Interpreting Error Beep Codes - Digital Equipment 3300R Service Manual

Power-Up Diagnostics and Display

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.
