Problems with external networks

If you have a problem with an integrated server's external network

• Review the integrated Windows server event log for either communication errors or device driver errors. You can use the Windows Event Viewer to do this. Event logs associated with external adapters supported by 2890, 2892, and 4812 Integrated xSeries® Servers may have one of the following in the event log Source field: IBMTRP, PCNET, ALTND5, E100B, or E1000. If you can not find text in event logs for the IBMTRP token-ring service, you need to make changes in the Windows Registry.

  Note:

  If you are not familiar with the process for making changes in the Windows Registry, contact a service representative.

  If you are familiar with this process, to make the text in the event logs viewable, complete the following steps.
  1. From the Windows Start menu, click Run.
  2. Type regedit.
  3. In the Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\System\IBMTRP
  4. Select EventMessageFile.
  5. From the Registry Editor Edit menu, select Modify.
  6. Type %SystemRoot%\System32\netevent.dll;%SystemRoot%\System32\ibmsgnet.dll
  7. Close the Registry Editor and restart the integrated server.
• For Ethernet adapters, ensure that a driver with iSeries or AMD PCNET Family Ethernet Adapter (PCI) in its name is listed and has a status of started.
  1. Click on Start, then Administrative Tools, then Computer Management, then System Tools, then Device Manager, then Network Adapters.
  2. Ensure that a driver with iSeries or AMD PCNET Family Ethernet Adapter (PCI) in its name is listed and has a status of started.
• For token-ring networks, also in Device Manager, ensure that you have started the IBM High-Speed 100/16/4 Token-Ring PCI Adapter or IBM PCI Token-Ring Adapter.

  Note:

  The start up setting should be Enable.

• For token-ring networks, ensure that the Network Data Rate setting is appropriate for your network.
• For Ethernet networks, ensure that the Link Speed and Duplex settings are appropriate for your switch or hub. If your 4812 or 5701 does not connect at speeds greater than 100 million bits per second, check your switch's specifications for compliance with the IEEE 802.3ab standard. Windows LAN drivers for 4812 or 5701 Gigabit Ethernet ports may be limited to 100 million bits per second when connected to some early model non-compliant switches.
• The 10/100 Mbps Ethernet port on the 2892 Integrated xSeries Server does not support direct connection to certain 10 Mbps hubs and routers that lack auto-polarity functionality. If you are having difficulty getting your 2892 10/100 port to work at all with a 10 Mbps hub or router, check its specifications for auto-polarity support. Also, see if your 2892 10/100 port works with other devices.
• If the problem still persists, check the technical information databases at the IBM iSeries Support Web page . If you cannot find the solution there, contact your technical support provider.
