2.1 Interpreting Error Beep Codes
If errors are detected at power-up, audible beep codes are emitted from the system.
For example, if the SROM code could not find any good memory, you would hear a
1-3-3 beep code (one beep, a pause, a burst of three beeps, a pause, and another burst
of three beeps).
Be sure to check that the CPU daughter board is properly seated in its connector if
errors are reported.
NOTE: A single beep is emitted when the SROM code completes successfully. The
console firmware then continues with its power-up tests.
The beep codes are the primary diagnostic tool for troubleshooting problems when
console mode cannot be accessed. Refer to Table 2-1 for information on interpreting
error beep codes.
