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-8000GS 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.
