Removing the SAN Volume Controller 2145-CF8 fibre-channel adapter assembly

To remove the SAN Volume Controller 2145-CF8 fibre-channel adapter assembly, perform the following steps:

DANGER

Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords.

Figure 1. Connectors on the rear of the SAN Volume Controller 2145-CF8

•  1  Fibre-channel port 1
•  2  Fibre-channel port 2
•  3  Fibre-channel port 3
•  4  Fibre-channel port 4
•  5  Power connector 1
•  6  Power connector 2
•  7  Serial port for UPS communications (RS232)
•  8  Ethernet port 2
•  9  Ethernet port 1

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.
   
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.
   

   You can perform most service actions when the node is fully extended from the rack on its slide rails. 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.

7. Remove the top cover. See Removing the top cover.
   
8. Remove all SFPs before removing the adapter, as described in Removing and replacing the fibre-channel SFP connector on a SAN Volume Controller node.
9. Remove the two M3 screws that attach the adapter assembly to the back rail.

   The fibre-channel adapter assembly and the high-speed SAS adapter assembly each attach to the back rail with two screws, as shown in the partial view of the rail with the fibre-channel adapter assembly attached in Figure 2.

   •  1  Fibre-channel ports 1 - 4
   •  2  Back-rail retaining screws
10. After removing the back-rail retaining screws for the adapter assembly, grasp the riser-card assembly at either end and pull up out of the slot 1 riser-card connector, as shown in Figure 3. Once the riser card clears the connector, gently twist the card assembly to separate the assembly from the node.
    Figure 3. Removing the fibre-channel riser-card assembly for the SAN Volume Controller 2145-CF8

    When looking from the back, the slot 1 connector is the connector on the left. The high-speed SAS riser-card assembly, if present, attaches to the slot 2 connector on the left side of the system board, when looking from the back. If there is no high-speed SAS adapter riser-card assembly, a riser-card adapter is present in slot 2.

11. Place the riser-card assembly on a flat, static-protective surface.
12. If you are instructed to return the fibre-channel adapter assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
