Troubleshooting miscellaneous system
problems
This chapter covers problems and NetCentral messages from a variety of subsystems
in the Profile XP media platform including:
• Problems related to the Applications Subsystem I/O, including tables for Ethernet
problems and common problems associated with using Configuration Manager
• NetCentral messages for the Real Time Processor, including RefGen and GPI
• NetCentral messages for power supply and thermal subsystem problems
Search the tables for the problem you are experiencing, then try the corrective action.
Some problems have more than one corrective action.
Applications subsystem problems
No entry in the Possible Causes column means that the cause is implicit in the
problem statement, that knowing the cause is unimportant to the solution, or in the
case of status messages, there is no cause.
