Check the circuit breaker. Ideally, the NBX
100 should be on its own breaker-
protected circuit. Each chassis can draw up
to 4 amps.

NBX 100 (cont.)
Electrical outlet
If the circuit breaker is not tripped, make
sure that there is power present at the
outlet. Check that the outlet is not
controlled by a wall switch.

If the outlet faceplate shows
any blackening or discoloration it could
indicate a short. Call an electrician.
