Section 4 - Cable Diagnostics

Cable Diagnostics

The Cable Diagnostics function helps network administrators to diagnose network connectivity issues. This function is initialized 

when the switch is first powered on. Each port is scanned to determine if the Ethernet cable and connectors are in good working 

order. This diagnostic test looks for two types of common faults in Ethernet cable: an open circuit or a short circuit. An open 

circuit is usually caused by a lack of continuity between the pins at each end of the Ethernet cable or a disconnected cable, 

while a short circuit occurs when two or more conductors have an unintended connection. Either of these common cable 

faults will be detected by the Cable Diagnostics function. 
During the diagnostics the LED for each port blinks green in sequential order. If a cable fault is detected, the corresponding 

port’s Link/Act/Speed LED will light amber. Once the cable diagnostic function has completed, the switch then proceeds with 

normal operation. 

NOTE:

 

the Cable Diagnostics function does not detect the length of Ethernet cabling. Remember that the length of 

cabling between two Ethernet devices may not exceed 100 meters (or 300 feet).
