Introduction
PoE Capabilities of the HP Products
The HP ProCurve 3500-PoE Switches can be connected to a 620 RPS/EPS
(J8696A) and receive full redundant power from the RPS part of the unit for
switch operation if the internal power supply in the switch fails. If two
switches are connected to the RPS ports and both switches lose power at the
same time, they both receive redundant power. The 620 RPS/EPS unit can
provide all the power necessary to keep two switches running.
If maximum PoE power is to be used on all 48 ports, you must connect an HP
620 RPS/EPS, since the internal power supply only has enough power to
supply 24 ports with maximum wattage. In this case, there is no redundancy.
HP ProCurve 3500yl-PWR Switches
The HP ProCurve Switch 3500yl-48G-PWR (J8693A), has 44 Integrated PoE
auto-sensing 10/100/1000Base-T RJ-45 ports with four dual-personality Gigabit
Uplink ports.
The HP ProCurve Switch 3500yl-24G-PWR (J8692A), has 20 Integrated PoE
auto-sensing 10/100/1000Base-T RJ-45 ports with four dual-personality Gigabit
Uplink ports.
These switches also support some pre-standard PoE devices. For a list of these
devices, see the FAQs for your switch model. This feature is the default and
you must disable it if you do not want to use it. For example:
ProCurve(config)# no power pre-std-detect
For more information, refer to the Management and Configuration Guide
for your switch at www.hp.com/networking/support.
The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45
or mini-GBIC connectivity. The mini-GBIC ports do not support PoE. If any of
the mini-GBIC ports are used the corresponding RJ-45 port will not be supplied
with PoE power.
