one end of the fibers.
Caution:
The device uses laser to transmit signals in fibers. The laser meets the requirements of level 1 laser
products. Routine operation is not harmful to your eyes, but do not look directly at the fiber port when
the device is powered on.
If the defined transmission distance of an SFP module is longer than 60km, do not use a short fiber
(<20km) for connection. If such a short fiber is used, the module will be burned.

4.3 Grounding
Grounding protects the switch from lightning and interference. Therefore, you must ground the
switch properly. You need to ground the switch before it is powered on and disconnect the
grounding cable after the switch is powered off.
The switch provides a grounding screw on the top panel for chassis grounding. After crimping one
end of the grounding cable to a cold pressed terminal, secure the end to the grounding screw and
connect the other end to the earth firmly.
