Basic Troubleshooting Procedures
This section shows you how to diagnose and solve basic
problems in the MERLIN II system. It also provides you
with the procedures for making an on-line module swap in
a Release 3 system.
Most of the troubleshooting procedures are based on
identifying the symptom, determining whether it is
hardware or software related, isolating the problem to one
of the areas indicated in Figure 4-1, and replacing
individual components in that area with components that
are known to be working until the cause of the problem is
identified and solved. If the problem lies with
administration or programming, determine the correct
procedure, then administer the system or program the
voice terminals accordingly. Tie line troubleshooting is
presented separately and is based on your being able to
test individual ports to determine if they are functioning
properly.
Problems that go beyond those caused by faulty but easily
replaced components should be referred to the equipment
supplier. Refer any problems involving the outside lines
to the serving telephone company.
The following troubleshooting checklist is provided to
guide you through the necessary steps to troubleshoot a
system. When a problem arises with the MERLIN II
system, be sure to check first the items listed under
“General Operating Condition’ in this section. If none of
those items are the source of the trouble, go on to
“Procedures for Specific Symptoms.” If the problem is not
described under that heading, or if none of the tests reveal
a specific problem, proceed to “General Tests” before
calling the equipment supplier.
