CONFIGURATION 1 Overview The XSLAN can be configured either with DIP switches or with an html browser through Ethernet. The Html offers very useful diagnostic functions like Error rate statistics, ping, logs and so on. It is advised to use the html server when the network is complicated or when distances between switches are long. Moreover, advanced functions like Quality of Service or the asynchronous gateway can only be configured with the html server.
Configuration 1.2 Inverse-multiplexing ??Point to point Set the SW6 and SW7 OFF. ??Inverse-multiplexing The data rate will be twice what it would be with only 1 pair (2 wires). Moreover, in case of a break of 1 line, the other line will backup the transmission. Set SW6 ON and SW7 ON 2 Connecting a PC to the XSLAN for configuration If the product is coming from factory, we advise to configure the XSLAN by connecting directly the PC to one of the RJ45 ports (see paragraph 3.1). 2.
Configuration crosswired) Step 4 : Launch the navigator Enter the IP @ of the XSLAN. The Home page of the administration server is displayed Note : If the home page cannot be displayed, refer to paragraph 4 below.
Configuration 2.2 Configuration through the LAN Case of a LAN with a BOOTP or DHCP server Step 1 : Set the DIP switches SW1 OFF and SW2 OFF to select DHCP / BOOTP operation. Step 2 : Launch ETIC FINDER to detect the XSLAN over the LAN. Click the product once detected. The Home page of the administration server is displayed. Note : If the home page cannot be displayed, refer to paragraph 4 below.
Configuration Wrong Login to the administration server The access to the administration server can be protected by a login and password; If the Login & or password entered to access to the administration server have been rejected, it is possible to recover a free access, by setting SW01 ON and SW2 OFF. Careful : The factory IP address 192.168.0.128 will also automatically be assigned to the product as long as SW01 will remain ON and SW2 OFF. 4 4.
Configuration 4.2 Administration server overview System Administration To protect access to the administration server. Target To define the machines connected to the LAN ( for QoS only) Service list To define the port (TCP or others) used between the machines Date & time To set date and time of the day Syslog Export the log to a PC Firmware update Update the product fimware Save / restore To download / upload the configuration file of the product.
Configuration Email Enter the alarm email parameters IP to RS gateway (XSLAN-2220 & 2230 only) Modbus To configure the modbus gateway.
Configuration 4.3 System configuration menu 4.3.1 Administration rights menu The « administration rights » menu allows to restrict access to the administration server from the LAN, Attention : If you don’t remember this login & or password, you can restore a free access to the html server and, at the same time the factory IP address by setting SW01 ON and SW2 OFF. 4.3.2 Target list menu This menu allows to define the IP addresses of the machines belonging to the network.
Configuration “Data rate” parameter If the value “auto” is selected, the data rate will be negotiated by the LTU itself; the connection delay is much longer, because the XSLAN as to try all the data rates and select the best one. If a value from 128 Kb/s to 2.3 Mb/s is selected, the XSLAN will try to connect at that data rate. To select the right data rate, ?? refer to appendix 1 to estimate the data rate which is possible to get according to the distance. ?? Select that data rate and save.
Configuration Each port will be usually set in the “auto” mode; however, if necessary, 10 Mb/s or 100 Mb/s and full or half duplex operations can be selected. 4.5 IP Protocol & routing menu 4.5.1 IP Protocol menu Ethernet network Enter the IP address, netmask and, if there is one, the default gateway address. Routing (except XSLAN-140) It can be useful to enable the routing functions to avoid unnecessary traffic over the shdsl link when the traffic is heavy on each Ethernet network.
Configuration 4.5.2 RIP(except XSLAN-140) RIP is a protocol by which several routers exchanges their routes tables so as to facilitate the routing process of each of the routers. 4.5.3 Static routes (except XSLAN-140) A static route defines a target network (IP address + netmask) and the IP address of the router leading to that network. 4.6 Quality of service (QoS) menu (except XSLAN-140) 4.6.
Configuration 4.6.3 “Traffic classification” menu Assign each traffic (Port Nr + IP source @) to one class. Take care to assign the Premium class to only a few machines and ports. 4.6.4 Activation Activate the QoS function. If the traffic is marked outside the SHDSL domain, select the “domain extension” option.
Configuration 4.7 IP<>RS gateway menu That menu allows to configure the IP to asynchronous RS232-RS485 gateway included in the XSLAN. 4.7.1 Modbus menu The ETIC modbus gateway is made to link modbus devices connected to its serial interface to TCP modbus devices connected to the ethernet TCP/IP network. 4.7.1.
