26 Chapter 3 Hardware troubleshooting
The dbg128.exe is an extremely powerful tool designed for debugging the
MPB96 board. It can replace all the preceding tools and provide full control
over all the MPB96 registers and memory.
Windows and CallPilot hardware troubleshooting
Trouble symptom Action
The system beeps, but
seems to be running
properly and taking calls. This is a RAID card beep indicating that one of the drives does not
function properly. Do not shut down the system.
• Open the MegaRAID Client (CallPilot 2.x) or Power Console
Plus (CallPilot 3.x) utility, and check which drive is marked as
Dead.
• Rebuild the drive marked as Dead.
If the rebuild is unsuccessful, ensure that the other drive is working,
then shut down the system and replace the drive marked as Dead.
The system displays a blue
screen with the following
message:
Hardware
Malfunction, please
contact your H/W
vendor.
The system does not take
calls.
Check the release of the MPB96 board. The blue screen appears
if the MPB96 board release is 5 or earlier, and the version of the
system BIOS is other that P07, build 64.
If the MPB96 board release is 6 or later, the system BIOS release is
irrelevant.
Update the MPB96 board to release 6 or later to solve this trouble.
All DSP diagnostics fail at
system startup. Shut down the server and open the lid. Turn on the server and
check if the PCI LED on the MPB96 board is still on after startup.
If the LED is still on, then shut down the server, reseat the board,
and then turn on the server again.
• If the LED is still on, the board is defective and must be replaced.
• If the LED goes on and then off, but the DSP and CTbus
FPGA LEDs are still on after the system booted completely to
the operating system, then check the HAL and ensure that all
its components are working properly. If the HAL components
function properly, then at least one of the ctbus.mcs or dsp.mcs
files is corrupted. Replace these files and reboot the system. If
the PCI LED still stays on, then the MPB96 board is defective
and must be replaced.
