Is it possible to set up M580 Hot Standby with mismatched PV and RL versions?

Issue
When the M580 CPUs are received, the hardware versions might not match.

Product Line
M580

Resolution
The PV and RL versions do not need to match in order to use the M580s in a Redundant Configuration. It is important that the firmware loaded into the M580s does match.

If it does not match, Unity Loader (for firmware V3.20 and lower only) can be used to load the latest or matching firmware. https://www.se.com/us/en/download/document/Unity_Loader_V140_SP1/

For the newer V4.xx firmware the EADM tool must be used for upgrade/matching (can also be used with older versions). https://www.se.com/us/en/download/document/EADM/

If it becomes necessary to run mismatched firmware the ECPU_HSBY_1.FW_MISMATCH_ALLOWED component can be set to allow this until the firmware can be matched. This component can be found in the ECPU_HSBY_1 Device DDT variable.
