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

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

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 node.

Figure 1. Connectors on the rear of the 2145-CG8 node

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

1. If present, remove both Ethernet small form-factor pluggable (SFP) transceivers before replacing the Ethernet riser-card assembly, as described in Removing and replacing an Ethernet SFP transceiver.
2. Grasp each end of the Ethernet riser-card assembly, tilt the Ethernet riser-card assembly so that the side with the PCI riser card is higher than the opposite side, and the back is higher than the front.
3. Locate the cage that houses the Ethernet SFP transceivers through the hole in the back of the node.
4. Align the 10 Gbps Ethernet riser-card assembly connector with the PCI slot 2 connector on the system board, as shown in Figure 2.

   •  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.

5. Press down on the top of the Ethernet riser-card assembly until the card settles in the slot.
6. Anchor the Ethernet riser-card assembly using two fastening screws from the back of the node, as shown in the cutaway view of a section of the rail in Figure 3.

   •  1  10 Gbps Ethernet port 1
   •  2  10 Gbps Ethernet port 2
   •  3  Back-rail retaining screws
7. Install both SFP transceivers into the Ethernet riser-card assembly, as described in Removing and replacing an Ethernet SFP transceiver.
8. If you did not do so as part of the procedure for replacing the Ethernet SFP transceivers, 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.
9. If you did not do so as part of the procedure for replacing the Ethernet SFP transceivers, replace the top cover, following the procedure in Replacing the top cover and being careful to reattach the fiber optic cable to Ethernet port 1 before replacing the serial cable connecting the node to the UPS.

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