How to install ASRock Rack 1U4LW-X470 Barebone System

Before you begin, ensure you have compatible components, proper rack installation hardware, and a suitable power supply designed for data-center use. This guide outlines the essential steps to configure a functional rack-ready server using the ASRock Rack 1U4LW-X470 Barebone System.

Step 1: Prepare the chassis and rack. Mount the 1U chassis in your rack using the provided rails and screws. Connect the power supply, network cables, and management connections per your data-center practices. Verify that the rails are secure and that there is adequate clearance for airflow around the chassis.

Step 2: Install the CPU. Access the motherboard inside the barebone, locate the Socket AM4 socket, unlock the lever, and align the processor with the socket markings. Carefully seat the CPU, then secure the lever. If you plan to install a CPU cooler, follow the cooler’s installation instructions to ensure proper contact and clearance within the 1U space. Although this is a barebone, the right processor choice and cooling solution are critical for sustained performance under load.

Step 3: Install memory. Insert DDR4 DIMMs into the four memory slots in the correct seating order. Ensure that modules are fully seated and that the latches are securely engaged. For best stability, use identical memory kits across all slots and adhere to the manufacturer’s guidelines for voltage and timing (DDR4-3200 in this configuration). The 1U4LW-X470 supports up to 128 GB, providing ample headroom for virtualization hosts, caching roles, or small-scale databases.

Step 4: Add storage. Install your 3.5" drives into the four drive bays, securing them with screws as required. If you intend to use NVMe or PCIe-based storage, install the appropriate adapters or add-on cards that are compatible with the NVMe controller and available PCIe slots. For SATA RAID configurations, enter the BIOS/UEFI to configure RAID mode and preferred levels, then connect SATA cables to the drives. Plan your storage topology to balance capacity, performance, and redundancy according to your workload profile.

Step 5: Connect management and networking. Attach the RJ-45 network cable(s) to the system’s Ethernet ports and connect the ASPEED AST2500 management controller to a dedicated management network if you plan remote administration. Power up the system and access the management console to configure IP settings, user accounts, and remote monitoring features. Use the BMC interface provided by the AST2500 to monitor health, temperatures, and fan speeds, and to perform remote console access if required.

Step 6: BIOS/firmware and OS setup. Update the BIOS and BMC firmware if newer versions are available to ensure stability and support for new hardware revisions. Configure boot order, memory profiles, and any RAID or storage controller options you plan to deploy. Install your preferred operating system or virtualization hypervisor, then create and attach your storage resources within the OS. Run basic hardware diagnostics and verify network connectivity to confirm the system is ready for production workloads.
