Troubleshooting video network
problems
If your video network problem is a result of equipment failure, your first indication
might be a message in the NetCentral system. Look through the table in “Checking
NetCentral messages” for the Warning or Alarm message you might see, and the
suggested corrective action.
When you are troubleshooting video network problems and you have determined that
the problem is hardware related, remember that you are trying isolate the fault to a
field-replaceable unit. Most video network problems will be confined to:
• the Fibre Channel Video Network board
• the Ethernet Video Network board
In general, you can verify or rule out hardware problems by using the Profile XP
diagnostics described in Appendix A, Diagnostic Tools. If the diagnostics indicate
that a board is defective, replace that board.
In many cases an improper configuration setting or other change in the system setup
can result in video network problems. Search through the symptoms in “Correcting
common Fibre Channel video network problems” or “Correcting common Ethernet
video network problems” then try the corrective action.
Checking NetCentral messages
These are Warning and Alarm messages you might see from the NetCentral system
that relate to the video network. No entry in the Possible Cause column means that the
cause is implicit in the problem statement or that knowing the cause is unimportant to
the solution or that, in the case of status messages, there is no cause.
