Introduction
Overview
Introduction
It does this by applying a small current-limited voltage to the cable and checks
for the presence of a 25k ohm resistor in the remote device. Only if the resistor
is present, will the full wattage be applied, but this is still current-limited to
prevent damage to cables and equipment in fault conditions.
The PD must continue to draw a minimum current. If it does not (for example,
when the device is unplugged) then the PSE removes the power and the
discovery process begins again.
PoE Capabilities of the Products
The ProCurve PoE switch devices are multiport switches that can be used to
build high-performance switched workgroup networks with PoE. These
switches are store-and-forward devices that offer low latency for high-speed
networking. The ProCurve PoE switch devices are designed to support
Redundant Power Supply and Power over Ethernet (PoE) technologies.
■ The ProCurve Switch 3500yl-48G-PWR (J8693A), has 48 Integrated PoE
auto-sensing 10/100/1000Base-T RJ-45 ports with four dual-personality
Gigabit Uplink ports.
■ The ProCurve Switch 3500yl-24G-PWR (J8692A), has 24 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. Refer to the Management and
Configuration Guide which is on the ProCurve Web site, www.procurve.com.
