2.2 Wiring Power Inputs
DC Power Input
Follow below steps to wire the redundant DC power inputs.
1. Insert positive and negative wires into V+ and
V- contacts respectively of the terminal block
connector
2. Tighten the wire-clamp screws to prevent DC
wires from being loosened.
3. Power 1 and Power 2 support power
redundancy and polarity reverse protection
functions.
4. Positive and negative power system inputs are
both accepted, but Power 1 and Power 2 must apply the same mode.
Note 1: It is a good practice to turn off input and load power, and to unplug
power terminal block before making wire connections. Otherwise, your
screwdriver blade can inadvertently short your terminal connections to the
grounded enclosure.
Note 2: The range of the suitable DC electric wire is from 12 to 24 AWG.
Note 3: If the 2 power inputs are connected, the switch will be powered from the
highest connected voltage. The unit will alarm for loss of power, either POWER1
or POWER2.
Note 4: Use a UL Listed Power supply with output rating 12-48VDC, minimum
1 A.

7
2.3 Wiring Digital Output
The switch provides two digital outputs, also known as Relay Output. The relay
contacts are energized (open) for normal operation and will close for fault
conditions. The fault conditions include power failure, Ethernet port link break or
other pre-defined events which can be configured in management UI.
The default (without power) state of the Digital Output is normal CLOSE state.
The ON/OFF states are controlled by software configuration.
Wiring digital output is exactly the same as wiring power input introduced in
chapter 2.2.

2.4 Wiring Earth Ground
To ensure the system will not be damaged by noise or any electrical shock, we
suggest you to make exact connection with switch with Earth Ground.
For DC input, loosen the earth ground screw using a screw driver; then tighten
the screw after earth ground wire is connected.
2.5 Wiring Fast Ethernet Ports
The Fast Ethernet ports support 10Base-T and 100Base-TX, full or half duplex
modes. All the Fast Ethernet ports will auto-detect the signal from connected
devices to negotiate the link speed and duplex mode. Auto MDI/MDIX allows
users to connect another switch, hub or workstation without changing straight
through or crossover cables.
Note that crossover cables simply cross-connect the transmit lines at each end to
the received lines at the opposite end.
Straight-through Cabling Schematic
Cross-over Cabling Schematic
Note that Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ-45 connector. The
signals of these pins are converted by the automatic MDI-X function, as shown in
the table below:

3Preparation for Management
The switches provides both in-band and out-band configuration methods. You
can configure the switch via RS232 console cable if you don’t attach your admin
PC to your network, or if you lose network connection to your switch. This is
so-called out-band management. It wouldn’t be affected by network
connectivity.
The in-band management means you can remotely manage the switch via the
network. You can choose Telnet or Web-based management. You just need to
know the device’s IP address and you can remotely connect to its embedded
HTTP web pages or Telnet console.
Should you forget the IP address, you can use WeDashboard to discover the
device, check its IP address or assign new IP address. The WeDashboard can
discover the device across the subnet.
