7.4 Diagnostic Procedures
This section contains a set of diagnostic procedures which may be referenced directly or
used in conjunction with the Operational Problems first level diagnosis flow charts.
Each procedure starts with a description of the symptoms of the error class, followed by a set
of diagnostic actions which will allows the actual fault to be pinpointed more accurately. Once
this has been achieved it should be possible for the user to attempt to correct the fault.
7.4.1 Power Supply
Symptoms
No LEDs illuminated.
Diagnostic Actions:
1 Check there is power to the unit and the unit is switched on.
2 Check for fuse failure in the power feed or on the rear panel of the unit.
3 If still unable to locate the problem, the InterChange iQ 2000 unit must be
returned for repair.
7.4.2 Self Test Failure
Symptoms
The ’Power’ LED remains orange.
Diagnostic action:
The hardware self-test has failed.
Cycle the Power on/off switch to reset the unit. If the unit continues to fail the self test:
•
Contact your second line support engineers for assistance, if needed.
•
Return the failed unit for repair, with a note of the error reported by the
Vision iQ diagnostics.
The above procedure describes all that can be achieved on-site in the way of failures
diagnosed by the self test software.
7.4.3 Port Failure Alarm
Symptoms
When there is a Port Failure alarm, it is indicated by either (or both) P1 and P2 LEDs coming
on red.
