Removing the Fibre Channel adapter assembly: 2145-CG8 or 2145-CF8

To remove the SAN Volume Controller 2145-CG8 or 2145-CF8 Fibre Channel adapter assembly, complete the following steps:

Before you begin

DANGER

Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords. (L003)

Figure 1 shows the connectors on the rear of the SAN Volume Controller 2145-CG8 or 2145-CF8 node.

Figure 1. Connectors on the rear of the SAN Volume Controller 2145-CG8 or 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 Uninterruptible power supply communications (RS232)
•  8  Ethernet port 1 (1 Gbps)
•  9  Ethernet port 2 (1 Gbps)

Note: On a 2145-CG8 node, a second Fibre Channel adapter may be installed. Verify which Fibre Channel adapter you are removing. The correct adapter will be indicated in the directed maintenance procedure you are following.

1. Read the safety information to which Preparing to remove and replace parts refers.
2. Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power 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 a node from a rack.

   You can accomplish 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, as described in Removing the top cover: 2145-CG8 or 2145-CF8.
8. Identify the Fibre Channel adapter you are removing. When looking at the rear of the node, adapter 1 (required) is on the left; adapter 2 (optional) is on the right.
9. Remove all small form-factor pluggable (SFP) transceivers before removing the adapter, as described in Removing and replacing a Fibre Channel SFP transceiver.
10. 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. You can see a partial view of the rail with the Fibre Channel adapter assembly attached in Figure 2.

    Figure 2. The SAN Volume Controller 2145-CG8 or 2145-CF8 Fibre Channel adapter 1

    
    •  1  Fibre Channel ports 1 - 4
    •  2  Back-rail retaining screws
11. After removing the back-rail retaining screws for the adapter assembly, grasp the riser-card assembly at either end and pull up and 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.

    Remove the identified Fibre Channel riser card assembly.

12. Place the riser-card assembly on a flat, static-protective surface.
13. If you are instructed to return the Fibre Channel adapter assembly, follow all packaging instructions. Use any packaging materials for shipping that are supplied to you.
