Power Over Ethernet (PoE) Operation
Overview
Related Publications
This chapter introduces general PoE operation, PoE configuration and
monitoring commands, and event log messages related to PoE operation on
the ProCurve Series 2610-PWR switches. The following two manuals provide
further information:
■
For information on installation, refer to the
ProCurve Series 2610
Switches Installation and Reference Guide provided with the switch.
■ To help you plan and implement a PoE system in your network, refer
to the
PoE Planning and Implementation Guide , which is available
from the ProCurve website at www.procurve.com . (Click on Technical

Terminology
The following PoE terms and concepts are used in this manual.
Term Use in this Manual
active PoE port A PoE-enabled port connected to a PD requesting power.
priority class Refers to the type of power prioritization where the switch uses Low (the default), High, and
Critical priority assignments to determine which groups of ports will receive power. Note that
power priority rules apply only if PoE provisioning on the switch becomes oversubscribed.
EPS External Power Supply; for example, a ProCurve 600 RPS/EPS or a ProCurve 610 EPS. An EPS
device provides power to provision PoE ports on a switch. See also “RPS” below.
MPS Maintenance Power Signature; the signal a PD sends to the switch to indicate that the PD is
connected and requires power. Refer to Figure 11-4 on page 14.
PD Powered Device. A device that receives power through a direct connection to a 10/100
Base-TX PoE RJ-45 port on the switch. Examples of PDs include Voice-over-IP (VoIP)
telephones, wireless access points, and remote video cameras.
port-number
priority Refers to the type of power prioritization where, within a priority class, the switch assigns
the highest priority to the lowest-numbered port, the second-highest priority to the second
lowest-numbered port, and so-on. Note that power priority rules apply only if PoE provisioning
on the switch becomes oversubscribed.
RPS Redundant Power Supply; for example, a ProCurve 600 RPS/EPS. An RPS device provides
power to a switch if the switch’s internal power supply fails. RPS power does not provision
PoE ports on a switch whose internal power supply has failed. See also “EPS” above.
