Removing the SAN Volume Controller 2145-CF8 high-speed SAS adapter assembly

You can remove the SAN Volume Controller 2145-CF8 high-speed SAS adapter assembly.

1. Read the safety information to which Preparing to remove and replace parts refers.
2. Follow the procedure in MAP 5350: Powering off a SAN Volume Controller node to verify that the node data is mirrored and synchronized, and that there are no dependent virtual disks (VDisks) before turning off the node.
   
3. Slide the node out on its slide rails to the fully extended position.
   

   You can perform most service actions when the node is fully extended from the rack on its slide rails. You can leave the fibre-channel and Ethernet cables connected, if you are using the cable-management arm and if you are not removing the node from the rack. If the location of the node in the rack is too high or too low to work comfortably, you can remove the node from the rack.

4. When the node is completely turned off, remove the cable-retention brackets and disconnect the power cables, as described in Removing the cable-retention bracket.
   
5. To make sure that you can replace all cables in the same ports from which they were removed, label the port position of each fibre-channel and Ethernet cable; then remove all cables from the back of the node.
   
6. Optional: Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
   
7. Remove the top cover. See Removing the top cover.
   
8. Remove the two M3 screws that attach the adapter assembly to the back rail.

   The high-speed SAS adapter assembly and the fibre-channel adapter assembly each attach to the back rail with two screws, as shown in the partial view of the rail with the high-speed SAS adapter assembly attached in Figure 1.

10. Grasp the high-speed SAS adapter riser-card assembly by its top edge or upper corners and pull the card up out of the slot 2 riser-card connector.

    When looking from the back, the slot 2 connector is the connector on the right. The 4-port fibre-channel adapter attaches to the slot 1 connector on the left side of the system board, when looking from the back.

11. Remove the high-speed SAS adapter cable from the adapter.
12. Place the high-speed SAS adapter riser-card assembly on a flat, static-protective surface.
13. If you are instructed to return the high-speed SAS adapter riser-card assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
