1. Read the safety information to which Preparing to remove and replace parts refers.
2. Attach the high-speed SAS cable to the connector on the bottom of the high-speed SAS adapter, as described in Replacing the high-speed SAS cable: 2145-CG8 or 2145-CF8.

   Attach the cable so that the end with the label is to the front of the node and the end without the label attaches to the adapter.

3. Insert the adapter into the riser card, then insert the assembly into the slot 2 connector on the system board.

   As you start inserting the adapter, align the edge connector on the low-profile adapter with the connector on the riser-card assembly. Make sure that the adapter snaps into the riser-card securely.

   Then press the riser-card edge connector  2  firmly into the system-board slot 2 connector  1 , as shown in Figure 1.

   When viewed from the back of the node, the slot 1 connector is on the left and contains the Fibre Channel adapter assembly. The slot 2 connector is on the right when viewed from the back of the node.

4. Grasp the high-speed SAS adapter assembly to steady it while you align and attach the adapter assembly to the back rail with the two M3 screws that were removed during the removal of the adapter.

   The high-speed SAS adapter assembly and the Fibre Channel adapter assembly each attach to the back rail with two screws ( 1 ), as shown in the view of the rail with the high-speed SAS adapter assembly attached in Figure 2.

5. Make sure that all cables, adapters, and other components are installed and seated correctly and that you have not left loose tools or parts inside the node. Make sure that all internal cables are correctly routed. If you disconnected the Fibre Channel and Ethernet cables, make sure that each cable is reconnected to the same port from which it was removed.
6. Replace the top cover. See Replacing the top cover.

   After following the procedure to replace the top cover, the node is installed in the rack and is turned on.
