The IES205G switch top panel provides 3-pin power supply
input terminal block and supports DC input. Voltage input
range is 12～48VDC (terminal block defined as: V+, V-).
The power supply has a nonpolar, reverse connection
protection function when the device power supply positive
and negative reverse connection can still work properly.
Important notice:
1. Power ON operation: insert power cable's terminal block
into device's power port, and then connect power supply
plug to a power source.
2. Power OFF operation: unpin power plug, and then
disconnect the terminal block, please note operation
sequence.
【Communication Connector】
10/100/1000Base-T(X) Ethernet port
The pinout of RJ45 port is displayed as follows and is
connected to UTP or STP. The connection distance is no
more than 100m. 1000Mbps uses 120Ω of UTP CAT5e or
CAT6; 100Mbps uses 120Ω of UTP CAT5; 10Mbps uses
120Ω of UTP CAT3, CAT4, and CAT5.
RJ45 port supports 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-T(X) PIN is defined as follows:
