Powering Down the System

During installation you may need to power down the system for
troubleshooting or adding new equipment to the carrier.
CAUTION:
Follow these steps in the exact sequence.
1. Turn off the power supply on the basic carrier.
2. Turn off the power supplies on the expansion carriers.
3. Unplug any auxiliary power units.
Because the power supplies are already off, the sequence for
removing auxiliary power cords is not important.
4. Unplug the system from the AC outlet.
