INSTALLATION 1.3 DIP switches and pus-button DIP switches SW 1 SW 2 OFF OFF The current IP@ of the product is the stored IP @ ON OFF The active IP@ of the product is the factory IP@ : 192.168.0.128 No login and password are required to access to the html server OFF ON The active IP@ is provided by the BOOTP or DHCP server.
INSTALLATION Ventilation 2 To avoid overheating when the ambient temperature is high, leave a 1 cm (0.5 inch) space on each side of the product. Supply voltage 3 The product comes with 2 separate voltage inputs, so that 2 external power supply modules can be connected to the product. If one power supply module fails, the XSRING will be powered by the other. The supply voltage must be • • strictly lower than 60 VDC and higher than 9 VDC for XSRING2400 and XSRING-2230.
INSTALLATION 6 RS232 (XSRING-2220 and XSRING-2230) The RS232 data rate can be tuned from 1200 to 115200 b/s with parity (even / odd) or no parity. The data terminal must be less than 10 meters far from the modem.
INSTALLATION 8 SHDSL line SHDSL cable The XSRING is delivered with 2 cables (CAB614); each cable allows to connect the product to one line. The cable comes with 2 wires which have to be connected to the two wires of the twisted pair. The 2 wires can be inverted. Case of a ring or of a multidrop connection It is more simple to connect the SHDSL port 1 of one switch to the SHDSL port 2 of the other switch according to the drawing hereafter.
INSTALLATION Surge voltage arrester if the line is exposed to the lightning, we advise to use an over voltage arrester at each end of the line. We have selected the Phoenix Contact module TT-2-PE-24D; it must be wired as indicated opposite. Line cable shield : If the line is shielded, the shield must be connected to the earth; only at one end if it is not interrupted along the line.
INSTALLATION 9 Input and output Input That input is not isolated. if it is opened, an SNMP trap will be sent to the SNMP server is that function has been enabled. Alarm output 1 relay output is provided to indicate an alarm. The alarm condition can be selected using the html server. The Output is open when the XSLAN is OFF or when a SHDSL line is not connected.
DIP-SWITCHES SET UP 1 Overview The XSRING can be configured either with DIP switches or with an html browser through Ethernet. The Html server offers useful diagnostic functions like Error rate statistics and logs. It is advised to use the html server when the network is complicated or when distances between SHDSL switches are long. Moreover, advanced functions like Quality of Service, serial gateway and VLAN can only be configured with the html server. 2 Dip switches configuration 2.
DIP SWITCHES SET UP Remark : It is advised to select the AUTO mode only for test purposes, because the connection delay can be long. 2.3 SHDSL network topology DIP switches (SW6, SW7) • Point to point or daisy chain Set the SW6 and SW7 OFF. • Failsafe ring The ring topology provides a much better availability, in particular when the network includes a great number of SHDSL switches : if one line fails, the communication remains possible as previously between all the devices.
DIP-SWITCHES SET UP 2.4 SHDSL port 2 configuration Once the SHDSL port 1 has been set up with the DIP switches SW3, SW4, SW5 and once the network topology has been configured with the DIP switches SW6 and SW7, the SHDSL port 2 configuration is automatically set up by the product itself. 3 Testing the SHDSL connection and adjusting the data rate • Connect two SHDSL switches to the line and power them up as explained at the “Installation” chapter.
DIP SWITCHES SET UP • Connect a PC to the ring master XSRING and ping periodically a remote device. • Disconnect the ring master XSRING from its line 1 and check the Pings go on receiving a response after the cicatrisation delay. • Check the failsafe ring led turns red. • Check the digital alarm output opens. • Connect the XSRING to its line 1. • Check the output is closed and the failsafe ring led turns green. • Do the same with the line Nr 2 of the ring master XSRING.
HTML SET UP Setting-up the XSRING with the Html server is mandatory when the distance between two SHDSL switches is close to the limit to take advantage of the Diagnostic functions, or when advanced functions like VLAN, Quality of Service, SNMP, serial gateways, which can only be configured with the html server, are required.
