Appendix C — Troubleshooting

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.
