Setting the PoE Threshold
The PoE threshold is a percentage of the total maximum PoE power on
the switch, which for the AT-8524POE switch is 400 W. The switch sends
an SNMP trap to your management workstation and enters an event in the
event log whenever the total power requirements of the powered devices
exceed the threshold. At the default setting of 95%, the threshold is 380
W, which is 95% of 400 W. The threshold is adjustable. (For your
management workstations to receive traps from the switch, you must
configure SNMP on the switch by specifying the IP addresses of the
workstations.0
To configure the PoE threshold, perform the following procedure:
1. From the Home Page, select Configuration.
2. Select the System menu option.
3. Select the Power Over Ethernet tab.
Note
The Power Over Ethernet tab only appears for AT-8524POE
switches.
The Power Over Ethernet tab is shown in Figure 56.
