Connecting cables to the processor and memory expansion tray

When working on cable routing plans that involve the processor and memory expansion tray, perform the procedure in the following order.

1. Connect the following:

   • Connect all the cables in the plan to corresponding drive backplanes.
   • Connect all the SAS/SATA cables to the adapters or the on-board SAS/SATA connector.
   • If applicable, connect the two PCIe cables to the connectors on the system board.
2. Install the expansion tray air baffle.

   • Rotate the handle all the way down. This connects and fixes the expansion tray to the system board.
   • Pull the retaining tab back to secure the handle.
