Troubleshooting
Error Beep Codes
Table 4-4 shows error beep codes that you may encounter while using the Digital
AlphaStation 400 Series system. For example, if the SROM (serial read only memory)
code cannot find any good memory, you hear a 1-3-3 beep code (one beep, a pause, a burst
of three beeps, a pause, and another burst of three beeps).
Table 4-4. Error Beep Codes
Beep Code Meaning
1-1-4 (1) The SROM code could not read the DROM (diagnostic read
only memory) or flashROM headers, or (2) there was a checksum
failure.
1-2-1 (1) The DROM code detected a realtime clock (BQ3287) failure, or
(2) the realtime clock interrupt did not occur.
1-2-4 The SROM code detected a hard failure (for example, a Bcache
failure).
1-3-3 (1) The SROM code could not find 2 MB of good memory, or (2)
there was no memory available.
3-2-1 The DROM code was unable to read the header of the flashROM,
or the flashROM checksum failed. Therefore, the DROM code
attempted to boot from the floppy. The attempt failed because of
either: (1) no floppy in drive, or (2) no Alpha architecture boot
block on the floppy.
3-2-3 The DROM code was directed by the position of jumper J5 to load
the floppy, but there was no floppy in the drive.
3-2-4 The DROM code detected a failure with the keyboard or mouse
controller.
3-3-1 The DROM code detected a hard failure. Refer to the LEDs to find
exact location of failure.
Diagnostic LEDs
Your system contains eight diagnostic LED indicators located on the CPU module. The
LEDs indicate errors that occur during system initialization and power-on self test (POST).
Refer to the Digital AlphaStation 400 Series CPU Module Information for the locations of
the LEDs.
