Table 4. PoE fault conditions and possible solutions
Possible SolutionPoE Fault Condition
The problem is most likely with the
attached PD. Check the condition
of the PD or restart the PD by
disconnecting and reconnecting
the PD.
A PoE-related short circuit occurred on the port.
The PoE power demand of the PD exceeded the maximum level that the
switch permits. The maximum level is 15.4W for a PoE connection or
30W for a PoE+ connection.
The PoE current on the port exceeded the classification limit of the PD.
Restart the switch to see if the
condition resolves itself.
The PoE voltage of the port is outside the range that the switch permits.
Enable or disable loop prevention
Loop prevention is enabled by default. When enabled and the switch detects a loop,
the LED or both LEDs of a port blink at a constant speed.
To enable loop detection:
1.
Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The
password is case-sensitive.
The HOME page displays.
4. Select DIAGNOSTICS > LOOP PREVENTION.
The LOOP PREVENTION page displays.
5. Click the toggle to enable or disable loop prevention. When enabled, the toggle
bar displays green.
6. Click the Apply button.
Your settings are saved.
