1. The current PoE outputs of all connected PDs exceed 240 Watts (for PoE models)
2. Power 1 or Power 2 was inactive
3. If anyone of all PoE ports exceeds 30 Watts (for PoE models)
4. Event happened by software setting
Relay is closed under the conditions below:
1. No event after reboot
2. No event after reset the switch
A connection of relay contact for fault alarm is shown below in

Figure 2.5: Wiring the relay contact for fault alarm
When the Ethernet switch is operating normally, the relay contact is a closed circuit. When the switch has any fault status
(PoE overload or power failure), the relay contact circuit is opened and the FAULT LED lights up. In addition, even after the
abnormal situation has been removed, the relay contact is still open and the FAULT LED remains active, unless using the
digital input to reset that. See the next section for information on Digital Input.
