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 120Ωof UTP 5, 10Mbps is used 120Ωof UTP 3 ,4, 5.

RJ 45 port support automatic MDI/MDI-X operation. That can

connect the PC, Server, Converter and HUB. Pin 1, 2, 3, 4, 5, 6, 7,

8 Corresponding connections in MDI. 1→3, 2→6, 3→1, 4→7,

5→8, 6→2, 7→4, 8→5, are used as cross wiring in the MDI-X

port of Converter and HUB. In MDI/MDI-X, 100/1000Base-TX

PIN defines is as follows:

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).
