Comtrol VS3000S - Manual (Page 28)

28 Problem Resolution Checklist
Troubleshooting
• If you are operating in a multiple-server environment and a backup
server has taken over control of the VS3000, check (if possible) to
make sure the backup server has the same Port, SPID, Directory
Number, and MAC configuration as the primary server.
• If this is a Windows NT installation, use the ISDN Monitor program
to trace and log the messages being passed between the NT server
and the VS3000. Use the ISDN Cause Codes section of this manual
to interpret the results. Also note that other error messages may be
displayed in the Event Log.
• If this is a Novell installation, use the vs3kcfg.nlm utility to trace
and log the messages between passed between the server and the
VS3000. Use the ISDN Cause Codes section of this manual to
interpret the results. Also note that other error messages may be
displayed in the Console Log.
• If you have more than one VS3000, follow the Replacing Units in
Service procedure for your operating system to “hot-swap” VS3000
units. If this corrects the problem, the VS3000 you have removed
from service may be defective or need repair.
• When all else fails, remove and reinstall the VS-Link software.
