How to install Intel RAID Controller RT3EX020E

Follow these general steps to install the RT3EX020E and configure a basic RAID-enabled storage setup. Always ensure you have working backups before modifying storage configurations.

1) Power down the computer and unplug the power cord. Open the computer case to access the motherboard and PCIe slots. Remove any clearance panels or brackets as needed to accommodate the expansion card.

2) Locate a free PCI Express slot compatible with PCIe 2.0 x2. Carefully align the RT3EX020E with the slot and gently press the card straight into place until it seats firmly. Secure the bracket with a screw to prevent movement.

3) Connect the internal SATA drives to the two SATA ports on the card. Route any cables neatly to maintain proper airflow and minimize cable strain. If you’re configuring multiple drives, plan your drive order and RAID layout before booting.

4) Replace the case cover, plug the system back in, and power on. Enter the system firmware or BIOS/RAID utility during boot to recognize the new expansion card. The ROM-based RAID management interface (and/or operating system drivers) will guide you through initial detection and configuration.

5) Initialize a RAID array if you plan to use RAID protection. Select the appropriate RAID level (noting this card supports a single RAID level) and follow the prompts to create the logical drive. After the RAID is configured, install or update the operating system as needed and install any required drivers or RAID management software for ongoing maintenance.

6) Boot into your operating system and verify that the drives are visible and the RAID array is healthy. Run any recommended diagnostics to confirm performance and reliability, and adjust caching policies or power settings for your workload as needed.
