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 repla ce
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 compa ny.
2.3 Mounting the Switch on a Wall

Using DC Power Jack
When a n external power syste m is not available, the switch provides a DC jack to receive power from
typical AC-DC power adapter alternatively.
AC Power Adapters: Optional commerci al rated a da pters are availa ble for purcha sing.
Non-PoE applications Rated output DC7.5V 0.5A / 1A / 1.2A
PoE applications Rated input 100V ~ 240VAC, Output 48VDC / 24W (About 20-21W is
reserved for PoE PDs connected.)
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.
* For PoE applications, make sure the rated output power meets the required voltage
and power consumption required by all connected PD devices. Refer to sec. 3.3 for
more information.

3. Making Connections
3.1 Making UTP Connections
The 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 / 4-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
Link distance: 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.
3.2 Making Fiber Connection
The SFP slot must be installed with an SFP fiber transce iver f or making fiber connection. Your
switch may come with an SFP transceiver pre-installed when it is shipped.
To install an SFP fiber transceiver into the 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
tra nsce iver. Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
4. Turn on the power to the switch.
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
Single mode (SMF) - 9/125

3.3 Making PoE Connections
This section describes how to make a connection between a PSE port and a PoE PD device. For the
PoE switch model, Port 2, Port 3, Port 4 and Port 5 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.
T o 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
function working.
DC IN voltage range for PoE applications : +43V ~ +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 + 3 watts
The PSE ports are equipped with the following ca pa bilities:
1. Detection for an IEEE 802.3af compliant PD.
2. No power is supplied to a device which is cla ssified non-IEEE 802.3af complaint PD.
3. No power is supplied when no connection exists on the port.
4. The power is cut off i mmedi ately from powering condition when a disconnection occurs.
5. The power is cut off i mmedi ately from powering condition when overload occurs.
6. The power is cut off i mmediately from powering condition when overcurrent occurs.
7. The power is cut off i mmedi ately from powering condition when short circuit condition occurs.
