1. Introduction The 8-port compact Fast Ethernet switch is equipped with 2.0 Gbps Packet Switch engine as particular packet forwarding and filtering mechanism to fulfill industrial communications on the filed site. It provides the graceful packet forwarding ability to handle 64~1552 packet size into 2 priority queues which complies with quality of service for the best data forwarding performance.
1-2. Packing List The Industrial 8-port Fast Ethernet Switch is packaged with the following items: ◎ Product ◎ CD : User Manual Contact your sales representative if any item is missing or damaged.
2. Hardware Description This session will introduce the hardware information as following: 2-1. Dimensions 2-2. Front Panel 2-3. Bottom View 2-4. LEDs of system and port 2-5. Connectors 2-1. Dimensions The dimension of 8-port Industrial Fast Ethernet Rail Switch is 120 mm (H) x 55 mm (W) x 108 mm (D). The following is the drawing of detail mechanical design: 2-2. Front Panel The Front Panel of the Industrial 8-port Fast Ethernet Switch is shown in Figure A.
2-3. Bottom View The bottom view of the Industrial 8-port Ethernet Switch consists of one 6-pin removable terminal block connector for two DC power inputs and event alarm output. There is one 9-pin DIP SWITCH on the bottom for alarm control of port or power event selection.
2-4. LED Indicators There are some system diagnostic LEDs and Ethernet Port LEDs located on the front panel of Industrial 8-port Ethernet Switch. These LED indicators provide administrators with real-time system status. Table-1 gives the descriptions of the function of each LED indicator. LED PWR1 Status Green on Description Power is on. PWR2 Off Green on No power is being supplied. Power is on. Alm Off Red on No power is being supplied. Port link down or power failure event occurred.
2-5. Ports RJ-45 ports (Auto MDI/MDIX): 8 x 10/100 Mbps ports (auto-sensing RJ-45) for 10Base-T /100Base-TX device connection. The RJ-45 ports will auto-detect 10Base-T and 100Base-TX connections. Auto MDI/MDIX function allows users to connect another switch or workstation without the straight through cable or the crossover cable. See Figure C and C-1 for the schematic diagram of straight through cable and crossover cable. All of the RJ-45 ports of the switch support auto-MDI/MDI-X function.
3. Mounting Installation DIN-Rail Mounting The DIN-Rail clip is already attached on the rear side of the switch supports EN 50022 standard DIN Rail, in the following diagram includes the dimension of EN 55022 DIN Rail. Follow the steps below to mount the switch on the DIN-Rail track. 1. Insert the upper end of the DIN-Rail clip into the back of the DIN-Rail track from its upper side 2. Lightly push the bottom of the DIN-Rail clip into the track. 3.
4. Hardware Installation The following figure illustrates a typical application of the switch in field site. It includes Enterprise communication backbone network, Factory communication, field site communication and field site control layers. The control equipments access and report production information through the switch and uplink to factory communication level by fiber or copper which with network redundancy. This session will introduce the hardware installation, includes: 4-1.
4-1. Wiring the DC Power Inputs Follow the steps below to wire the switch dual DC power inputs. Before install power, be sure the power supply module is compliance with UL certificated and the power system is shut down to avoid any damage. About the wiring please refer following diagram.
4-2. Wiring the Alarm Relay The switch provides one dry relay output for power or port link event. The alarm relay default is “open” and form a close circuit when the even is occurred. The relay conductor ability is 24W. When it connects with a DC 24V power source, the maximum current is 1A. The following diagram shows how to create an alarm circuit. 4-3. Wiring Earth Grounding In the real fields, there are a lot of automatic devices, such as AC motors, electric welding machine and power generator.
4-4. Enabled the Event Alarm Function This session will introduce how to configure and enable the event alarm to alert maintenance engineer once the system event is occurred. The switch is equipped with one dry relay output for port link fails or power fails. The feature is controlled by digital control circuits. It effects immediately without system reset when DIP SWITCH is changed. On the bottom side of the switch, there is one 9-Pin DIP SWITCH for alarm control.
4-5. Cabling The UTP cable connection between the switch and the attached devices (switches, hubs, workstations, etc.) must be less than 100 meters (328 ft.) in length. 4-6. System Power-On and Testing 1. Take the Industrial 8-port Fast Ethernet Switch out of the box. 2. To place the switch on the DIN-Rail track, please refer to the Mounting Installation section. 3. Pull the terminal block off the switch and wire the power lines.
10. To enable the “Command Line mode”. Click on Run in the Start Menu Æ type Command Æ click OK to continue. Type ping 192.168.1.1 command to check the connection. Here uses 192.168.1.1 (IP address) as an example.
11. Repeat step 10 to make sure that the connection of each device connected to the switch is successfully established. 12. Power on the PC host. Activate the Command Line mode and ping the connected Ethernet device by typing “ping 192.168.1.1 –t” command to see if it will respond. Do remember the PC host IP address is same subnet address as the target device – 192.168.1.1. 13. The parameter-”t” allows you to continue to ping the network device. Shown in the figure below.
5. Packet forwarding ability The switch features packet filtering functions for broadcast packet control protection and QoS. Both of features can provide more graceful performance in a crowded network by traffic filtering and prioritize. This session will introduce the principle of traffic control and forwarding precedence, including “Broadcast control” and “Quality of Service”. 5-1.
IEEE 802.1Q Type of Service for IPv4 /IPv6 packet The switch also provides the IP layer CoS (Class of Service) function by recognizing the priority octet and mapping it to the corresponding priority. For an IPv4 packet, it is embedded in the TOS (type of Service) Octet. For an IPv6 data packet, the Traffic Class Octet is used to differentiate the Class of Service.
6. Trouble shooting ◎ Make sure you are using the correct DC power suppliers (DC12 to 48 V). Do not use power suppliers with DC output over 48V. It may damage devices. ◎ Select Ethernet cables with specifications suitable for your applications to set up your systems. Ethernet cables are categorized into unshielded twisted-pair (UTP) and shielded twisted-pair (STP) cables. Category 3, 4, 5, 6 Ethernet cables are suitable for systems with 10 Mbps transmission speed.
