Chapter
There is a safety interlock between the front of the server cover and the
Power Supply. When the cover is taken off, power is automatically removed
from the server if power cords were not detached previously.
DO NOT attempt to defeat this interlock. Doing so will expose you to high
levels of electrical amperage that can cause serious injury or death.
