Issues might arise when operating Trellix ESM in FIPS mode.
Can't talk to the Trellix ESM
Check for an error condition on the Trellix ESM FIPS Self-test page.
If a single digit 0 is displayed, indicating that the device has failed a FIPS self-test, reboot the Trellix ESM device and attempt to correct the problem. If the failure condition persists, contact Support for further instructions.
If a single digit 1 is displayed, the communication problem is not due to FIPS failure. Contact Support for further troubleshooting steps.
Can't talk to the device
If there is a status flag next to the device on the system navigation tree, place the cursor over it. If it says FIPS Failure, contact Trellix Support by going to the support portal.
Follow the description under the Can't talk to the Trellix ESM issue.
