Summary (Cable Test)
When the link is down:
If the determined
Wire Map
is either
MDI
,
MDIX
,
MDI (-)
,
MDIX (-)
, or
Noise
(Link up), the test is declared as
PASS
. If the determined Wire
Map is either
Short
,
Short-between-pair
,
Open
,
Noise
(Link down), or
Unknown
, the test is declared as FAIL.
Note:
Refer to
on page 606 for cable pinout.
Distance To Fault (m/ft)
gives the distance to fault from the near end
for each pair, unless the problem is due to excessive noise. Noise may
be due to electrical noise causing communication error.
Prop. Delay (ns)
indicates the propagation delay of a signal through
each pair.
Length (m/ft)
indicates the cable length of each pair.
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 10/100 Mbit/s 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.
