Troubleshooting Controller Circuit Pack
After power up, or after a reset, the multicolor LED (Located to the right of the MCR2 board)
will be RED while self diagnostics are in progress (which will take about 10 seconds). If all
diagnostics pass, the red LED will change to green. If failures are detected during diagnostics the
LED will change to Amber. 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 change to amber. When a failure occurs, perform the following steps.
Step Action
1 Press the reset switch (System Reset, located to the right of the serial port connector at
the bottom of the MCR1 board). 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 connector pins when installing optional equipment, etc. If the
diagnostics did not pass, or if the problem reoccurs, go to the next step.
2 Remove all optional circuit packs then again press the reset switch on the MCR1
board. If the problem is not resolved, proceed to the next step. If all diagnostics pass,
install optional packs one at a time, verifying operation after each.
3 Replace the MCR1/MCR2 boards and verify the failure is resolved before installing
and connecting any optional circuit packs.
Modem and Data Switch Cards
The intelligent option boards (Modem and Data switch) are diagnosed by the microprocessor. If
problems are detected the option board’s amber LED is lit, otherwise the green LED is lit. If the
amber LED is lit, first reset the MCR1 board and see if the problem clears. If the problem
reoccurs, replace the option board.
