Description: I/O Module firmware revision number.
What is smMainApp3VpdRevisionNumber?
This OCTET STRING is the revision number of the I/O (switch) module's main application firmware. An admin reads this revision number to confirm all switch modules across the chassis are running the same firmware revision before relying on identical failover behavior between them. For example, finding one switch module reporting a lower smMainApp3VpdRevisionNumber than its peers tells the admin which specific module still needs the firmware update applied.
