Chapter 4: Power over Ethernet
The A
vaya Ethernet Routing Switch 4500 Series 4548GT-PWR and the 4526GTX-PWR (PoE switches)
provide IEEE 802.3af-compliant power or PoE on all 10/100/1000 RJ-45 ports.
The Avaya Ethernet Routing Switch 4500 Series 4526T-PWR and the 4550T-PWR (PoE switches) provide
IEEE 802.3af-compliant power or PoE on all 10/100 RJ-45 ports.
PoE is based on the IEEE 802.3af standard.
PoE is the ability of the 4550T-PWR,4548GT-PWR,4526T-PWR and 4526GTX-PWR to power network
devices over the Ethernet cable. These devices include IP Phones, wireless LAN access points, security
cameras, and access control points.
For more information about power supplies, see Avaya Ethernet Routing Switch 4500 Series Installation
(NN47205-301).
You can configure PoE from ACLI, SNMP, Enterprise Device Manager (EDM). For details, see the following
sections.

To configure PoE, see the following procedures:
• Configuring PoE using ACLI on page 125
• PoE configuration for switch ports using EDM on page 234

PoE overview
The A
vaya Ethernet Routing Switch 4500 Series 4550T-PWR, 4548GT-PWR,4526T-PWR and
4526GTX-PWR are ideal to use with Avaya Business Communication Manager system, IP
phones, hubs, and wireless access points. You can use these switches with all network
devices.
By using the Avaya Ethernet Routing Switch 4500 Series 4550T-PWR,4548GT-PWR, 4526T-
PWR and 4526GTX-PWR you can plug any IEEE802.3af-compliant powered device into a
front-panel port and receive power in that port. Data also can pass simultaneously on that port.
This capability is called PoE.
For more information about PoE and power supplies, see Avaya Ethernet Routing Switch 4500
Series Installation (NN47205-301).
The IEEE 802.3af draft standard regulates a maximum of 15.4 W of power for each port; that
is, a power device cannot request more than 15.4 W of power. As different network devices
