-15-
2.5 Applying Power
The switch provides two types of power interfaces, terminal block and DC power jack for receiving DC
power input from external power supply.
Using Terminal Blocks
Either DC1 interface or DC2 interface can be used to receive DC power from an external power
system. Or, DC2 also can be used to deliver the power received on DC1 to next switch in cascading
way.
DC1 + Vdc Positive (+) terminal
DC1 - VdcNegative (-) terminal
DC2 + Vdc Positive (+) terminal
DC2 - VdcNegative (-) terminal
* Working Vdc for general application: +6.5V ~ +54VDC
* Working Vdc for PoE application: +44V ~ +54VDC (Typ. 48V)
Three 2Pterminal plugs are provided together with the switch. Two of the three plugs are used forDC1
andDC2 interfaces respectively. The plug is shown below:
Power wires : 24 ~ 12AWG(IEC 0.5~2.5mm2)
Install the power source wires with the plug properly. Then, plug in DC1 contacts. If cascading the
power to next switch device is needed, install the power wires and plug for another switch. Then, use
DC2 contacts.
Note: Only up to four device units can be cascaded to receive power from
one main power input source.

-16-
Using DC Power Jack
When an external power system is not available, the switch provides aDC jack to receive power from
typicalAC-DC power adapter alternatively.
Interfaces: DC Jack ( -D 6.3mm / + D 2.0mm)
Operating input voltage range for general applications:
+6.5 ~ +54VDC, 10W max. with no PoE support
Operating input voltage range for PoE applications:
+44 ~ +54VDC, 72W max. with 4 PoE full output
Note: Before you begin the installation, check the AC voltage of your area. The AC power
adapter which is used to supply the DC power for the unit should have the AC voltage
matching the commercial power voltage in your area.

-17-
2.6 Failure Relay Output
The switch provides a relay output to report failure events to a remote alarm monitoring system. The
replay output is provided with two contacts in the terminal block nextDC2 interface.
Use the provided 2P terminal plug for signal wiring and plug into the PF+/- contacts. The function is
designed as :
Alarm Events:
zInput power failure
zSpecific port link down (The specific ports can be configured by software.)
Normal: PF+ and PF- shorted
Alarm: PF+ and PF- open
Note: Be sure the voltage applied on PF+/- contacts is within the specification of
30VDC/1A max. or 120VAC/0.5A max.
2.7 Reset Button
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.

2.8 Making UTP Connections
The 10/100/1000 RJ-45 copper ports supports 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
Linkdistance: Up to 100 meters
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 con-
trol function via software management to set forced mode and specify speed and duplex mode which
match the configuration used by the connected device.

-19-
2.9 Making Fiber Connection
The SFP slots, F7 and F8 must be installed with an SFP fiber transceiver for making fiber connection.
Your switch may come with some SFP transceivers pre-installed when it is shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into SFP slot, the steps are:
1. Turn off the power to the switch.
2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP
transceiver. Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX
connector before making cable connection. The following figure illustrates a connection example
between two fiber ports:
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Network Cables
Multimode (MMF) - 50/125, 62.5/125
Singlemode(SMF)-9/125
Fiber Port Configuration
For 1000M fiber application on Port 7, 8 just leave the default port configuration Autofor fiber connec-
tion.
Note: Since the SFP slot shares the same switched port with RJ-45 connector, make sure
only one network cable type is used any time. In the case of both cable types are used
at the same time, SFP has higher priority.

-20-
2.10 Making PoE Connections
This section describes how to make a connection between a PSE port and a PoE PD device. Port 1,
Port 2, Port 3 and Port 4 are equipped with PoE PSE function. The ports are enabled to deliver
power together with network signal to a connected powered device via Cat.5 cable.
To make a PoE connection, the following check points should be noted:
1. For safety reason, the connected PoE PD (Powered Device) must be a IEEE 802.3af-compliant
device. Incompliant devices are not supported by the PoE switch model.
2. The Cat.5 cables used for the connections must be 4-pair cables. The power is sent over the
spare pairs (4,5) (7,8) of the cable. The maximum distance supported is 100 meters.
3. The DC IN power voltage supplied to the switch must be within the following range to make PoE
functionworking.
DC IN voltage range for PoE applications : +44V ~ +54V
4. The DC IN power supplied to the switch must meet the following calculation:
DC IN power = Sum of all connected PD power required + 10 watts
The PSE ports are equipped with the following capabilities:
1. Detection for an IEEE 802.3af compliant PD.
2.No power is supplied to a device which is classified non-IEEE 802.3af complaint PD.
3.No power is supplied when no connection exists on the port.
4. The power is cut off immediately from powering condition when a disconnection occurs.
5. The power is cut off immediately from powering condition when overload occurs.
6. The power is cut off immediately from powering condition when overcurrent occurs.
7. The power is cut off immediately from powering condition when short circuit condition occurs.
The figure below illustrates a connection example:
