Configuring the Power Relay Board
Since all of BLACK BOX's intelligent sensors are configured similarly
not every field is described below. The descriptions below describe the
fields that are special to the Power Relay Board.
For a general description about configuring all sensors including
information regarding common configuration parameters please see the
Installing and Configuring Sensors page.
Status: If the sensor is offline the status is “noStatus” . If the relay is
ON, then the status is “normal” , and if the relay is in OFF position,
then the status is “critical” . If at any time communications with the
Power Relay Board is lost, the status is changed to “sensorError” .
