Applicable Switch Models
The Power Over Ethernet (PoE) feature described in this supplement operates
on these switches:
■
HP ProCurve Switch 2626-PWR (J8164A)
■
HP ProCurve Switch 2650-PWR (J8165A)
Introduction
PoE technology allows IP telephones, wireless LAN access points, and other
appliances to receive power and transfer data over existing LAN cabling.
General Operation
The Switch 2626-PWR and 2650--PWR provision their 10/100Base-TX ports
with 406 watts of power for PoE applications compatible with the IEEE
802.3af standard. On the Switch 2650-PWR, you can optionally provision ports
1-24 with 406 watts of internal power and ports 25-48 with 368 watts of external
power by adding an HP ProCurve 600 Redundant and External Power Supply
(HP RPS/EPS; J8168A).
N o t e �
The switches support the normal operation of non-PoE devices on ports
configured for PoE operation.
Regarding Cat-5 cabling for PoE, the 802.af standard allows either the spare
pair or the data pair for PoE power transmission. The Switch 2600-PWR series
devices supply PoE power over the data pair.
Using the commands described in this chapter, you can:
■
Configure a power threshold for SNMP and Event Log reporting of
PoE consumption on the switch.
■
Specify the priority you want the switch to use for provisioning PoE
in the event that the switch’s PoE resources become oversubscribed.
