Communication connector
10/100BaseT(X) Ethernet port
The pinout of RJ45 port display as below, connect by UTP or STP.
The connect distance is no more than 100m. 100Mbps is used
120Ω of UTP 5; 10Mbps is used 120Ω of UTP 3, 4, 5.
RJ 45 port support automatic MDI/MDI-X operation. Can
connect the PC, Server, Converter and HUB .Pin 1,2,3,6
Corresponding connections in MDI. 1→3, 2→6, 3→1, 6→2 are
used as cross wiring in the MDI-X port of Converter and HUB.
10Base-T/100Base-TX are used in MDI/MDI-X, the define of Pin
in the table as below.

MDI (straight-through cable)
MDI-X (Cross over cable)
MDI/MDI-X auto connection makes switch easy to use for
customers without considering the type of network cable.
100Base-FX Fiber port
100Base-FX full-duplex SM or MM port, SC/ST/FC type .The
fiber port must be used in pair, TX (transmit) port connect remote
switch's RX (receive) port; RX (receive) port connect remote
switch's TX (transmit) port.
The optical fiber connection supports the line to instruct
enhance the reliability of network effectively
Suppose: If you make your own cable, we suggest labeling the
two sides of the same line with the same letter (A-to-A and
B-to-B, shown as below, or A1-to-A2 and B1-to-B2).

1000SFP fiber port(mini-GBIC)
1000BaseSFP fiber port adopts gigabit mini-GBIC transmission,
can choice different SFP module according to different transfer
distance. Fiber interface must use for pair, TX port is transmit side,
must connect to RX (receive side). The fiber interface support loss
line indicator.
Suppose: If you make your own cable, we suggest labeling the
two sides of the same line with the same letter (A-to-A and
B-to-B, shown as below, or A1-to-A2 and B1-to-B2).
