Replacing a PCI express riser-card assembly: 2145-SV1

Use these instructions when you are prompted to replace a PCI express riser card assembly on a SAN Volume Controller 2145-SV1 node.

For the list of the expansion adapters that are supported by each PCIe slot, see Optional features. Install any new PCIe expansion cards by gently pushing them into the correct PCIe slot.

1. Reinstall any adapters that were removed in the same slot.
2. Align the PCI riser-card assembly with the selected PCI connector on the system board, as shown in Figure 1.

   The chassis might sag after you remove the riser assembly. In this case, lift the bottom of the chassis to line up the slots on the side of the assembly to the alignment brackets in the side of the chassis.

   1. For PCI connector 1, carefully fit the two alignment slots on the side of the assembly onto the two alignment brackets in the side of the chassis.
   2. For PCI connector 2, carefully align the bottom edge (the contact edge) of the riser-card with the riser-card connector on the system board.
   3. For PCI connector 3, carefully align the bottom edge (the contact edge) of the riser-card with the riser-card connector on the system board.
3. Press down on the assembly and make sure that each riser-card assembly is fully seated in the riser-card connector on the system board, as Figure 2 shows.

4. Repeat steps Figure 1 and 3 to replace addition PCI riser-assemblies, as needed.
5. Replace the top back cover, as described in Replacing the top covers: 2145-SV1.
6. Slide the 2145-SV1 node into the rack, as described in Replacing a node in a rack: 2145-SV1.
7. Reconnect all signal cables to the same ports from which they were removed.
