2.5 Relay Contact Alarm Warning
2-pin 1*24VDC@1A resistive normal open on 6-pin terminal block.
The relay contact alarm will be triggered when any one of the listed events occurs.
Key trigger event 1: Power 1 or Power 2 is inactive
Key trigger event 2: PoE total loading > 100% PoE output budget (Only support in PoE model)
Key trigger event 3: PoE over current per port (Only support in PoE model)
Key trigger event 4: Cable short per port
Key trigger event 5: One of the channels in Dual PD fail
* Note:
When the relay is triggered because of event 2~5, the relay contact alarm will update the status every 30 seconds. If there
is no event happening for 30 seconds, the relay contact alarm will be turned off. If the user disables the failed PoE port by
removing the cable or DIP switch manually, the relay will be recovered immediately.
2.6 Ethernet Ports
●
RJ45 Ports
RJ45 Ports (Auto MDI/MDI-X):
The RJ45 ports are auto-sensing for 10Base-T, 100Base-TX, or 1000Base-T connections.
Auto MDI means that the switch can connect to another switch or workstation without changing the straight-through or
crossover cabling. See the figures below for straight-through and crossover cabling schematics.
