf
(J8714A) provides two additional power supply
bays for connection to one or two zl switches.
Used for providing extra EPS (PoE) power to the
zl switch, the extra PoE power can be used to
power additional PDs beyond what can be
powered by the internal switch supplies or,
more commonly, to provide for larger
redundant PoE power environments, such as
large VoIP installations.
The Power Shelf accepts the same power
supplies available for the zl switches and
connects to the switches via 2 m EPS cables
included with the Power Shelf. The extra PoE
power available via the Power Shelf is
determined by the power supplies installed in
the Shelf. See the Power Shelf data sheet for
more details.
