KB 508883 - Supermicro AS-4125GS-TNRT2 Server Expansion card Installation

The AS-4125GS-TNRT2 is a 4U rackmount server designed for high-density GPU configurations, and PCIe expansion. Expansion slots are managed via dedicated riser cards.

AOM-PTG-I2T-P is the riser card using in Supermicro AS-4125GS-TNRT2 server.  

Hardware Setup

This describes the hardware configuration processes that must be followed when installing or uninstalling system components. 

 AOM-PTG-I2T-P (Riser card) Installation

                   

                                   
  1. Power down the system and open the chassis cover.
    1. Remove the Add on cards and find the Slot A1 in the Motherboard. Slot A1 is the slot for AOM-PTG-I2T-P riser card in the server As-4125GS-TNRT2.
    2. Insert the Riser card into the slot A1
    3. After Installation we can find the details of the riser card in Baseband management console
       
       Fig.1 shows the Riser card slot (Slot A1) in the Motherboard H13DSG-O-CPU

Installation Procedure
  1. Shut down the server and remove power cords
  2. Remove the chassis cover. Do not power on server without its cover because of airflow reasons.
  3. Locate and prepare the PCIe Expansion slot in MB (Fig.1)
  4. Install the Expansion card-  Align the card's connector with the PCIe slot, Gently insert the card into the slot until fully seated
  5. Secure the card with screws
  6. Connect Auxiliary power - For GPUs and other high power cords.
  7. Reinstall the chassis cover.
  8. Power Up the server to check the PCIe Expansion Card is recognized and performs as expected
