how to install Asus RS500A-E12-RS12U-12W12B

Follow these steps to assemble and deploy the Asus RS500A-E12-RS12U-12W12B barebone system in a data center rack. This guide assumes you are installing a single AMD EPYC 9004 processor and configuring memory, storage, and expansion cards as part of a standard enterprise deployment. Always consult your data center policies and safety guidelines before starting.

• Prepare the rack and chassis: Ensure the rack rail kits are installed and aligned. Verify power availability and grounding. Confirm that the chassis is clean, free of obstructions, and positioned for easy access to the front and rear panels.
• Install the processor into Socket SP5 LGA-6096: Open the processor socket, align the AMD EPYC 9004 CPU to the indicated orientation, and secure the latch. Apply an appropriate amount of thermal paste if required and attach the heatsink or cooling solution per the included guidelines. Ensure proper seating and clearance for airflow.
• Populate memory modules (up to 24 DIMMs): Insert DDR5 memory modules into the DIMM slots across the channels, following the manufacturer’s recommended population order for optimal performance. Verify that each module is fully seated and that memory is detected by the system during POST.
• Install storage devices: Add up to 16 NVMe drives in the designated NVMe bays and place up to 2 M.2 drives for OS or cache storage. Secure drives according to the chassis’ guidelines and ensure correct drive hot-swap or non-hot-swap configurations as required by your deployment.
• Install PCIe add-ins and GPUs (if used): Insert PCIe 5.0 expansion cards into the available slots. If using GPUs, mount single-slot GPUs as supported and secure with screws. Attach any required power or auxiliary connectors and verify physical clearance for airflow and cables.
• Connect power, networking, and management: Attach the power cables, connect OCP NICs if used, and ensure remote management features are accessible via the ASMB11-iKVM. Power on the system and enter the BIOS/UEFI setup to configure boot order and device recognition as needed.
• Initial boot and validation: Run POST checks, verify CPU, memory, storage, PCIe devices, and GPUs are detected, and apply any firmware or BIOS updates from ASUS support if available. Confirm that remote management is functioning correctly for ongoing administration.
• Software deployment and monitoring: Install your preferred operating system or hypervisor, configure networking, and begin deploying workloads. Use ASMB11-iKVM for ongoing remote monitoring, firmware updates, and health checks to ensure reliable operation.
