Isolating and correcting faults
Once familiar with the troubleshooting tools, begin troubleshooting Carrier
Remote IPE equipment. Based on whether Carrier Remote IPE equipment
has just been installed and is not yet operational, or it had previously been
operating correctly and is now faulty, it can be determined what might be
the most probable cause of failure.
Type of faults
Problems can occur in the following areas:
•
hardware
•
configuration
•
software
The type of faults to isolate and correct depends on whether faults occur
during installation or due to component failure in a previously operating
system. For example, in a newly installed system the fault can be in any or
all of the three areas. However, in a previously operating system the fault
is probably in the hardware.
Fault isolation steps
The following steps describe how to isolate system and Carrier Remote
IPE faults using the diagnostic tools described in this chapter:
1.
Observe and list the problem symptoms the system is exhibiting.
Typical symptoms can be: the Local Carrier Interface card or Remote
Carrier Interface card has its red LEDs turned on the Remote Carrier
Interface card faceplate display shows a fault code, some common
equipment or power supplies have their green LEDs turned off, some
of the common equipment or network cards display codes that indicate
faults.
2.
Note if Carrier Remote IPE was just installed and has not been
operating, or if it has been operating correctly and is now faulty. Based
on this, refer to "
below for lists of the most common problems.
3.
Take the action recommended by the fault isolation and correction
tables, which guide through fault isolation steps and recommend what
test procedures to use.
4.
If after following the diagnostic procedures Carrier Remote IPE still
does not operate correctly, contact the field service representative.
