You can perform cable diagnostics for all ports or selected ports to diagnose any cable faults 
(short, open etc..) and feedback a distance to the fault. 
 

•  Cable Diagnostics – Cable diagnostics is performed on a per-port basis. Select the port 

number from the drop-down list. 

•  Cable Status – Shows the cable length, operating conditions and isolates a variety of 

common faults that can occur on Category 5 twisted pair cabling.  

 
Note: Due to a hardware issue Port 8 cannot display cable diagnostic information.
