Node 1 Node 2 3. Connect the SMP Expansion cables to node 1: a. Connect one end of an SMP Expansion cable to port 1 on node 1; then, route the cable through the node 1 cable-management arm. Use a 2.3-m (7.6-foot) SMP Expansion cable for this connection. b. Connect one end of an SMP Expansion cable to port 2 on node 1; then, route the cable through the node 1 cable-management arm. Use a 2.3-m (7.6-foot) SMP Expansion cable for this connection. 4. Connect the SMP Expansion cables to node 2: a. Locate the SMP Expansion cable that is connected to port 1 on node 1; then, connect the opposite end of the cable to port 1 of node 2. Next, route the cable through the node 2 cable-management arm. b. Locate the SMP Expansion cable that is connected to port 2 on node 1; then, connect the opposite end of the cable to port 2 of node 2. Next, route the cable through the node 2 cable-management arm. 5. Route any remaining cables through the cable-management arms. 6. Secure the cables in the cable-management arms with the hook-and-loop straps that come with the server. 7. Configure the scalable partition. See "Using the Scalable Partition Web Interface" on page 51. Four-node configuration A four-node configuration requires six 2.3-m (7.6-foot) XpandOnDemand Scalability cable kits. To cable a four-node configuration for up to 16-way operation, complete the following steps: 1. Remove the protective covers from the connectors on the ends of the cables. Protective cover 2. Label each end of the SMP Expansion cables according to where it will be connected to each server. See the following illustration. 24 IBM System x3950 Type 8872 and System x3950 E Type 8874: Installation Guide
