A cubicle is a kit of panels, worksurfaces, and connectors that only goes back together one way. The whole job lives or dies on labeling, so document before you touch a single panel.
Pro tip: Number panels with painter's tape in the order you remove them, then reinstall in exact reverse order for a foolproof rebuild.
Watch out: Do not attempt to disconnect powered base rails yourself; hardwired raceways should be handled by a qualified electrician.
