Introduction
PoE Capabilities of the HP Products
HP ProCurve 3500-PoE Switches
The HP ProCurve Switch 3500-48G-PoE (J9473A), has 44 Integrated PoE auto-
sensing 10/100 Base-T RJ-45 ports and four ports of Gigabit dual-personality
Uplink ports, either RJ-45 or SFP.
The HP ProCurve Switch 3500-24G-PoE (J9471A), has 20 Integrated PoE auto-
sensing 10/100 Base-T RJ-45 ports with four ports of Gigabit dual-personality
Uplink ports, either RJ-45 or SFP.
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 Base-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.
Power Redundancy for the 3500 Switches
The internal power supply in these switches provides both the 12V (RPS) and
50V (EPS) circuits. If the 50V portion of the power supply fails, it will only shut
down the PoE connections. However, if the 12V portion of the power supply
fails, it will shut down the entire switch. Therefore it is important to provide
a redundant power supply for both the 12V and 50V circuits. It is recommended
that both EPS and RPS be connected to provide full redundancy.
