Re-label all inter-rack cables from leaf switches to spine switches. Re-label each cable to identify the correct locations at both cable ends, so that cables can be connected correctly during future maintenance. Label all cables using the following convention:
Rack[#]LeafSW[#]Port[#] -> Rack[#]SpineSW[#]Port[#]
When labeling racks, label all installed Exalogic machines (or a combination of Exalogic machine and Exadata Database Machine) according to the plan you prepared in the previous chapter.