HTML SET UP & DIAGNOSTIC 2 Enabling html configuration Coming from factory, the DIP switches SW1 and SW2 are set OFF (ready for html configuration); and the IP address of the XSRING is 192.168.0.128. Check the DIP switches SW1 and SW2 are OFF. Remark : When the DIP switches SW1 and SW2 are OFF, the active IP address is the stored IP address. 3 Connecting a PC to the XSRING for configuration 3.
HTML SET UP & DIAGNOSTIC Copy and paste : Parameters must be entered with the keyboard; they cannot be pasted. However, it can be useful to paste a string when it is long to avoid errors. In that case, paste the string, delete the last character of the pasted string, and enter it again with the keyboard. Saving and restoring the parameters file (see the maintenance chapter) A parameters file can only be downloaded to a product with the same firmware version.
HTML SET UP & DIAGNOSTIC 3.3 Modifying the configuration from the LAN Step 1 : Ensure the DIP switch SW1 and SW2 are OFF to select the stored IP @. Step 2 : Launch the html browser and enter the IP address assigned to the router. Or, launch the ETICFINDER utility to detect the XSRING IP address. Remark : If the home page cannot be displayed, refer below.
HTML SET UP & DIAGNOSTIC Remark : The SW01 and SW02 must not be left in that position during operations. 6 Recovering the factory configuration For any reason, it may be necessary to restore the factory configuration of the SHDSL switch. To restore the factory configuration, • • • Switch OFF the power supply. Press the push button on the top part of the IPL-E router and switch ON the power supply. Keep the push button pressed until the Operation led turns red.
HTML SET UP & DIAGNOSTIC 9 Assigning an IP address to the LAN interface An IP address must be assigned to that interface. The HTML server is located at that IP address. To assign an IP address to the LAN interface, • • 10 select the “IP protocol and IP routing” menu and then the IP menu; enter the IP address, the netmask and the default gateway address.
HTML SET UP & DIAGNOSTIC 3. Routes must be created or the RIP protocol must be enabled. A route is a table which registers which gateway address must be used to transfer IP packets to a particular network.
HTML SET UP & DIAGNOSTIC To register a route, • select the “IP protocol & routing” menu and then the “routing” menu, • click the ”Add a route” button. • Enter the parameters of the route. To enable the RIP protocol instead of programming routes, • select the “IP protocol” and then the “RIP” menu. • Select the “Activate” checkbox.
HTML SET UP & DIAGNOSTIC 11 Multidrop network set up 11.1 Set up Once the XSRINGs will have been set up, they must be connected to the line according to the drawing opposite. To set up the SHDSL ports, • Select the Ethernet & switching” menu and then the “SHDSL port” menu. Setting up port 1 • Select the LTU checkbox. • Select the data rate according to the table of the appendix 1. Note : If the “auto” option is selected, it will cause the XSRING to try all the data rates.
HTML SET UP & DIAGNOSTIC 11.2 Testing the SHDSL connection and adjusting the data rate • Connect two XSRINGs to a line, check the line led (the lower led of each SHDSL connector) blinks during the connection (about 45 seconds) and then lights on. • If the led blinks endlessly, it means the connection cannot be established; select a lower data rate. • Once the connection is established, select the “Diagnostic” menu, and then the “Network status” menu and then the “Statistics” menu.
HTML SET UP & DIAGNOSTIC 12 4,6 Mb/s point to point connection set-up 12.1 Overview A point to point communication at a data rate of up to 4,6 Mb/s instead of 2,3 Mb/s can be provided with two twisted pairs. An SHDSL connection is established at a data rate of up to 2,3 mob/s on each twisted pair. The data flow is automatically shared over the two pairs. 12.2 SHDSL ports set-up Once the XSRINGs will have been set up, they must be connected to the line according to the drawing opposite.

HTML SET UP & DIAGNOSTIC The spanning tree algorithm (STP) : STP is the usual name of the algorithm described by the IEEE 802.1D norm; it works with switches from different manufacturers if they manage Spanning Tree or Rapid Spanning Tree even if some segments of the network are optical, or 10/100BT or SHDSL segments. The spanning tree algorithm if efficient when the topology is complex, like a double attachment rings for instance. 13.
