Install the front I/O board

Use this information to install the front I/O board.

Procedure

1. Install the front I/O board to the system board assembly.
   Figure 1. Installing the front I/O board
   
   
2. There is a Mylar sheet between the front I/O board and the supporting metal sheet.
   Figure 2. Side view of front I/O board portion of the system-board assembly
   
   

   1 Front I/O board

   2 Mylar sheet

   3 Supporting sheet metal

   1. Insert the tip of the DIMM tool between the front I/O board and the Mylar sheet. Then, use the tip to press down the Mylar sheet to prevent the dip pins on the bottom of the FIO board sticking to the Mylar sheet.

3. Install two M3 PH1 screws to secure the front I/O board to the system board assembly.

4. Install the FPC cable to the front I/O board and the system I/O board.
   1. Pull up the latch of the connectors on the front I/O board and the system I/O board.

   3. There is a white line on both ends of the FPC cable. Insert the FPC cable to the connectors until the white lines are invisible. The FPC cable is not installed correctly if the white lines are visible.
      Figure 7. Checking proper FPC cable installation
      
      

      If the white line is still visible after inserting the FPC cable, check if the connector latches are fully pulled up and loosen.

7. Install the system-board assembly to the tray.
   Note

   Hold the system-board assembly by the thumbscrew in the front and the tab beside the power connector.

9. Install the PDB tray.
   1. Align the power connectors on PDB tray to the power connectors to the system boards.
   2. There are triangle markings on the inside of the right-side and left-side of the tray. Push the PDB tray into the server tray. Stop pushing when the PDB tray meets the triangle markings.
   3. Rotate both PDB tray handles at the same time to the lock position
   Attention

   Make sure to rotate both handles at the same time.
