3-2 Troubleshooting

The Mid-Span Power Hub operates and the 
load device works, but there is no data link.

Verify that the Detect/Power Forwarding (blue) 
LED for the port is “on.” Verify that the Mid-Span 
Power Hub is connected to the Ethernet 
network with a good connection.

Verify that the Ethernet cable is Category 5, 5e, 
or 6 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 a link is established, there is 
probably a faulty data link in the load.

Try to reconnect the load into a different output 
port (remember to move the input port 
accordingly). If it works, there is probably a 
faulty output or input port in the Mid-Span 
Power Hub or a bad RJ45 connection.

The Mid-Span Power Hub operates, but one of 
the ports is powering a load without turning the 
“Power” LED on.

Move the load into a different output port. If the 
LED turns “on,” there is a fault in the previous 
output port.
