Frequently Asked Questions - A2SDi-LN4F Supermicro
What processor is built into the Supermicro A2SDi-LN4F?
The board uses an Intel Atom C3758 system-on-chip with 8 physical cores at 2.2 GHz. No CPU installation is needed; the cooling solution is already attached.
How much memory can I install?
The board has four DDR4 ECC UDIMM slots. With 32 GB modules, you can reach a maximum of 128 GB. Use DDR4-2400 or lower for reliable operation.
Does it support 10 Gigabit Ethernet?
No, this model provides four Gigabit Ethernet ports. If you need 10GBase-T networking, choose the HLN4F variants from Supermicro.
Can I use a standard computer power supply?
The A2SDi-LN4F accepts 12V DC power input. You can use a suitable AC-DC adapter or a PSU capable of delivering clean 12V power with sufficient current (at least 5A recommended).
Does it support ECC memory?
Yes, it requires DDR4 ECC UDIMM memory. ECC is strongly recommended for data integrity in server and network appliance applications.
Can I install a PCIe graphics card?
The single PCIe 3.0 x8 slot can accept a low-profile GPU or network card. It is not suitable for high-power gaming graphics cards; verify the total power budget.
How do I access remote management?
Connect to the IPMI LAN port or use the BMC network interface. The Aspeed AST2500 controller provides IPMI 2.0, KVM-over-LAN, and virtual media access via a web browser.
What operating systems are compatible?
It works with Windows Server, Linux distributions, VMware ESXi, FreeBSD, and other embedded operating systems. Download the latest LAN and BMC drivers from Supermicro's website.
Is the motherboard easy to clean?
Use dry compressed air to remove dust from the heatsink and connectors. Never apply liquid cleaners while the board is powered on. Always disconnect power and use an anti-static wrist strap.
Can I replace the CPU or repair the motherboard?
The Intel Atom SoC is soldered directly onto the board, so the CPU and chipset are not replaceable. Only memory, storage, the CMOS battery, and expansion cards are user-serviceable.
