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 blow in Figure 2.4.

Caution:
Using a shielded cable achieves better electromagnetic compatibility.
Attention:
L'utilisation d'un câble blindé permet une meilleure compatibilité
électromagnétique.
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 2.5 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.

Reset to Default
Please perform the below steps to reset the switch to factory default setting.
Step 1.
Reverse the Tx & Rx of the Console Cable and plug it into the console port.
Step 2.
Restart the power.
Step 3.
The switch will start rebooting with the port LEDs flashing.
Step 4.
When the Status LED turns into Green, the process is completed.
Step 5.
Remove the reversed console cable.
