2. Installation
2.1 Unpacking
The product package contains:
The device
One product CD-ROM
2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the product, observe the
following precautions.
Do not service any product except as explained in your system documentation.
Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace
the part or contact your trained service provider:
The power cable, extension cable, or plug is damaged.
An object has fallen into the product.
The product has been exposed to water.
The product has been dropped or damaged.
The product does not operate correctly when you follow the operating instructions.
Do not push any objects into the openings of your system. Doing so can cause fire or electric
shock by shorting out interior components.
Operate the product only from the type of external power source indicated on the electrical ratings
label. If you are not sure of the type of power source required, consult your service provider or
local power company.

2.3 DIN-Rail Mounting
In the product package, a DIN-rail bracket is provided for mounting the switch in a industrial DIN-rail
enclosure.
The steps to mount the switch onto a DIN rail are:
1. Install the mounting bracket onto the switch unit as shown below:
2. Attach bracket to the lower edge of the DIN rail and push the unit upward a little bit until the bracket can
clamp on the upper edge of the DIN rail.
3. Clamp the unit to the DIN rail and make sure it is mounted securely.

on a plane surface securely. The mounting steps are:
1. Install the mounting bracket on the switch unit.
2. Screw the bracket on the switch unit.
3. Screw the switch unit on a panel. Three screw locations are shown below:

2.5 Applying Power
Power pins of the terminal block connector
1 2
Pin 
Vdc Positive () input terminal
Vdc Negative () input terminal
Pin 3 NC, Reserved
Any of the Vdc+/Vdc- pairs can be used to receive DC power from an external power system. Or, one can be
used to deliver the power received on another to next switch in cascading way.
Vdc Input specifications
Applications Power per PSE port DC working voltage
General - +8V ~ +60VDC
PoE 15.4W max. +45V ~ +57VDC (Typical 48V)
High power PoE (PoE+) 35W max. +45V ~ +57VDC (+52V up for 35W)
WARNING: The -48VDC power supply is not supported.
A 2P terminal plugs are provided together with the switch as shown below:
Power wires : 24 ~ 12AWG (IEC 0.5~2.5mm2)
-17-
Install the power source wires with the plug properly. Then, plug in input contacts. If cascading the power to
next switch device is needed, install the power wires and plug for another switch. Then, use another Vdc
contacts.

Note:
1. Only up to four device units can be cascaded to receive power from one main power input source.
2. The maximal length of the power wire is 1 meter.
2.6 Alarm Relay Output
Alarm relay output is provided for reporting failure events to a remote alarm relay monitoring system. The
replay output is provided with three contacts (support two logic types) in the terminal block connector next
Vdc interfaces.
Alarm Relay output pins and logic:
4 5
Pin NO NO
Alarm relay output, NO (Normal Open) contacts
Open: normal, Shorted: Alarm
5 6
Pin NC NC
Alarm relay output, NC (Normal Closed) contacts
Shorted: normal, Open: Alarm
Either pair can be used depending on the logic requirement for the relay monitoring system.
Use the provided 3P terminal plug for signal wiring and plug into the contacts.
Alarm Events
Input power failure
Specific port link down (The specific ports can be configured by software.)
Note: Be sure the voltage applied on the contacts is within the specification of 30VDC/1A max. or
120VAC/0.5A max.
2.7 Reset Button
-18-

The reset button is used to perform a reset to the switch. It is not used in normal cases and can be used for
diagnostic purpose. If any network hanging problem is suspected, it is useful to push the button to reset the
switch without turning off the power. Check whether the network is recovered.
The button can also be used to restore the software configuration settings to factory default values.
The operations are:
Operation Function
Press the button and release during switch operation Reset & boot up the switch. The behavior is
same as power boot procedure.
Press the button until MNGT-LED steady ON Boot & restore all factory default settings

2.8 Making UTP Connections
The 10/100/1000 RJ-45 copper ports support the following connection types and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3, 4, 5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters for all above
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable is connected, the ports can sense the receiving pair automatically and configure itself to match
the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the switch will sense the speed and use half duplex for the
connection.
Port Configuration Management
For making proper connection to an auto-negotiation incapable device, it is suggested to use port control
function via software management to set forced mode and specify speed and duplex mode which match the
configuration used by the connected device.
