criteria listed, and/or be
similar to past values.
What should I do? What is a good result?
Confirm power. Power LED illuminated.

indicated.
What does a good
result mean?
CCU has adequate
powering. Go to Test B.

12 Troubleshooting
What if I do not get a good result?
An increase in retry rates is potentially an
indication of an interferer at the CCU. If the
number of EUMs is small, a specific EUM-link
problem could be degrading this statistic, so
further analysis may be warranted at the EUM
link level.
What if I do not get a good result?
Check main AC power to CCU AC-DC
adaptor. Check AC-DC adaptor power output.
Correct or replace, as required.
-
Correct the configuration and retest. If system
is now functional, review personnel access
permission to CCU.
Suspect CCU hardware.
Check cabling, upstream equipment.
Suspect CCU hardware.
Go to Test K. Verify RF system at the CCU. If
a captive EUM is available, see TIP I.
Go to Test K. If a captive EUM is available,