Configuration 4.7.1.3 Modbus server gateway Modbus slaves devices are connected to the serial interface. That gateway links asynchronous modbus slaves to modbus TCP clients connected to the ethernet network. Each TCP client (i.e. modbus master) can send requests to any modbus slave device of the serial interface.
Configuration the same request is received twice or more inside that delay, it will be sent only once to the slave on the serial interface. “Timeout waiting for the answer” parameter Set up the timeout the gateway has to wait for the answer of the modbus slave. “Local retry” parameter Set up the number of times the gateway will repeat a request to one of the modbus slaves on the serial interface before declaring a failure.
Configuration network (i.e. modbus slaves). To configure the modbus client gateway, ?? select the modbus menu and then “modbus client” menu; ?? enable the “modbus client” gateway and set up the parameters as follows : “ASCII / RTU protocol” parameter Select the right option “Inter-character gap” parameter Set up the maximum delay the gateway will have to wait between a received character of a modbus answer frame and the following character of the same frame.
Configuration If that slave is not a serial slave but a TCP modbus server on the ethernet network, the ETIC gateway needs to know what is its IP address. That IP address table allows to assign an IP address to each modbus slave address. ?? To assign an IP address to each modbus slave device with which the serial master device needs to communicate, click the “add a link” button; Assign an IP address in front of each modbus slave address with which the serial master device will have to communicate. 4.7.
Configuration To configure the “raw client” gateway, ?? Select the “transparent” and then the “raw client” menus. ?? Enable the raw client gateway; and set up the parameters as follows : “RS232/485 input buffer size” parameter Set up the maximum length of an asynchronous string the gateway will store before transmitting it to the IP network. “Timeout of RS232/485 end of frame” parameter Set up the delay the gateway will wait before declaring complete a string received from the asynchronous device.
Configuration 4.7.2.2 "Raw server" gateway That gateway can be used if a serial slave device has to answer requests coming from devices located on the IP network and acting like a master (also called TCP client). To configure the “raw server” gateway, ?? Select the “transparent” and then the “raw server” menus.
Configuration “TCP port number” parameter Set up the port number the gateway has to use.
Configuration 4.7.2.3 “Multicast” menu Internet Protocol multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to thousands of corporate recipients. Thus, the multicast gateway must be used when ?? a serial master device has to send requests to multiple slave devices; that devices can be IP or serial devices.
Configuration The Internet Assigned Numbers Authority (IANA) controls the assignment of IP multicast addresses. The range of addresses from 224.0.1.0 through 238.255.255.255 are called “globally scoped addresses”. They can be used to multicast data between organizations and across the Internet. The range of addresses from 239.0.0.0 through 239.255.255.255 contains limited scope addresses or administratively scoped addresses. These are defined by RFC 2365 to be constrained to a local group or organization.
Configuration 4.7.3 « Unitelway » menu The unitelway gateway is made to connect an RS232-RS485 unitelway master PLC to an IP network. ?? Select the Unitelway menu; select "enable the unitelway transceiver". ?? Enter the XWAY address assigned to the asynchronous unitelway PLC on the IP network. ?? Select « enable the IP-RS transceiver ». ?? Enter the Xway address of the master PLC and, if they exist, the Xway addresses of the slave unitelway PLCs connected to the master PLC.
Configuration 4.8 Diagnostic menu ?? Logs : The log displays the last 300 dated events : ethernet & shdsl connections and disconnections, power on, RS232 gateway events. ?? Network status : That page displays detailed information about each interface of the XSLAN (SHDSL 1 & 2, ethernet, RS232-RS485).
OPERATION 1 SHDSL link operation and troubleshooting We summarize hereafter the different steps to carry-out to bring an shdsl link into service. 1.1 Configure the products ?? Assign an IP address to each XSLAN switch See IP protocol & routing IP protocol menu Configure the SHDSL interfaces of each XSLAN switch ?? Configure the SHDSL port See “Ethernet & switching” / “SHDSL port” menu Port 1: LTU or NTU An LTU interface must be connected to an NTU interface.
Operation 1.3 Check the transmission quality level ?? Check the lower led of each SHDSL interface blinks during the connection (about 50 seconds) and is then permanently lighted. Note : the SHDSL led glitters slightly with the shds traffic. ?? Connect a PC to any of the switches to access to the html server of each of the shdsl switches. Check the data rate and quality level of each link If the quality level is 3 or more, the link is correct. if the quality level is 1 or 2, decrease the data rate.
Operation ?? Line or switch out of service the SHDSL led turns OFF, the Alarm output is open (depending on configuration); an SNMP message is sent to the SNMP server (depending on configuration). ?? When the link is set again the SHDSL led blinks and turns ON, the Alarm output is closed (depending on configuration); an SNMP message is sent to the SNMP server (depending on configuration).
