HP BL20p - ProLiant - G2 Setup And Installation Manual page 96

The zone 1 switch setting is the default position; it is used for scalable bus bar, single
mini bus bar, and power bus box solutions. The zone 2 switch setting is only used for
a secondary power zone when you configure a full-rack 42U solution with two pairs
of mini bus bars.
For the system to recognize multiple power zones and rack topology properly, you
must set these switches at the time of installation. Use Figure D-9 and Table D-9 to
identify switch locations and settings.
