7.2LED Display Codes

LED displays appear on the backplane of the SuperTrak66 controller.

NOTE: The LEDs on the backplane of the SuperTrak66 controller go through various patterns throughout the power-on and initialization process. However, only three different conditions remain constant.

Event: LEDs on the card backplane turn on a few seconds after system power-on and show a pattern of ON-OFF-OFF-ON (1001).

Cause: This is the “normal” condition of the LEDs after power-on indicating that the IxWorks O/S loaded properly on the controller, and that the cache memory SIMM is functioning. This pattern requires no special attention.

Event: LEDs on the card backplane turn on a few seconds after power-on and move in a back and forth pattern.

Cause: This is the operational mode of the LEDs after the card has been initialized at power up. This indicates that the HDM thread is loaded and running correctly.

Event: LEDs on the card backplane turn on a few seconds after system power-on and show a pattern of ON-OFF-ON-OFF (1010).

Cause: This condition is caused by the SIMM memory on the SuperTrak66 controller. It is either not installed correctly, has problems with the connections, or may be an unsupported type of memory SIMM. Make sure the SIMM is seated correctly before trying an alternate memory module to correct the problem.
