how to install ASRock Rack 3U10G-F/C621

• Plan your deployment by confirming rack space, power availability, and network topology. Ensure your data center has appropriate cooling, rack rails, and cable management to support a 3U chassis with dual CPUs and memory expansion.
• Install the chassis into the rack using the included rails, ensuring secure mounting and proper alignment with front-panel access for easy maintenance and service access. Verify cage nut placements and cable routing clearances before powering on.
• Prepare the processor(s) and memory. Insert the dual CPUs into their sockets according to the manufacturer’s guidelines, apply the appropriate thermal interface material if required, and seat the heatsinks securely. Then populate the 16 DIMM slots with DDR4 memory modules, following the recommended population sequence to maximize channel interleaving and memory bandwidth.
• Configure storage options. Connect SATA drives to the Serial ATA/600 controller, install the M.2 SSD or NVMe drive into the M.2 slot, and secure any required power or data cables. Plan for future expansion by leaving space available for additional drives and future M.2 modules as workloads grow.
• Power up and access the system BIOS/UEFI. Begin with baseline configuration: set boot devices, enable necessary virtualization features, configure memory performance profiles, and set any required PCIe slot priorities. Update firmware and BIOS as needed, and implement enterprise settings such as NIC teaming, RAID configuration, and power management policies tailored to your workload.
• Install an operating system or virtualization platform of choice. Use boot media appropriate for your environment (USB, PXE, or internal USB) and complete initial setup. Verify drive health, memory integrity, and CPU temperatures under load to ensure stable operation. Finally, configure remote management tools and monitoring agents to maintain visibility and health checks across your server stack.
