The error messages and descriptions
are
listed

If an error message is displayed, powerdown the
system and verify that the cable connectors
and
PC

are
properly
inserted.
If
the error message remains and
more information is needed to isolate the problem, refer
to
the
SADIE diagnostics in the System 8000 Hardware Reference
Manual.
When the problem is
isolated
to

power
down
and
replace
the
board.
Return the defective
board to the factory for repair.
NOTE
ZEUS is installed on disk at the factory.
If SPUD
runs
correctly, pressing START also activates the
automatic ZEUS boot-up procedures.
