4.1 HLTH LED is Red
This section describes strategies for troubleshooting a red HLTH LED.
Note
For information on LED flash codes, refer to Section A.3,
Fatal Hardware Self-Test Flash Codes.
If the HLTH LED is red, the channel is not running or there has been a firmware run-time error.
Check the WdTout bit (refer to Table 10, Control Register Bit Descriptions) to determine
whether or not there has been a watchdog timeout, and consult the appropriate firmware
manual if necessary. If you continue to experience difficulties, refer to Section 4.4,
General Troubleshooting.
Note
The firmware must be reloaded to restart the channel.
