b.Connect one end of an SMP Expansion cable to port 2 on node 2; then, route the cable through the node 2 cable-management arm. Use a 2.3-m (7.6-foot) SMP Expansion cable for this connection.

c.Locate the SMP Expansion cable that is connected to port 3 on node 1; then, connect the opposite end of the cable to port 3 of node 2. Next, route the cable through the node 2 cable-management arm.

5.Connect the SMP Expansion cables to node 3:

a.Locate the SMP Expansion cable that is connected to port 1 on node 2; then, connect the opposite end of the cable to port 1 of node 3. Next, route the cable through the node 3 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 3. Next, route the cable through the node 3 cable-management arm.

c.Connect one end of an SMP Expansion cable to port 3 on node 3; then, route the cable through the node 3 cable-management arm. Use a 2.3-m (7.6-foot) SMP Expansion cable for this connection.

6.Connect the SMP Expansion cables to node 4:

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 4. Next, route the cable through the node 4 cable-management arm.

b.Locate the SMP Expansion cable that is connected to port 2 on node 2; then, connect the opposite end of the cable to port 2 of node 4. Next, route the cable through the node 4 cable-management arm.

c.Locate the SMP Expansion cable that is connected to port 3 on node 3; then, connect the opposite end of the cable to port 3 of node 4. Next, route the cable through the node 4 cable-management arm.

7.Route any remaining cables through the cable-management arms.

8.Secure the cables in the cable-management arms with the hook-and-loop straps that come with the server.

Eight-node configuration

An eight-node configuration requires four 2.9-m (9.5-foot) XpandOnDemand Scalability cable kits and eight 2.3-m (7.6-foot) XpandOnDemand Scalability cable kits. To cable an eight-node configuration for up to 32-way operation, complete the following steps:

1. Remove the protective covers from the connectors on the ends of the cables.
