The instrument control computer is designed to operate Illumina sequencing systems. Do not consider it a general-purpose computer. For quality and security reasons, do not use the control computer for web browsing, checking email, reviewing documents, or other unnecessary activity. These activities can result in degraded performance or loss of data.

Illumina instrument control computers running Windows 7 support one account type: Administrator. Illumina recommends upgrading the current software version to be able to use the User account type.

Only use the Administrator account type when it is required.

You are required to set a password upon initial setup of your system. The following table identifies the required password policies for the control computer.

Illumina does not store or maintain customer login credentials, and unknown passwords cannot be reset. An unknown password requires that an Illumina representative restore the factory default, which removes all data from the system and extends the necessary support time.

1. Press Ctrl+Alt+Delete, and then select Change a password.
2. In the Old password field, type the default password.
3. In the New password field, type the new password.

For security, the password must be at least 10 characters long, comply with local policies, and contain numbers, letters, and symbols.

4. In the Confirm password field, reenter the new password.
5. Press Enter to confirm the reset and return to the desktop.
6. In the search box, type netplwiz, and then press Enter.
7. In the User Accounts dialog box, select the Users must enter a user name and password to use this computer checkbox.
8. Select Apply, and then select OK.

Illumina instrument control computers running Linux OS support three types of accounts:

• Root (super administrator)
• Ilmnadmin (administrator)
• Ilmnuser (user)

The Illumina Field Service Engineer initiates a password change for all three accounts after completing instrument installation. Update each password every 180 days, when prompted.
