Internal LEDs
Description	Information
MPB96 board LEDs	The three red LEDs at the top of the MPB96 board are visible through
	the grill at the back of the server.
	• The PCI FPGA Done LED (the closest to the card I/O bracket)
	comes on at startup and turns off immediately. This indicates
	that the board works properly and was detected correctly by the
	system. If this LED stays on after the startup, the card is defective
	and must be replaced.
	• The DSP FPGA Done LED comes on at startup and stays on
	until the CallPilot drivers are loaded and the diagnostic screen
	appears. If the LED stays on after the operating system starts and
	the CallPilot diagnostic screen appears, 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.

POST beep codes

If an error occurs before video initialization, the POST emits beep codes that indicate errors in hardware, software, or firmware.

	A beep code is a series of separate tones, each equal in length. Record the
	beep code sequence before calling Nortel technical support.
Beep count	Description
1, 2, or 3	A Memory error occurred. Reseat the memory or replace the DIMMs with
	known good modules.
4 – 7 or 9 – 11	A fatal error occurred and indicates a possible serious system problem.
	Remove all the add-in cards and restart the system. If the error still
	occurs, contact Nortel support. If the beep codes are not generated after
	you remove the add-in cards, insert the cards one at a time, booting the
	system between each card addition, until the beeps again occur to reveal
	the malfunctioning card.
8	A problem with the onboard video card occurred indicating a fault on the
	server board.

BIOS error messages

When a recoverable error occurs during the POST, the BIOS displays an error message describing the problem.
