Install the system I/O board (DC-SCM)

Use this information to install the system I/O board. System I/O board is also known as Datacenter-ready Secure Control Module (DC-SCM).

Procedure

1. Install the system I/O board.
   1. Install the system I/O board to the system board assembly.
   2. Install two M3 PH1 screws to secure the system I/O board to the system board assembly.
   Figure 1. Installing the system I/O board
   
   
2. 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.

5. 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.

7. 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.
