Applying Power

Initial power application is a matter of turning on the ac input boxes
located in the lower left and right corners of the enclosure (see Figure

power only to the shelf power supplies on the associated power bus
(bus A or B).
Apply power in the following sequence:
1. All expansion enclosures
