To upgrade to firmware version 3.0 or later, the only supported method is the Secure NMC System (SNS) Tool, which can be downloaded from www.se.com/secure-nmc or by searching for SFNMC3FMTSUCAN. To access the firmware in the software, a valid Secure NMC subscription is required. For more information, see the SNS Tool User Guide.

If you downgrade from firmware version 2.4+ to a firmware version lower than 2.4, this will cause the card to be formatted, erasing all security certificates, encryption keys, configuration settings, and the event and data logs.
