How to install ASRock Rack 1U4LW-ROME/2T Barebone System

Note: This is a barebone system. Ensure you have a compatible AMD processor, DDR4 memory modules, storage drives, and a suitable power supply before starting installation.

Step 1 — Prepare the motherboard and CPU: Install the compatible AMD processor into the Socket LGA-4094, following the manufacturer’s torque specifications. Apply thermal paste as required and attach the processor cooler if it is not included with the barebone kit. Verify the CPU is seated correctly and that power delivery components are secured for reliable operation.

Step 2 — Install memory modules: Insert DDR4-3200 memory modules into the 8 DIMM slots, observing recommended population guidelines to maximize memory bandwidth and channel efficiency. Ensure modules are fully seated and locked in place to prevent RFI and thermal issues during operation.

Step 3 — Add storage drives: Mount your 3.5" drives into the four front bays and connect SATA power and data cables to the RAID controller or backplane as applicable. Confirm cable routing minimizes airflow obstruction and reduces vibration for longevity and performance.

Step 4 — Connect management and network interfaces: If not pre-connected, attach the management links for the ASPEED AST2500 interface and connect the RJ-45 network cable for standard management and data access. This ensures you can access remote management features from the outset for BIOS, firmware, and OS deployment tasks.

Step 5 — Rack mounting and power: Slide the assembled barebone chassis into a standard 19" rack, secure it with rack ears or screws, and connect a compatible power supply (not included with many barebone configurations). Power on and proceed to BIOS configuration to set boot order, RAID mode, and other platform preferences before installing your operating system.

Step 6 — BIOS and RAID configuration: Enter the system BIOS to configure processor settings, memory timing, and PCIe device mapping as needed for your workload. If you plan to use the RAID features, configure the SATA controller to the desired RAID level and initialize your storage array prior to installing the OS.

Step 7 — Operating system deployment: Install your preferred operating system and drivers, ensuring compatibility with the ASRock Rack chassis and the AMD processor. After installation, apply firmware updates and RAID controller updates as recommended by ASRock Rack to maintain performance and security.

Maintenance tips: Keep firmware and BIOS updated, monitor drive health and temperatures, and maintain unobstructed airflow around the front drive bays and rear expansion area. Use high-quality cooling solutions and a clean power supply setup to maximize uptime in data-center environments.
