Product Introduction
1.1 Product Overview

This is a dual-CPU motherboard designed around the Intel Xeon Gold series processors, compliant with commercial EEB motherboard specifications, specifically engineered for high-performance, fully ruggedized servers. It integrates 64GB DDR4 memory with surface-mounted memory chips and provides abundant high-strength I/O interface connectors (6 SATA 3.0, USB 3.0, Gigabit Ethernet ports, VGA, and RS232 interfaces). Featuring high reliability, full ruggedization, high performance, and rich interfaces, this motherboard serves as the core platform for high-reliability, fully ruggedized hyper-converged computing servers.

Motherboard dimensions: 304.8*295*2.4mm.

2.14 KVM Functionality

The motherboard supports KVM connectivity, enabling human-machine interaction for server operation and management via KVM.

Supports KVM over IP—remote management-capable KVM switch with remote monitoring capabilities.

2.15 Health Diagnostics and Monitoring

Health diagnostics function:
- Reports status information via Simple Network Management Protocol (SNMP), capable of periodically sending self-check data to report server status including power state, availability, core parameters, fan status, etc.
- System maintenance functions support BMC system recovery and updates.
Web-based Management:
- Provides sensor monitoring, fan cooling control, power status monitoring, health log management, and server runtime status monitoring.
SNMP Remote Management:
- Offers real-time query interfaces for power state, temperature, voltage, fan status, power consumption, memory utilization, CPU usage, CPU temperature, used and remaining disk capacity, and RAID status.
- Also provides control interfaces for power on/off and fan speed adjustment.
SNMP Fault Reporting (higher-level motherboards can also retrieve the following information via "access"):
- Reports power state, temperature, voltage, fan status, power consumption, memory utilization, CPU usage, CPU temperature, used and remaining disk capacity, network connection status, RAID status, or fault information to a designated IP address.
- Provides O&M alarm message interface; when abnormal operation is detected, sends real-time alert messages in SNMP packet format to a specified address. Fault reports must include at least fault code, cause, impact, and recommended resolution.
