Removing the 10 Gbps Ethernet riser-card assembly: 2145-CG8

An authorized IBM service provider can remove the 10 gigabits per second (Gbps) Ethernet riser-card assembly from the SAN Volume Controller 2145-CG8 node.

Figure 1 shows the connectors on the rear of the SAN Volume Controller 2145-CG8:

Figure 1. Connectors on the rear of the SAN Volume Controller 2145-CG8

•  1  Fibre Channel port 1
•  2  Fibre Channel port 2
•  3  Fibre Channel port 3
•  4  Fibre Channel port 4
•  5  Ethernet port 3 (10 Gbps)
•  6  Ethernet port 4 (10 Gbps)
•  7  Power connector 1
•  8  Power connector 2
•  9  Serial port for Uninterruptible power-supply communications (RS232)
•  10  Ethernet port 1 (1 Gbps)
•  11  Ethernet port 2 (1 Gbps)

1. Read the safety information to which Preparing to remove and replace parts refers.
2. Perform the procedure to remove the top cover, performing the optional steps to turn off the node and remove the node from the rack, if it is easier to work on the node that way, as described in Removing the top cover.

   As you label and remove all cables after turning off the node in the Removing the top cover procedure, be sure to remove the serial cable from the UPS that attaches to the serial port on the back of the node before you attempt to remove the fiber optic cable and the Ethernet small form-factor pluggable (SFP) transceiver from the first port on the Ethernet card in the 10 Gbps Ethernet riser-card assembly.

   Remove the two fiber optic cables from the 10 Gbps Ethernet riser-card assembly by pressing their release tabs and pulling each cable out. Be careful to exert pressure only on the connectors and do not pull on the fiber optic cables.

3. Remove both Ethernet SFP transceivers, as described in Removing and replacing an Ethernet SFP transceiver before removing the Ethernet riser-card assembly.
4. Remove the two M3 screws that attach the Ethernet riser-card assembly to the back rail.

   The 10 Gbps Ethernet riser-card assembly attaches to the back rail with two screws, as shown in the partial view of the rail with the 10 Gbps Ethernet riser-card assembly attached in Figure 2.

   •  1  10 Gbps Ethernet port 1
   •  2  10 Gbps Ethernet port 2
   •  3  Back-rail retaining screws
5. After removing the back-rail retaining screws for the Ethernet riser-card assembly, grasp the Ethernet riser-card assembly at either end and pull up out of the PCI slot 2 riser-card connector, as shown in Figure 3. Once the Ethernet riser-card assembly clears the connector, gently twist the Ethernet riser-card assembly to separate the Ethernet riser-card assembly from the node.
   Figure 3. Removing the 10 Gbps Ethernet riser-card assembly

   
   •  1  PCI slot 2 riser-card connector
   •  2  10 Gbps Ethernet riser-card assembly

   When looking from the back, the PCI slot 1 connector is the connector on the left. The 10 Gbps Ethernet riser-card assembly attaches to the PCI slot 2 connector on the right side of the system board, when looking from the back.

   Note: Do not power on the node with nothing connected to the system planar PCI slot 2. If you are replacing the Ethernet adapter, insert the replacement adapter. If you are not replacing the Ethernet adapter, either insert a high speed SAS adapter (feature code 4500), or a riser card. If you need a riser card and do not have one, you can remove the riser card from the 10 Gbps Ethernet card that you just removed.
6. Place the Ethernet riser-card assembly on a flat, static-protective surface.
7. If you are instructed to return the 10 Gbps Ethernet riser-card assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
