The **M2AS1-5312-R2/CE** is a specialized high-performance computing component, primarily recognized as a server-grade motherboard or a specific node assembly used in cloud computing and data center infrastructure. --- ## 1. Core Technical Specifications This component is designed for high-density environments. Below are the primary electronic characteristics: | Component | Specification | | :--- | :--- | | **Form Factor** | Proprietary High-Density Blade / Node | | **Processor Support** | Intel Xeon Scalable Family (Typical) | | **Memory Slots** | 8x to 16x DDR4 DIMM Slots (ECC Registered) | | **Storage Interface** | NVMe (M.2) and SATA 6Gb/s Support | | **Networking** | Integrated 10GbE or 25GbE SFP+ / RJ45 | | **Expansion** | PCIe Gen 3.0 / 4.0 x16 Slots | --- ## 2. Key Electronic Sections ### A. Power Management (VRM) The board utilizes a multi-phase **Voltage Regulator Module (VRM)** to convert 12V DC input from the server backplane into the low-voltage, high-current power required by the CPUs and RAM. It features: * Solid-state capacitors for high-temperature stability. * Digital PWM controllers for precise power delivery. ### B. Management Controller (BMC) It typically integrates an **ASPEED AST2500/2600** chipset. This is a "computer within a computer" that allows: * IPMI 2.0 support for remote power cycling. * KVM over IP (remote desktop access). * Sensor monitoring (Voltage, Fan Speed, Temperature). ### C. Connectivity and I/O The "R2/CE" designation often refers to specific revisions for compliance (CE) and hardware refreshes (R2). * **Chipset:** Intel C621/C622 Series. * **TPM:** Trusted Platform Module header for hardware-level security and encryption. --- ## 3. Maintenance and Identification Code If you are looking at the PCB, you will find several critical markings: * **Revision 2 (R2):** Indicates a hardware update from the original design, often improving signal integrity or component compatibility. * **CE Marking:** Confirms the electronic assembly meets European safety, health, and environmental protection requirements. * **M.2 Support:** The "M2" prefix usually denotes primary support for M.2 NVMe boot drives, reducing the need for cabling. ---
