5.3.5 Power Supply Numbering
InServ F-Class Storage Server cabinets share a single power domain that contains a drive cage
or controller node and two dedicated power supplies. Drive cages and controller nodes
depend on these two power supplies to supply power from the PDUs at the bottom of the
cabinet. When viewing the cabinet from the rear, the power supplies are numbered as follows
(Figure 5-14):
4 7 9, 13

unpredictable results.
