Cable Diagnostics
When the Switch is booted up (when the Switch is first powered on),
the Cable Diagnostics function is initialized and run. The Cable
Diagnostics function will detect two common faults in an Ethernet
cable connecting the Switch to a remote network device: an open
circuit (a lack of continuity between the pins at each end of the
Ethernet cable or a disconnected cable), and a short circuit (two or
more conductors short-circuited). Any of these common cable faults
will be detected by the Cable Diagnostics function and the LEDs will
display the results of the Cable Diagnostics function as follows:
Open or Short circuit
-
Link/Act/Speed:
Amber
Cable Connection in good status
-
Link/Act/Speed:
Green
During the diagnostics, each port is scanned to determine if the
Ethernet cable and connectors is in good working order. During the
diagnostics process 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. The Switch then goes for 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).
