1.) Unswitched Convenience Outlets: These outlets provide power always, even when the GNL-3300E is switched off. These outlets provide filtered power.

2.) 10A Circuit Breaker : The GNL-3300E's current rating is 10A (max), when the current is over 10A, the breaker will trip to cut off the power.

3.) Power : The power switch. When it's switched to "on" the GNL-3300E will provide the 4 pairs of outlets in 1 turns, the sequence will be reversed when it's switched to "off".

4.) Zone 1 / Zone 2 / Zone 3 LED : The indicators will light when the Zone 1, Zone 2, or Zone 3 (Digital/ Analog/High Power) are connected to your components.

5.) Breaker Open LED : The LED will light when the circuit breaker has tripped due to overload to protect your equipment.

6.) Wiring fault LED: This LED indicates if the Line and Neutral wires inside the wall outlet are reversed. Unplug the appliance immediately and consult your electrician company when the LED is on.

7.) Abnormal Voltage LED : The LED will light when the supply voltage is not normal (over 260 VAC or under 170 VAC)

8.) Voltage Meter : The LED shows numeric which indicates the AC voltage the unit is receiving from the wall. LED light is super-bright,retractable,long life and low-heat can provide illumination for rack installations.

9.) LED light switch : This HIGH/LOW/OFF SWITCH is used to switch on or off the LED light and adjust the illumination of LED light.

Rear Panel Features:

1.) Digital / Analog / High Power Outlets :

• These outlets have three kinds of filter (Digital filter / Analog Filter / High Power Filter) which are designed  to reduce the noise to your digital/analog/high current componenets.
• The digital component is such as CD player, or computer.
• The Analog component such as mixer.
• The High power component is such as power amplifier.

2.) Chassis Ground : It is used to connect the chassis of GNL-3300e to ground to avoid possible electric shock.
