Troubleshooting the LAN Connection
Troubleshooting the Initial Connection
Procedure
This procedure verifies the performance of the LAN interface. To check
logic analyzer performance, refer to the logic analyzer’s Service Guide.
1Go to the System External I/O menu.
2Verify that the LAN Settings box and the X-Window box are
available.
If these boxes appear, go to the next step. If the boxes are not there,
then the LAN interface is not properly installed. If the screen is
completely blank, then there might be loose cables.
3Go to the System Test menu.
4Select Load Test System.
If you do not have a copy of the performance verification files on the
hard disk, you need to insert the disk containing the performance
verification files into the flexible disk drive.
5Select Analy PV, and then select Sys PV from the pop up.
6Select External I/O, and then select System Test from the pop up.
7Select LAN Test, then select Run.
8Verify that the tests pass.
If all of the tests pass, then go to the next step. If any of the tests fail,
then the LAN hardware is suspect.
The status number in the LAN Test field indicates whether the LAN
hardware or software caused the failure.
•To troubleshoot the failure using the status number, note the number, then
compare it with the status number descriptions and perform the
recommended action. Refer to "Status Number" on the next few pages for
status number descriptions and recommended actions.
•To verify the LAN hardware, check that the LAN cable is good and that all
signal lines in the cable have electrical integrity.
