Configuring Power Over Ethernet

Chapter 14.Configuring Power Over Ethernet

This section describes configuring Power over Ethernet (PoE) for an AT-S9 device. PoE only applies to the

supporting AT-8000S devices.

Power-over-Ethernet (PoE) provides power to devices over existing LAN cabling, without updating or modifying

the network infrastructure. Power-over-Ethernet removes the necessity of placing network devices next to power

sources. Power-over-Ethernet can be used in the following applications:

• IP phones

• Wireless Access Points

• IP gateways

• PDAs

• Audio and video remote monitoring

Powered Devices are devices which receive power from the device power supplies, for example IP phones.

Powered Devices are connected to the device via Ethernet ports.

The PoE threshold is a percentage of the total maximum PoE power on the device (375 W). If the total power

requirements of the powered devices exceed this threshold, the device sends an SNMP trap to the management

workstation and enters an event in the event log. The threshold is adjustable. For management workstations to

receive traps from the device, configure SNMP on the device by specifying the IP addresses of the workstations.

The Power Over Ethernet Page contains system PoE information for enabling PoE on the device, monitoring the

current power usage, and enabling PoE traps.
