Understanding the LEDs

On each side of the LCD, NetTool has a pair of LED

indicators (Figure 1-3). These LEDs combine to give you

immediate insight and at-a-glance information about your

network environment. The top pair of LEDs provides link,

collision, and error information while the bottom pair

indicates utilization levels.
