power input parts, R+ and R- are in the middle of the relay alarm
output section. It is used to detect both power failure and port
failure. The open circuit state in normal non alarm state, when
there is any alarm information to the closed state. This series of
switch device have 2 relay alarm output, external alarm lights or
alarm buzzer or external switch signal acquisition device in order
to timely notify operators when an alarm occurs.
【
Console port

This series product provided 1pcs procedure test port based in
serial port. It adopts RJ45 interface, located in top panel, can
configure the CLI command through RJ45 to DB9 female cable.

10/100/1000BaseT(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. 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:

MDI/MDI-X auto connection makes switch easy to use for
customers without considering the type of network cable.
1000Base SFP /10GbE SFP+ fiber port
1000BaseSFP and 10GbE SFP+ optical fiber interface is used are
SFP optical module communication through optical fiber
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).
