The VTrak E-Class products support hot plugging of a replacement controller.
If the replacement controller has a different firmware than the surviving controller, the following results are expected.
Ex10 family:
When the replacement controller has a different firmware than the currently running controller, the newly installed controller will go into Maintenance Mode due to a firmware mismatch.
Solution:
Flash the matching firmware onto the replacement controller.
Once the firmware are matching versions, start the VTrak with the original surviving controller. When the VTrak Ex10 is fully up and running, hot plug the updated replacement controller.
Hot plugging the replacement controller allows mirroring of all user/controller settings from the running controller to the newly installed replacement controller.
Ex30 family:
When the replacement controller has a different firmware than the currently running controller, the newly installed controller will have its firmware updated to match the surviving controller.
Solution:
The VTrak Ex30 family will automatically update the replacement controller's firmware to match the surviving controller. There is no need to manually flash the firmware onto the replacement.
Our Non-disruptive Image Update (NDIU)feature allows the replacement controller to load the firmware from the surviving controller and then reboot.
Upon reboot, the two controllers firmware will now match and the replacement controller will start normally and be fully operational
