Practical considerations and pitfalls

• Firmware compatibility: Always match the key instructions to the iRMC firmware version — upgrading/downgrading firmware may require reissuing keys.
• Hardware changes: If you replace the motherboard or iRMC module, the original license might not transfer; contact Fujitsu for re-activation guidance.
• Security: Treat license files/keys as sensitive — they’re part of your management plane. Store them securely and avoid exposing them in public repositories or emails.
• Legitimacy: Avoid third-party “cracked” keys; they risk firmware corruption, lack of vendor support, and legal issues. Use Fujitsu-authorized channels.
• Backup: Keep a record of license entitlements, purchase receipts, and the license file in a secure vault so you can restore after hardware or firmware changes.

• Invalid license key: Ensure that the license key is entered correctly, and that it has not been used on another server.
• License key not recognized: Verify that the iRMC S4 firmware is up-to-date and that the license key is compatible with the current firmware version.