HTML SET UP & DIAGNOSTIC Setting up port 2 • Select the NTU checkbox. • Select the “Signal power” value “Auto”. 13.3 Setting up a failsafe ring using the ETIC ring To set up the RING master switch • Select the “Ethernet & switching” menu and then the “failsafe ring” menu. • Select the “failsafe ring active” checkbox. • Select the “Ring master” checkbox. • Click the red button “REBOOT” to restart the product.
HTML SET UP & DIAGNOSTIC • Once the connection is established, select the “Diagnostic” menu, and then the “Network status” menu and then the “Statistics” menu. Check the “SNR margin” is greater than 6. Otherwise decrease the data rate. • Select the “Diagnostic” menu, and then the “Logs” menu. Check the XSRING remains permanently connected. Disconnections must be very rare. If disconnections are frequent, check the line itself and / or decrease the data rate. 13.
HTML SET UP & DIAGNOSTIC 14 VLAN set up 14.1 Overview VLAN is a flexible group of devices that can be located anywhere in a network, but that can communicate as if they are on the same physical segment. Devices within a VLAN can only communicate directly with devices belonging to the same VLAN. If a device belonging to VLAN 1 needs to communicate with devices in VLAN 2, the traffic needs to pass through a routing device or Layer 3 switch.
HTML SET UP & DIAGNOSTIC Before being transmitted to the port the Ethernet frames are untagged by the XSRING. ”Trunk” port An Ethernet port must be set up as a “Trunk” port, when that port is used to connect an SHDSL network to another network like an optical network for instance. All tagged Ethernet frames entering the port are transmitted towards the SHDSL network or other ports. Untagged Ethernet frames are tagged by the XSRING with the right VLAN ID code.
HTML SET UP & DIAGNOSTIC “Tag” port An Ethernet port must be set up as a “Tag” port, when the device connected to that port tags the Ethernet frames by itself. Ethernet frames entering the port are transmitted towards the SHDSL network or other ports only if they are tagged with one of the four VLAN ID codes registered by the XSRING.
HTML SET UP & DIAGNOSTIC 15 Quality of service (QoS) set up 15.1 DiffServ benefits & overview The goal of Quality of Service algorithms is to guarantee that critical data flows will be transmitted with lower delay than others. For instance, it can be difficult to transmit on the same SHDSL network an important video data flow and a small but critical PLC protocol data flow. To solve that question, the XSRING implements the DiffServ algorithm.
HTML SET UP & DIAGNOSTIC • Assigning each traffic to the classes Each traffic (Service plus target) entering the shdsl network can be assigned to one class; Any traffic not assigned to one class is supposed to belong to the default class. • How it works ? The IP data flow entering the XSRING switch is analysed and marked as premium or gold or silver or bronze or default and then transported through the shdsl network with the relevant priority. 15.
HTML SET UP & DIAGNOSTIC Step 5 : Classify the traffics • Select the QoS menu and then the “Traffic classification” menu. • Click the “Add a traffic” button. The traffic window is displayed. • Select a service (modbus TCP or html or FTP …), a target and a class and click OK.
HTML SET UP & DIAGNOSTIC 16 SNMP set up The XSRING is compliant with the MIB2. The SNMP manager can acquire the status (Connected or not connected) of each SHDSL port. The XSRING is also able to send SNMP traps when each SHDSL connection is established. or when each SHDSL connection is disconnected. To enable the SNMP traps function, • Select the “Alarm” menu and then the “SNMP” menu : • Select the “Activation” checkbox. • Enter the IP address of the management system.
HTML SET UP & DIAGNOSTIC 17 Serial gateway set up The XSRING-2220 features 1 RS232 and 1 RS485 – 2 wires – ports. The XSRING-2230 features two RS232 serial ports. A serial gateway can be assigned to each serial port . However, if the same type of gateway is assigned to both serial ports, the UDP or TCP port numbers must be different. For instance, it is not possible to use modbus TCP with the port 502 at the same time on the serial ports 1 and 2.
HTML SET UP & DIAGNOSTIC 17.1 « Modbus » gateway 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. A TCP Modbus client device is a device connected to the Ethernet TCP/IP network and able to send a modbus request to a modbus TCP server which is in charge of answering; A TCP modbus client is equivalent to a master.
HTML SET UP & DIAGNOSTIC To configure the Modbus server gateway, • select the modbus menu and then modbus server, • enable the modbus server gateway and set the parameters as follows: “Modbus protocol” parameter : Select the RTU or ASCII option “Activate Proxi cache” parameter : Enable the proxi option if you wish to avoid to frequent requests on the serial interface.
HTML SET UP & DIAGNOSTIC “Inter-character gap” parameter : Set up the maximum delay the gateway will have to wait between a received character of a modbus answer frame on the serial interface and the following character of the same frame. “Modbus slave address* parameter : If only one modbus slave device is connected to the serial interface, set the modbus address of the device; any TCP modbus request received by the gateway will be sent on the serial interface using that modbus address.
HTML SET UP & DIAGNOSTIC 17.1.2 “Modbus client” gateway That gateway can be used only if a serial modbus master device is connected to the serial interface of the XSRING. That modbus master can send requests to slaves connected to the serial interface or to up to 256 modbus TCP servers connected to the IP network (i.e. modbus slaves).
HTML SET UP & DIAGNOSTIC “TCP inactivity Timeout” parameter : Set the time the gateway will wait before disconnecting the TCP link if no characters are detected. “TCP port number” parameter : Set the TCP port number the gateway has to use. “IP address table” : When the serial master sends a modbus request to a slave, it includes the modbus address of that slave. 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.
HTML SET UP & DIAGNOSTIC 17.2 RAW TCP gateway 17.2.1 Raw client gateway The RAW client gateway can be used if a serial “master” device has to send requests to one slave device (also called server) located on the IP network. The server can be either an ETIC gateway or a PC including a software TCP server. • Select the “transparent” and then the “raw client COM1” or the “raw client COM2” menu .
HTML SET UP & DIAGNOSTIC “TCP port number” parameter : Set the port number the gateway has to use. If the Raw TCP client gateway is assigned to both serial COM ports, the TCP port numbers must be different on each port. “Raw server IP address” parameter : The raw client gateway is able to communicate with a raw server gateway. Assign an IP address to define the destination gateway. 17.2.
HTML SET UP & DIAGNOSTIC Once declared complete, the gateway will transmit the string to the IP network. “TCP inactivity Timeout” parameter : Set up the time the gateway will wait before disconnecting the TCP link if no characters are detected. “TCP port number” parameters : Set up the port number the gateway has to use. If the Raw TCP server gateway is assigned to both serial COM ports, the TCP port numbers must be different on each port.
HTML SET UP & DIAGNOSTIC 17.3 RAW UDP gateway 17.3.1 Overview The RAW UDP gateway enables you to connect together a group of serial or IP devices through an IP network. The group can include IP devices if they have the software pieces able to receive or transmit serial data inside UDP. Serial data transmitted by each device is transmitted to all other serial devices through the IP network. A table of IP destination gateways is stored in each IPL-E belonging to the group.
HTML SET UP & DIAGNOSTIC • Select the “Activate” option. « Serial input buffer size” parameter (value 1 to 1024) : Sets the maximum size of an UDP frame. “End of frame time-out” parameter (value 10 ms to 5 sec ) : Sets the delay the gateway will wait before sending the UDP frame towards the IP network when no characters are received from the serial interface. «UDP port number» parameter : Sets the UDP port number.
HTML SET UP & DIAGNOSTIC 17.4 “Multicast” gateway 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.
HTML SET UP & DIAGNOSTIC 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.
HTML SET UP & DIAGNOSTIC 17.5 « Unitelway » gateway 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.
HTML SET UP & DIAGNOSTIC 18 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 XSRING (SHDSL 1 & 2, ethernet, RS232-RS485).
