●Connection of Cables
○Minimum Wire Gauge: 24AWG
●Relay Contact
Relay is opened if any event listed below happens:
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.
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.

LMX-1802G-M12-10G-SFP-67-110 Series - Hardware Manual - v1.0
●Digital Input (DI)
The digital input is used for monitoring two external events via an external voltage source. When the voltage level on
digital input pins changes from high voltage to low voltage, the DI function will be triggered. Table 2.7 is shown a detailed
specification of the digital input.

Table 2.7 - Specification of DI
As described in the Relay Contact section, if the fault status happens, you have to use DI function to reset the Fault LED,
so there are two DI functions this unit supports for manually reset or reboot the device, which is shown as follows.
1. When the trigger time < 4 seconds, the relay contact will be reset and the Fault LED light down.
2. When the trigger time > 4 seconds, the Ethernet switch will be rebooted.
2.12 Grounding Note
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground
connection from the ground screw to the grounding surface prior to connecting devices. The grounding screw symbol is
shown below in Figure 2.6.
Figure 2.6 - Grounding Screw Symbol

LMX-1802G-M12-10G-SFP-67-110 Series - Hardware Manual - v1.0
2.13 Bypass Function
This Ethernet switch supports bypass function by two Ethernet ports (P8 and P16). When one of the Ethernet switches
loses power, Ethernet ports (P8 and P16) will bypass the power lost Ethernet switch to prevent the network from
disconnecting.
Take Figure 2.7 for example, if Switch B has power failure, the bypass function will be activated automatically, and it will
bypass Switch B and bridge P8 to P16 of Switch B, so that the data transmission path (from Switch A to C) can remain
connected and unaffected.
