Power Supply Numbering
The cabinets are divided into upper and lower power domains containing drive cages or controller
nodes and dedicated power supplies. The drive cages and controller nodes depend on these
power supplies connecting to PDUs for power.
When viewing the cabinet from the rear, the power supplies in drive chassis in each power domain
are numbered from 0 to 3, from left to right (Figure 29 (page 40)). Each node contains two power
supplies that are numbered 0 and 1, from left to right.
