GE ports have four pairs of cable that will be diagnosed. Link Up  When a port is in link-up status the test will be able to determine the distance of the cable as well as any problems it may have. Due to the fact the port is in link-up status it will not have any Short or Open problems, but the test may still detect if there is a Crosstalk problem. Link Down  When a particular port is in link-down status, the link-down may be caused by many factors;  When the port has a normal cable connection, but the remote partner is powered off, the cable diagnosis can still diagnose the health of the cable as if the remote partner was powered on.  When the port does not have any cable connection, the result of the test will indicate no cable.  The test will detect the type of error and the position where the error has occurred. 42
