Yes, it is that simple—and that risky. For the vast majority of Fujitsu PRIMERGY servers manufactured in the last decade, the factory username and password are both admin . For very old servers (e.g., PRIMERGY TX300 S5, RX200 S5), the default pair was also admin / admin . There were no documented variations. The "User" vs. "Admin" Distinction Some iRMC firmware versions create a second default user:
Unlike some competitors that randomize default passwords per device (e.g., printed on a tag), Fujitsu has historically used static, well-known defaults . Default Credentials for 90% of Fujitsu iRMC (S3, S4, S5) | Field | Value | | :--- | :--- | | Username | admin | | Password | admin | fujitsu irmc default password
A: Yes, as of 2025 firmware releases, the factory default remains admin / admin . Fujitsu relies on administrators to change it during deployment. Conclusion: Default is for Setup, Not for Life The Fujitsu iRMC default password — admin / admin —is a lifeline for initial configuration and recovery. But leaving it unchanged is an invitation to compromise. Every day that default credential remains active on a network-accessible server, you are betting your security posture on the hope that no attacker scans for it. Yes, it is that simple—and that risky
Introduction In the world of enterprise IT, remote management controllers are the silent workhorses that keep data centers running. Fujitsu’s integrated Remote Management Controller (iRMC) is a powerful tool embedded in Fujitsu PRIMERGY servers, RX series, and other enterprise hardware. It allows system administrators to perform out-of-band management—monitoring temperatures, reinstalling operating systems, power cycling servers, and troubleshooting BIOS issues, all without physical access. There were no documented variations
