If you have more Expansion chassis than those illustrated, continue the indicated cabling pattern,
alternating connections for additional Expansion chassis between DP1 and DP0. Expansion chassis
1, 3, 5, 7, etc. (odd numbers) connect to DP1. Expansion chassis 2, 4, 6, 8, etc. (even numbers)
connect to DP0. For example, if you have four Expansion chassis (an even number), they are evenly
balanced, so you have two connected to DP1 and two connected to DP0. If you have five Expansion
chassis (an odd number), the “plus one” Expansion chassis is always connected to DP1, so you have
three connected to DP1 and two connected to DP0.
