Power Over Ethernet (PoE) Operation for the Series 2600-PWR Switches
Applicable Switch Models
Applicable Switch Models
The Power Over Ethernet (PoE) feature described in this chapter 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 408 watts of external
power by adding an HP ProCurve 600 Redundant and External Power Supply
(HP RPS/EPS; J8168A) or an HP ProCurve 610 External Power Supply.
Note 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.
