Install the PCIe expansion cage

Use this information to install the PCIe expansion cage.

To install the PCIe expansion cage, complete the following steps:

1. Orient the PCIe expansion cage so that the PCIe expansion cage cover is at the top.
2. Install GPU adapters, if necessary.

   • See Remove a FHFL GPU adapter.

   • See Remove a FHHL GPU adapter.

3. Install the PCIe expansion cage cover and cable management tray, if necessary.
   1. Push the USB and VGA cables into the cage to create sufficient slack in the cables; then, position the front of the cable management tray into the PCIe expansion cage and lower the rear of the cable management tray.
      Note

      Optionally, a USB port assembly and a video port can be installed in the cable management tray of PCIe expansion cage 1. If they are installed, you must remove the drive cage assembly to connect the video port cable 1 and the USB cable 2 to the system board. See Remove the drive cage.

   2. Lower the expansion cage cover onto the PCIe expansion cage and slide it into place.
      Figure 2. Installing the PCIe expansion cage cover and cable management tray.

      The 3-slot expansion cage is shown in this figure. The process for installing the 4-slot expansion cage is the same.

      
      
      
4. Connect the power cable to the system board. If you are installing PCIe expansion cage 1, make sure that the USB and video cables are connect to the system board as well.

6. Align the nailheads on the expansion cage with the slots in the server chassis; then, lower the PCIe expansion cage into the server chassis.
7. Slide the expansion cage toward the front of the server until it clicks into place.

   The 3-slot expansion cage is shown in this figure. The process for installing the 4-slot expansion cage is the same.

   
   
   
8. Connect the PCIe cables from the PCIe expansion cage to the system board.
9. Route the power cables through the guides and gaps located under the fan cage.

     Note

     If you are installing PCIe expansion cage 1, remember to route the USB and VGA cables. See Video and USB cable routing.
