Section 2 - Product Overview
The Cable Diagnostic function operates only during the Switch boot up (when the Switch is first powered on). The
Cable Diagnostic first scans the five Ethernet ports to determine if the Ethernet cable is in good working order. This
process is indicated by the Speed LED blinking green for each of the five ports, sequentially. The initial port scan takes
about 10 seconds. If a cable fault is detected, it is indicated by the corresponding port’s Speed LED glowing amber for
5 seconds, after the initial port scan. The Switch is then reset for normal operation. It takes about 2 seconds for the
Switch to reset. The entire Cable Diagnostic process takes about 17 seconds from the time the Switch is booted. So,
from the time power is first applied to the Switch, about 17 seconds is required before the Switch will begin normal
operation.
NOTE:
There is no display of cable faults detected by the Cable Diagnostic during the normal operation of the Switch,
only when the Switch is booted up or power-cycled.
NOTE:
The Cable Diagnostic function does not support 10M/100M. If the port is connected to a 10M/100M device, see
the Link LED to check if the cable is good or not.
