LED Indicator Westell Technologies automatic safety precautions are built into the amplifier system. In the case of a catastrophic system event, a shutdown circuit is incorporated that will disable all emissions should the uplink input or downlink input be over driven or should an oscillation or output overpower event occur. The amplifier will periodically attempt to recover from the detected condition automatically.
