The switch top panel provided 4 bit power supply input terminal
block, support DC input. DC power supply input supported
redundancy function, provided PWR1 and PWR2 power input,
can use for single, and can connect 2 separately power supply
system, use 1 pair terminal block connect the device at the same
time. If one of the power systems broke, the device can work
un-interruptible.

10/100/1000BaseT(X) Ethernet port
The pinout of RJ45 port display as below, connect by UTP or STP.
The connect distance is no more than 100m. 1000Mbps is used
120Ω of UTP 5e; 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. That can
connect the PC, Server, Converter and HUB. Pin 1, 2, 3, 4, 5, 6, 7,

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:
