Page 13: Subnet Communication Upon Network Failure
Even though the Metasys Ethernet Router looks like a data router to the Metasys Network, most communications experts would call it a network gateway. To the Ethernet network, the router looks like a normal IBM PC workstation. Unlike typical network gateways and routers, the Metasys Ethernet Router does not process: •... -

Communication Processor. For example, an EXP-CXS 4-port coaxial star expansion module could be used to connect to the Metasys N1 ARCNET subnet. Once an appropriate expansion module and the Communication Processor are installed, the unit is ready for configuration. - Page 20 The left side of the screen displays information to be loaded into the SOCKET.CFG file.

Appendix A, add to this file the ARCNET Subnet Address (Column 1) and IP Address (Column 2) of each Metasys Ethernet Router that will be connected. Specify these two addresses on the same line and above the “000” terminating flag at the end of the file. The # symbol means that the text following the # is a remark. - Page 22 COM2, the DOS prompt should be visible. You can clear the screen by typing in CLS and then return. 4. Verify that the router is communicating with Metasys by using TESTNET. TESTNET reads the configuration file (ROUTER.CFG) and attempts to “ping” each router that is listed.

Page 23: Reconfiguring The System
401 that is added to a Metasys Ethernet Router system must be Revision K or later. All NCM200s and NCM300s are compatible with the Metasys Ethernet Router. To add a new NCM or PC to an existing subnet: 1. Determine the correct subnet and node address for the new NCM or PC. -
Page 24: Moving An Existing Ncm Or Pc To A Different Subnet
5. Physically attach the new NCM or PC to the ARCNET segment that you have selected. 6. You do not need to make any changes to the Metasys Ethernet Router or the ROUTER.CFG file. The router automatically routes messages correctly using the subnet address for the new device. -

Metasys database. This is done by updating the DDL global file. 5. Physically attach the device to its new ARCNET segment. 6. You do not need to make any changes to the Metasys Ethernet Router or the ROUTER.CFG file. The router automatically routes messages correctly based on the new subnet address for the device. - Page 26 The response to the XPING command should indicate that the new router is communicating. 6. Modify the ROUTER.CFG file that is located in each Metasys Ethernet Router using the configuration program. Add a new line to the file that lists the subnet address and the IP address for the new router.

Use the Metasys Ethernet Router Planning Form B to update the TCP/IP configuration on each of the existing Metasys Ethernet Routers. The procedure for updating the TCP/IP information is described in a previous section, Changing the Ethernet Network.

Page 29: Chapter 4 Troubleshooting
Troubleshooting Because the Metasys Ethernet Router hardware consists of an embedded DOS computer, knowledge of DOS will help in troubleshooting the system. Booting Up the Router When first activated, the Metasys Ethernet Router computer runs through a self test. If an error is detected, the router will stop operating then repeatedly display an error message advising the operator to press “Q”... -
Page 30: 4: Statistics Screen Available At Com1
Figure 4 Statistics Screen available at COM1 • If an Invalid message counter is non-zero, it indicates that an Invalid Metasys message was detected. The last Metasys message that was invalid is displayed. • A non-zero Failure counter indicates an Ethernet problem, and results in the display of an error number. -
Page 31: Xping Command
Note: Once “Q” is hit, the router software stops transmitting Metasys messages, and its subnet loses communications with the rest of the Metasys Network. To restart the router from the DOS prompt, type REBOOT. XPING Command The XPING command verifies that messages can be sent and received over the Ethernet network by transmitting continuous pings. -
Page 32: Ipstat Command
1. Configure the Metasys Ethernet Router’s IP address, existing LAN Router IP address, and subnet mask using information from the customer’s network manager. 2. The Metasys ARCNET subnet addresses need to match the router configuration file. Each ARCNET segment needs a TD990200-0ME... -
Page 33: Debugging Arcnet Failures
The Metasys DDL files must use the correct subnet addresses. 3. All of the Metasys devices on one ARCNET segment need to have the same subnet address. Although ARCNET hubs and links result in multiple ARCNET segments, for the purposes of the Metasys Ethernet Router, it is all considered one subnet. -
Page 34: Metasys Devices Do Not Respond
Metasys Devices Do Not Respond If any other node on the same ARCNET segment responds normally, the router is not at fault. The problem could be caused by a Metasys device failure or an ARCNET cable problem. Check the device for... -
