C-5 Ethernet Power Supply User s Guide
The end device
operates, but
there is no data
link
(continued).
• Connect a different end device to the
same port. If this works and the link
is established, there is probably a
faulty data link in the end device.
• Re-connect the end device to a
different "Data & Power" port and
remember to move the "Data" port of
the switch or hub accordingly. If this
works, there is probably a faulty "Data
& Power & Power" or "Data" port in
the Ethernet Power Supply or a bad
RJ-45 connection
One of the ports
is powering an
end device
without turning
the Port LED on.
Re-connect the end device to a different
"Data & Power" port. If the LED turns on,
there is a fault in the previous output port
(probably a faulty LED).
Is it safe to keep
the Ethernet
Power Supply
running while
the "Power Not
Active" port LED
is orange?
Yes, this condition is safe.
