4.1 COMM LED is Red
This section describes strategies for troubleshooting a red COMM LED.
Note
For information on LED flash codes, refer to Section A.1.2,
Fatal Hardware Self-Test Flash Codes.
If the COMM LED is red, the card is not running or there has been a firmware run-time error.
Check the WdTout bit (refer to Table 9,
Control Register Bit Descriptions
) to determine
whether or not there has been a watchdog timeout, and consult the firmware reference guide.
If you continue to experience difficulties, refer to Section 4.3,
General Troubleshooting
.
Note
The firmware module must be reloaded to restart the card.
