a certain level of network utilization is exceeded for
five seconds. The levels are:
■
High
— 80% network utilization
■
Med
— 50% network utilization
■
Low
— 12% network utilization
If this condition is resolved after causing the Alert
LED to light, the LED goes off (it stays lit if other
conditions also caused it to light).
Following a period of excessive network activity, the
Alert LED stays lit for a short period of time.
