OCATIONS
Each power supply backplane supports two power supplies. Each backplane has one, eight-position,
slide-style switch consisting of eight, single-pole single-throw (SPST) switches numbered 1 through 8.
Figure 10 depicts the location of these switches with the power supplies removed and the corresponding
dipswitch settings.
These dipswitches are preset at the factory. Do not change the settings!
