Corrective Steps
End device
operates, but
there is no data
link.
1. Verify port indicator on front panel is
continuously lit.
2. If an external power splitter is in use, replace it
with a viable splitter.
3. Verify that for this link you are using a standard
UTP/FTP Category 5 straight (non-crossover)
cabling, with all four pairs, and that link is 100
meters long or less.
4. Try to reconnect the same PD to a different port
on the same Midspan or on another one. If it works,
there is probably a faulty port or faulty RJ-45
connection.
