Description
RAID controller LEDs
BMC beep codes
The main board used in the 703t server includes a baseboard management
controller (BMC) that provides monitoring, alerting, and logging of critical
system information obtained from sensors embedded on the board.
The BMC generates beep codes when it detects failure conditions. Each
digit in the code represents a sequence of beeps.

Information
started and the CallPilot diagnostic screen has appeared, then
the MPB96 board is defective or the DSP and NTBus drivers
do not function properly.
• The CTbus FPGA Done LED (the farthest from the card I/O
bracket) works in tandem with the DSP FPGA Done LED and
turns on and off at the same time.
The RAID controller has one red LED and eight small LEDs at the
back. When the card works properly, the red LED comes briefly on
at startup indicating that the card was accessed for detection. At the
same time, all eight LEDs at the back of the card come on, and then
half of them turn off and stay off. Four lit LEDs at the back of the
card indicate that the card works properly. If all eight LEDs stay on
after startup, the card was not detected or is defective.
Reason
Front panel CMOS clear initiated
Fault resilient booting failure (processor failure)
No processor installed or empty processor socket 1
Processor configuration error (for example, mismatched voltage identifications
and empty processor socket 1
Front-side bus select configuration error (for example, mismatched BSELs)
Power fault: dc power unexpectedly lost
Chipset control failure
Power control failure
