Checklist

Single-Port Power Over Ethernet Adapter User’s Guide 3-3

The Single-Port Power Over

Ethernet Adapter operates and

the load device works, but

there is no data link.

Verify that the indicator for the port is “on.”

Verify that the Single-Port Power Over

Ethernet Adapter is connected to the Ethernet

network with a good connection.

Verify that the Ethernet cable is Category 5 or

greater, and is less than 100 meters in length

from the Ethernet source to the load.

Try to connect a different device over the

same port. If it works and link is established,

there is probably a faulty data link in the load.

If possible, try to connect the load device into

a different unit. If it works, there is probably a

faulty output or input port in the Single-Port

Power Over Ethernet Adapter or a bad RJ45

connection.
