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.

How to Connect the SFP Electrical Module
Insert the SFP electrical module into the SFP slot in the switch, and then insert the RJ45 connector
of the twisted pair into the SFP module.

4.4 1000Base-X, 10/100/1000Base-T(X) Combo Port
1000Base-X, 10/100/1000Base-T(X) Combo port (Combo port for short) consists of one gigabit
SFP slot and one 10/100/1000Base-T(X) Ethernet port. Only one of the two can work at a time. The
gigabit SFP slot takes preference over the 10/100/1000Base-T(X) Ethernet port, that is, if both the
gigabit SFP slot and 10/100/1000Base-T(X) Ethernet port are connected, the gigabit SFP slot
works while 10/100/1000Base-T(X) Ethernet port stops working automatically. For details about the
gigabit SFP slot, see section 4.3; for details about the 10/100/1000Base-T(X) Ethernet port, see
section 4.1.1.
