If voltage is not present on the power supply side of the circuit
breaker and the circuit breaker is not tripped, the breaker is
damaged. If the circuit breaker is damaged, it is recommended that
the R450 DC be returned for repair.

computer.
1. Put on your wrist strap and attach the alligator clip to the cabinet.
2. Turn off the circuit breaker.
3. Remove the 10-pin connector located in the upper left corner of
the CPU Board. There is a locking tab on the bottom side of the
connector.
