Twinax Operation
Dialing the diagnostic test number into the
"ADDRESS" switch selects the diagnostic
routines. Powering up the printer executes
them. (See NOTE).
You may change the "ADDRESS" switch
while the diagnostic is running (printing) to
step to another diagnostic. (See Table 8 )

Make sure the host twinax cable is not
attached to the "Smart T" twinax auto-
termination cable, while running
diagnostic 9. This will result in system
errors and possibly cause a proc-check
on your system.
The "Smart T" supplied with the MPI feature
must be attached to the MPI for all twinax
diagnostics. Remember, it must not be
attached to the host System when running
diagnostic 9.
