Chapter 6: Operation
Time to test: Short cables take longer to test because fewer
measurements per pass are possible. The thousands of
measurements required are accomplished much faster on longer
cables than shorter cables.
Figure 6-11. Testing is halted
until the Remote Probe is connected.
The Remote Probe is required for the wire map to be
constructed. Plug the Remote Probe into the far end of the
cable. Tracer tones have been turned ON to help locate cables in
crowded areas (press the TRACE button on the Remote Probe
and hold it close to the cable to follow the tone). The Main
Unit’s wire map test is triggered when the Remote Probe is
connected to the far end of the cable (there are no buttons to
push). The wire map tests for correct cable pairing.
NOTE: The wire map is displayed during the Review process, not
during the test.
Remote Probe LEDs. The Remote Probe needs to be connected
only for a brief period. Flashing LED(s) indicate the test is pro-
gressing. A steady LED indicates the test is completed. This saves
you an extra trip to retrieve the probe. If LED(s) continue to flash
the cable, the cable has a wiring problem. Disconnect the probe
and go to the Main Unit to see the results.
NOTE: If you plan to test to LAN Performance Verification Level
2, now is a good time to plug in the hub, switch, or PC (it
will save you a trip).
