3-2 Troubleshooting
The Single-Port Power Over
Ethernet Adapter operates but
one of the powered devices
does not work.
Verify that you are using a standard UTP
Cat. 5 or greater cable, including all 8 wires
(4 pairs.)
Try using a different Ethernet cable. If it works,
there is probably a faulty connection over the
long cable, or a bad RJ45 connection.
Insure that your load device works with an
802.3af compliant product (such as the
RBT-1002, RBT-1602, RBT-4102, and
RBT3K).
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.
