    What are the basic troubleshooting steps for the G-Type Rack Power Filter; G5BLK?


    What are the basic troubleshooting steps for the G5BLK?

    Product Line:

    APC G-Type Rack Power Filter




    During normal operation, you may find your G5BLK not functioning as expected. This may be due to a malfunction, configuration issue, or the install environment.
    This document will assist you with basic troubleshooting steps.

    Problem and Possible Cause Solution
    The unit will not turn on  
    There is no input power, or insufficient input power from the wall outlet. Use a voltmeter to check the output of the wall outlet. Use a device that is known to work properly to check the outlet.

    Note: The unit will not turn on if the input utility power is out of the acceptable range.
    A circuit breaker has been tripped. Check the building circuit breakers and the unit’s circuit breaker. If the circuit breaker on the unit has been tripped, the center post will protrude from the unit. To reset the breaker, push the center post into the unit. If it trips again, unplug one of the components plugged into the unit and reset the breaker.

    The unit is rated for 15 Amps, however, the National Electric Code (NEC) dictates that any home circuit should not be loaded to more than 80% of its rating.

    Note: If the breaker is tripped again after trying this solution, contact APC Technical Support.
    The Overload indicator is illuminated
    The unit is overloaded. The overload LED is flashing. The Overload LED on the front of the unit will illuminate red if the unit is overloaded. Reduce the load by disconnecting one or more components from the back of the unit. When the load is below 95%, the LED will stop flashing.
    The Wiring OK indicator is not illuminated
    • The wall outlet polarity is reversed.
    • The neutral wire is overloaded.
    • The earth ground is not connected at the wall outlet.
    Contact an electrician to inspect the building wiring.

    WARNING: Do not operate the unit if any of these conditions exist. The unit may not be providing surge protection.
    The unit is on, but none of the LEDs are illuminated. Push UP or DOWN several times.

    The LEDs should illuminate.

    If they do not illuminate, contact APC Technical Support.
