The switch support redundant DC power input, which provides
two terminal blocks for PWR1 and PWR2 input. Voltage input
range is 12
～
48VDC. The redundant power can be used
independently. PWR1 and PWR2 can supply power at the same
time, once either of these two powers fails, another power can
acts as backup automatically to ensure reliability of the network.
It also supports reverse polarity connection.

10/100BaseT(X) Ethernet port
The pinout define of RJ45 port display as below, connect by UTP
or STP. The connect distance is no more than 100m. 100Mbps is
used 120
Ω
of UTP 5, 10Mbps is used 120
Ω
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

10/100Base-T(X) MDI (straight-through cable)
10/100Base-T(X) MDI-X (Cross over cable)
MDI/MDI-X auto connection makes switch easy to use for
customers without considering the type of network cable.
1000Base SFP fiber port(mini-GBIC)
1000Base-FX SFP 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).
