Circuit Breaker Reset Switch
The circuit breaker contains an external button to indicate power fault status. When the button is
extended (white area showing), a fault has occurred. Do not reset the circuit breaker until after the fault
has been removed. Reset the circuit breaker by pressing the button.
Safety Interlock Switch
The safety interlock switch, located in the top of the base unit, prevents the system from powering on if
the top cover is not properly installed.
Power Cables
These two-wire cables provide the AC line and neutral signals to the power distribution board, which in
turn drives the power supplies.
Power Supply Cable Opening
The main power cable from the power distribution board to the riser card passes through this opening.
If servicing the AC section, be sure the plastic edging remains in the opening to protect the wires from
damage.
