How to install Asus P11C-I Server Motherboard

Before you begin, prepare your chassis, power supply, CPU, memory, and any storage devices. Power down fully and discharge static electricity. Follow these steps to install the Asus P11C-I into a compatible Mini ITX chassis:

1) Prepare the chassis and standoffs: Install the appropriate motherboard standoffs in the chassis to align with the Mini ITX mounting holes. Ensure there is clearance for the CPU cooler, memory modules, and any expansion cards you plan to add.

2) Install the processor: Insert a compatible Intel Xeon E-Series processor into the LGA 1151 socket with careful alignment of the notches. Apply an appropriate amount of thermal interface material if your cooler requires it, then secure the heatsink or CPU cooler according to the cooler’s instructions.

3) Install memory: Insert DDR4 ECC or non-ECC UDIMMs into the memory slots, ensuring correct orientation and full seating. Refer to the motherboard manual for recommended slot population for best performance and memory interleaving.

4) Attach storage: If you plan to use the M.2 slot, install an M.2 SSD with the notch and screw at the correct angle. Connect any additional SATA drives or expanders as needed, ensuring data cables are routed neatly to avoid obstruction to fans and components.

5) Connect power and peripherals: Connect the 24-pin ATX power connector and the CPU power connector as required, then attach the case USB connectors and the USB 3.1 cables to the appropriate headers. Mount any network cables to the dual Gigabit LAN ports and connect other peripherals such as keyboards, mice, and display devices as needed for BIOS setup.

6) BIOS and first boot: Power on and enter the BIOS/UEFI to verify CPU recognition, memory counts, and boot order. Configure settings for Xeon E-Series performance, memory timings (if necessary), and boot devices. Save changes and reboot to install your operating system or hypervisor. If you plan to use virtualization or a NAS OS, follow their installation recommendations and drivers for network and storage controllers.

7) Final checks and testing: Run basic stress tests to ensure the CPU, memory, and storage are operating correctly under load. Confirm network throughput across both Gigabit LAN ports, verify USB ports are functioning, and monitor temperatures to ensure adequate cooling in your chassis. If you require remote management, set up any IPMI or management features supported by the board, and ensure firmware updates are applied to maximize reliability and security.
