Power Status Check

Use the PWR LED indicator on NPort Express’s top panel to see if it is receiving power. A red light indicates that power is being received. The absence of a light indicates that power is not being received. If the unit is plugged in, or is receiving power over cable, then an unlit PWR LED indicator shows that something is wrong with the NPort Express unit’s operation.
