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.
The system displays a blue screen with the following message: Hardware
Malfunction, please
•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.
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.
contact your H/W vendor.
The system does not take calls.
All DSP diagnostics fail at system startup.
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.
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.
