The PoE threshold is a percentage of the total maximum PoE power on the device (400 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. 

To enable PoE for the device: 

1.

Click System > Power Over Ethernet. The Power Over Ethernet Page opens:

The Power Over Ethernet Page contains the following fields:

Unit Number — Indicates the stacking member for which the PoE information is displayed.

Power Status— Indicates if the port is enabled to work on PoE. The possible field values are: 

On — Indicates the device is delivering power to the interface.

Off — Indicates the device is not delivering power to the interface.

Test Fail —Indicates the powered device test has failed. For example, a port could not be enabled and 

cannot be used to deliver power to the powered device. 

Testing — Indicates the powered device is being tested. For example, a powered device is tested to 

confirm it is receiving power from the power supply. 

Searching — Indicates that the device is currently searching for a powered device. Searching is the 

default PoE operational status.
