Description	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.
RAID controller LEDs	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.

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.
Beep code	Reason
1	Front panel CMOS clear initiated
1-5-1-1	Fault resilient booting failure (processor failure)
1-5-2-1	No processor installed or empty processor socket 1
1-5-2-3	Processor configuration error (for example, mismatched voltage identifications
	and empty processor socket 1
1-5-2-4	Front-side bus select configuration error (for example, mismatched BSELs)
1-5-4-2	Power fault: dc power unexpectedly lost
1-5-4-3	Chipset control failure
1-5-4-4	Power control failure
