Power supply input
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. Built-in
overcorrect protection, Reverse connection protection.
Voltage input range is 48VDC
terminal block defined as:
V1-
V1+
V2-
V2+
.
Important notice:
1. Power ON operation: first of all, insert power cable’s
terminal block into device’s power port, then insert power
supply plug into power source
2. Power OFF operation: First off all, unpin power plug, then
strike the terminal block, please take care of operation
sequence.

DIP Switch
Top panel provided 4 bits DIP switch to do function configure
ON to enable effective
, 1, 3 and 4 keep for future function.
2 is recovery default factory. Please power off and power on
when you change the status of DIP switch.
Relay connection
Relay access terminals in the top panel of the device.
Between the two terminal relay, as an open circuit state in
normal non alarm state, when there is any alarm information
to the closed state. The two terminal block connector are
used to detect both power failure and port failure. The
two
wires attached to the Fault contacts form an open circuit
when the device has lost power supply from one of the DC
power inputs or one of the ports is failure.
Console port
This series switch provided 1pcs procedure test port based
in serial port. It adopts RJ45 interface, located in top panel,
can configure related command through RJ45 to DB9
female cable.
Communication connector
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, 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:
