4.6.1 Two-node configuration
A two-node configuration requires two 3.0 m (9.8 feet) ScaleXpander cables. The
cable diagram is shown in Figure 4-13 on page 213. One 3.0 m cable is included
with every x3950 M2 system, or in the ScaleXpander Option Kit (for the upgraded
x3850 M2 systems).
The scalability cables required for a two-node configuration are listed in
Table 4-4.

To cable a two-node configuration:
1. Label each end of each ScaleXpander cable according to where it will be
connected to each server.
2. Connect the ScaleXpander cables to node1:
a. Connect one end of a ScaleXpander cable to port 1 on node 1; then,
connect the opposite end of the cable to port 1 of node 2.
b. Connect one end of a ScaleXpander cable to port 2 on node 2; then,
connect the opposite end of the cable to port 2 of node 2.
See Figure 4-13 on page 213.
