Installation Notes:
 If you intend to expand your system, you may want to leave enough space
to install additional expansion chassis and switches at a later date. Expansion
chassis and switches are ordered separately. Expansion chassis and switches
can be racked in any order, but the preferred locations are shown in Figure 8.
Expansion PDUs should be installed above the base PDUs.
