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

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)

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).

Installation
Before installation, confirm that the work environment meet the
installation require, including the power needs and abundant
space. Whether it is close to the connection equipment and other
equipments are prepared or not.
1. Avoid in the sunshine, keep away from the heat fountainhead or
the area where in intense EMI.
2. Examine the cables and plugs that installation requirements.
3. Examine whether the cables be seemly or not (less than 100m)
according to reasonable scheme.
4. Power: support 12 ~ 48VDC power supply
