Table 6–4: Failure symptoms and possible causes (Cont.)
Symptom
Possible cause(s)
Diagnostic errors
H
Remove all electrical and optical modules from the
instrument, then diagnostics again. If the instrument passes
diagnostics, check for the electrical and optical module
that is causing the failures. The run diagnostics again.
H
If the instrument fails the diagnostics without the installed
modules replace the Acquisition assembly. The run
diagnostics again.
Compensation errors
H
Remove all electrical and optical modules from the
instrument, then run compensation again. If the instrument
passes compensation, check for the electrical and optical
module that is causing the failure.
H
Verify that each module is completely installed into the slot.
If the instrument still fails compensation, replace the
Acquisition assembly.
Modules not recognized
H
Module firmware incompatible with mainframe software
version.
H
Faulty module. Refer to appropriate module service manual
for further troubleshooting information.
H

H
Replace optical cables.
H
Replace Optical assembly or Acquisition assembly.
80C0X modules; poor noise
performance
H
Male fiber-fiber connections need to be cleaned. Refer to
Table 6–1 on page 6–3.
80C0X modules; frequency
response exhibits a steep
negative “droop” in its plot.
H
Bad internal O/E RF amplifier de-coupling. Check tightness
of all rigid cable interconnect.
BIOS error messages
H
Refer to the BIOS error message table.
Instrument locks up
H
Power down the instrument, then restart.
H
Replace the NLX assembly.
H
Replace the Power PC circuit board assembly.
