Symptoms

CEM3 is rebooting/resetting/boot looping on its own

Explanation of Issue

There are several reasons why a CEM3 would be boot looping:

Test switch (S3) failure

Most CEM3s stuck in a boot loop or resetting at random is caused by a failure of the test switch

Firmware corruption

Uncommon, but can happen. A failed update and unintentional resets during the firmware update process can certainly cause this issue. May sometimes be related to a test switch failure

Boot line corruption

Rare. It is unknown what can cause the boot line to be corrupted, but may be related to a test switch failure
