Chapter 1 Characterizing the problem
30 Profile XP Service Manual 23 July 2004
What has changed?
If the media platform has been working, but has suddenly developed a problem, think
of what has changed in the system.
• Have you changed resources for any of the channels?
• Have you installed any software?
• Have you installed or removed a board?
If reversing the changes restores the system, perhaps there is a problem with the
software or hardware that was installed or removed.
What error indications were reported by the NetCentral system?
The NetCentral system monitors the operational status of the media platform, keeping
track of a number of operating parameters and the health of the circuit boards. Many
of the messages displayed by the NetCentral system contain the remedy for a problem
along with the notification. NetCentral also generates log files that you can use to help
determine where and when faults have occurred. Refer to “Viewing logs” on
page 134.
What attempts have you made to remedy the problem?
Keep track of efforts you make to remedy your problem. In the event that you need to
contact Grass Valley Support, this information can greatly assist the person working
with you to isolate and correct the problem.
Readily diagnosed problems
Many problems are easily diagnosed because they are primarily hardware faults that
are indicated by messages at boot time or because they generate a NetCentral Alarm
or an Attention message.
• Power-supply failure
• Fan failure
• Temperature (fans/filter/overload)
• Applications processor boot failure
Any of the plug-in circuit boards in the media platform will generate a NetCentral
Alarm message if the board fails. This message states the name of the board and its
slot location in the Profile XP media platform, and recommends that you replace the
board.
