Alert LED: This LED output indicates that greater than 80% traffic level for
one second or more has occurred, or a 10BASE-T port partition has occurred.
The output remains active until the current event condition ceases or, if the
event condition is shorter than 30ms, for a minimum of 30ms (nominal value).
Active low.
