Troubleshooting
C-1 Introduction
This appendix outlines errors that may occur during system
operation and likely remedies for these problems.
C-2 Troubleshooting with Error Messages
This section describes error messages and their use in
troubleshooting. Since many errors can be caused by poor
cable connections, you should verify that all cables have been
connected firmly to their proper receptacles. If error messages
persist after the recommended adjustments have been made,
contact MultiTech Systems for maintenance.
Post Beep: The BIOS generates two beeping (audible) error
codes.
1 A single long beep followed by three short beeps indicates
that a video error has occurred and the BIOS cannot initialize
the video screen to display any additional information.
2 A single long beep sounded repeatedly indicates that a
DRAM error has occurred.
CMOS Battery Failure: If the CMOS battery is low or dead, it
should be replaced. The battery is located inside the real-time
clock chip. Replacement requires soldering. The user should
return the IPC-623C to MultiTech Systems for repair if the clock
fails.
