Indicator

Definition

Normal level, normal polarity

Normal level, reverse polarity

Low level, normal polarity

Low level, reverse polarity. Link level is displayed by the height of the waveform.

Under the NetTool icon, you can also obtain status information for the cables connected to NetTool. For example:

ahn235f.eps

The tester detects whether the cables are straight or swapped. If it sees a swap cable problem, it swaps the cables internally, allowing you to troubleshoot past a simple swap cable problem.

The LEDs on either side of NetTool indicate the status and utilization of the link and whether NetTool discovers any errors.
