1. Introduction The switches are 5-port Fast Ethernet switches which are featured with four copper ports and one combo port. The combo port comes with one RJ-45 and one SFP slot. The SFP slot can be mounted with a fiber transceiver optionally to support a fiber connection. For more coming PoE (Power Over Ethernet) applications, the PoE switch model is equipped with PoE design in four copper ports. With proper 48VDC power supply, it is able to deliver power to four PoE PD devices via Cat.5 cables.
1.1 Features Provides 5 10/100Mbps RJ-45 and one 100Mbps SFP slot All copper ports support auto-negotiation and auto-MDI/MDI-X detection Provides full wire speed forwarding Supports IEEE 802.3x flow control for full-duplex and backpressure for half-duplex Provides SFP slot for optional optical fiber connection Provides four IEEE 802.

2. Installation 2.1 Unpacking The product package contains: • The switch unit • 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.
2.4 Din-Rail Mounting The steps to mount the switch on a Din-rail are: One Din-rail mounting bracket is provided in the product package as shown below: Install the bracket on the bottom of the switch unit. Mount the device on a Din-rail.
2.5 Panel Mounting One panel mounting bracket is provided in the product package as shown below: Install the bracket on the bottom of the switch unit. The final dimension after panel bracket is installed is shown below: 2.6 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 system.
Using Terminal Blocks Three terminal contacts are provided: Vdc Positive (+) terminal Vdc Negative (-) terminal Chassis ground * Working Vdc for general application: +6V ~ +60VDC * Working Vdc for PoE application : +43V ~ +54VDC (Typ. 48V) One 3P terminal plugs are provided together with the switch. 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 the terminal block socket.
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.
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. 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.
3.4 LED Indication LED Function State Interpretation POWER Power status ON OFF The power is supplied to the switch. The power is not supplied to the switch. LINK/ACT Port link status ON A port link is established. (No traffic) BLINK Port link is up and there is traffic. OFF Port link is down. 100M/10M Port speed status ON OFF Speed 100M is selected. Speed 10M is selected. PoE STATUS Port PoE power ON OFF PoE power is delivered on the port. PoE power is shut down.
