Cable Test Results - Wire Map
When the link is down:
Short: Short-circuit between Tip and Ring wires of a pair or Tip or
ring wire of a pair is connected with an alien wire grounded.
Open: No cable plugged in, remote end open, or either one or two
wires of a pair are not connected.
Short-between-pairs: Short between one or two wires of a pair
with one or two wires of another pair. Short between more than
two pairs, including one or two wires for each pair.
Noise: Excessive noise on a pair most likely caused by a link
partner running in 10/100Mbps forced mode. In this case, no
distance is reported and there is no comparison with any
threshold.
Unknown: No fault has been identified but the link is down. To
maximize the cable test result, it is preferable to have the far end
equipment powered up.
Note: Refer to Ethernet Cables on page 286 for cable pinout.
