Chapter 6 Interpreting Test Results

Interpreting Cable Test Results

70 LanScaperPRO Network Tester User’s Guide

Rtr must be on MyIP LAN segment

Displayed in Setup while setting the Manual Router IP

address. The LanScaperPRO requires that the Router be

at an IP address on the LAN segment as defined by the

Netmask and MyIP addresses. Setup will not allow the

Router IP address to be set to an off-LAN address.

Voltage Found, Press Test to Run PoE Test

The tester will not run tests when voltage and possibly

destructive power is found. Voltages are checked for at

the beginning of each test, and if found will terminate the

test in progress. The only option is to run the PoE test (by

pressing TEST.)

Interpreting Cable Test Results

The PASS message will be displayed if the cable has all

pins properly connected per T568A/B. The FAIL

message will be displayed if there is any fault. This

requires that a remote be attached to the far end of the

cable to allow the wiremap to be verified.

Definition of

Errors

The classes of faults discussed on the following pages are

listed in order of severity. Note that more severe errors

can mask lower severity errors. For example, if there is a

short in the cable, miswires and splits pairs may not be

detected for the pairs involved in the short fault. So, if a

higher severity error is displayed, there may be others of

lower severity that are not displayed. Given this, it is a

good idea to retest cables after repairing faults.
