Fujitsu Irmc Default Password May 2026

The server room was humming, a steady mechanical drone that usually felt like progress. But for

, it felt like a wall. He had just inherited a rack of Fujitsu PRIMERGY servers, and his first task was to configure the Integrated Remote Management Controller (iRMC). He opened his browser, typed in the IP, and stared at the login screen.

"Standard procedure," Elias muttered. He tried the classic combinations that every sysadmin knows by heart. Admin/password? No. Administrator/blank? Nothing.

He pulled up the Fujitsu documentation and found the answer: the default credentials for Fujitsu iRMC are admin for the username and admin for the password.

He typed them in, and the dashboard finally blinked to life. But Elias knew the story didn't end with a successful login. Leaving default credentials active is an invitation for trouble. Before he even checked the sensor logs, he navigated to the user management settings and updated the admin password to something complex and secure.

For those who find themselves locked out because the previous tech changed the "admin/admin" default, Elias knew there was a backup plan. As noted by technical guides on the Fujitsu PRIMERGY, you can use an IPMI tool from within the host operating system to reset the iRMC admin password without needing to reboot the entire server.

With the password secured and the dashboard open, the hum of the server room finally sounded like music again.

The default credentials for a Fujitsu iRMC (integrated Remote Management Controller) depend on the hardware generation of your

server. Older generations typically use a generic global password, while newer generations (S6 and later) utilize unique, device-specific passwords for enhanced security. Default Credentials by Generation iRMC S2, S3, S4, and S5 (all lowercase) (all lowercase) iRMC S6 (and newer) (all lowercase) Unique to each server.

Fujitsu no longer uses "admin" as a global default for these generations Where to Find the Unique iRMC S6 Password

If you have a newer server with an iRMC S6 controller, you can find the individual default password in two physical locations: System ID Card: A pull-out tag usually located at the front of the server fujitsu irmc default password

. The password is the complete line of text printed below the barcode (e.g., Admin-4CkNxNZqWoOK Top Cover Label:

For smaller servers that lack a System ID Card, a label with the default password is attached directly to the top cover of the chassis Important Security & Troubleshooting Tips Case Sensitivity: All iRMC passwords are case-sensitive Ambiguous Characters:

On printed labels, capital "I" (India) and lowercase "l" (lima) can look identical. If typing manually fails, Fujitsu recommends using a smartphone barcode scanner

on the System ID Card to capture the exact string without errors Forced Change:

Most newer iRMC versions will force you to change this default password immediately after your first successful login Resetting Credentials:

If the default password has been changed and lost, you may need to use the ServerView Installation Manager (SVIM)

via the host operating system to reset the iRMC to factory defaults Are you trying to a lost password, or are you setting up a server for the first time? Downloads - Fujitsu Support

Fujitsu Integrated Remote Management Controller (iRMC) provides out-of-band management for PRIMERGY and PRIMEQUEST servers. Access to this interface is secured by credentials that have evolved from static defaults to unique, server-specific identifiers. Default Credentials by Generation

The default username for nearly all Fujitsu iRMC generations is admin. However, the password varies significantly depending on the age of the hardware:

Legacy Systems (iRMC S2, S3, S4): Older systems often shipped with the static default password admin. The server room was humming, a steady mechanical

Modern Systems (iRMC S5, S6): Current servers use unique passwords to comply with modern security standards. Locating Unique Default Passwords

For modern servers, the unique password can be found in two physical locations:

System ID Card: A pull-out plastic tag on the front of the server containing a barcode and a password typically prefixed with "Admin-" followed by 12 characters (e.g., Admin-4CkNxNZqWoOK).

Chassis Label: On smaller servers where a card is not present, a label is attached to the top cover.

💡 Key Note: The entire string, including the "Admin-" prefix, constitutes the password. It is strictly case-sensitive. Resetting or Changing the Password

If the default password fails or has been forgotten, you can reset it through several methods. Organizations can also refer to the Fujitsu PRIMERGY Security Overview for broader server hardening strategies. Using IPMITool (Local OS Access)

If you have access to the server's operating system (Linux or Windows), use the ipmitool utility to reset the admin password directly. Command: ipmitool user set password 2 .

User ID 2: This is the default ID for the "admin" user on Fujitsu hardware. Using ServerView Installation Manager (SVIM)

If the OS is unreachable, boot from the ServerView Installation Manager ISO. Open an x-term window and execute the same ipmitool command to regain access. Guidance for this and other tools is available through Fujitsu Support Downloads. Password Complexity Requirements

Starting with iRMC S6, new passwords must meet strict criteria: Minimum length of 12 characters. Point iRMC to a central syslog server

Must include at least three of the following: lowercase letters, uppercase letters, digits, or special characters. Troubleshooting Common Issues

Character Confusion: Characters like capital "I" and lowercase "l" can look identical. Fujitsu recommends using a smartphone to scan the barcode on the ID card to retrieve the exact string.

"Unknown Error" at Login: On iRMC S6 (firmware 2.06S and lower), entering incorrect credentials may trigger a generic "Unknown Error" instead of a "Login Failed" message.

Manual Recovery: If you are using specialized hardware like the HyperScale appliance, you can find specific recovery steps on the Commvault Community. Peer-led technical discussions on Experts Exchange also provide legacy server support.

6. Centralized Logging (Syslog)

Scenario A: Older PRIMERGY Models (Fixed Defaults)

On older Fujitsu PRIMERGY servers, the iRMC often ships with a static, universal default password.

4. Remediation and Hardening Procedures

It is mandatory to change the default password during the initial server provisioning phase.

Method 2: iRMC Command Line (SSH)

  1. SSH to the iRMC IP (e.g., ssh admin@192.168.1.100).
  2. Enter the default password when prompted.
  3. Run the command: 
    set /system1/account1 password=YourNewStrongPassword
  4. Verify: 
    show /system1/account1

4.3. Automation (Redfish API)

For large-scale deployments, the password should be changed via the Redfish API standard, supported by modern iRMC firmware (S4/S5 and newer). A PATCH request to the Manager Account endpoint is required.

Example payload:

PATCH /redfish/v1/AccountService/Accounts/1
"Password": "NewStrongPassword123!"

2.2. Regional Variations (Europe/EMEA)

In some specific hardware generations or regions (particularly EMEA), Fujitsu has implemented a security measure where the default password is not static but is derived from the hardware serial number.

3. Attack Vectors & Exploitation

If the default admin/admin is active, an attacker can achieve full "BMC-level" compromise.
