After power up, or after a reset, the green and amber LEDs will both be
lit while self diagnostics are in progress (which will take about a 30
seconds). If all diagnostics pass, the amber LED will extinguish and the
green LED will remain lit. If failures are detected during diagnostics the
green LED will extinguish, and the amber LED will remain lit. If a
terminal is attached to the local port during diagnostics, the diagnostic
messages will show which test failed. During normal operation if a
failure occurs the green LED will extinguish and the amber LED will
light. When a failure occurs, perform the following steps.
1. Press the reset switch on the front of the BJH circuit pack. If all
diagnostics pass, it is possible that some type of “one time”
abnormality occurred to cause the failure, such as hot-insertion of
option boards, shorting backplane pins when installing optional
equipment, etc. If the diagnostics did not pass, or if the problem
reoccurs, go to the next step.
2. Replace the BJH circuit pack and verify the failure is resolved. If
the problem remains, put the original BJH circuit pack back in the
controller and go to the next step.
3. Remove all option cards and press the reset switch on the BJH. If
the problem is still present, replace the BJJ power board. If the
problem is resolved insert the option boards, reset the controller,
and verify proper operation. If the problem remains put the
original BJJ power board back in the controller and go to the next
step.
4. Insert the option boards one at a time, while resetting the
controller after each board is installed and looking for improper
operation. Replace the option board which causes a failure, insert
the remaining option boards, and verify proper operation.
BJJ Power Board The LEDs on this board work independent of the microprocessor.
Analog comparators monitor the levels of the three power supplies. If no
problem exists, the green LED is lit, if one of the supplies is out of range,
the amber LED is lit. The test jacks on the front of the board can be used
to verify the supply voltages. The three voltage levels should be:
