  • Internal ports: 2 PCIe 3.0 NVMe x4 internal ports.  

• Expansion: 4 PCIe 3.0 “x24” slots (i.e., full-height riser lanes) for PCIe boards. 

• Networking & Management:

  • Dual 10GBase-T LAN ports (via C622).  

  • On-board IPMI (AST2500 BMC) for remote management. 

• I/O (Back Panel):

  • 1 VGA port. 

  • 4 USB 3.2 Gen 1 ports (rear). 

  • 1 USB 2.0 port (Type A).  

  • 1 serial (COM) port. 

• Additional Features:

  • Fan headers: up to 10 × 4‐pin fan headers. PWM fan speed control. 

  • System health monitoring: voltage, temperature, fan speeds; supports features like UID/remote UID LED, chassis intrusion header, etc.  

• Intended Use / Systems: This board is designed for Supermicro “SuperServer” chassis such as SYS-4029GP-TRT, SYS-4029GP-TRT2, SYS-4029GP-TRT3, SYS-6049GP-TRT etc. 

• Note: Because it is a proprietary board, chassis compatibility and specific wiring (power connectors, backplane, etc) must be verified. The manual states “designed to be used in an SMCI‐proprietary chassis only”.
