D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch
Cable connection good − Speed LED: Green − Link/Act
LED: Off
The Cable Diagnostic function operates only during the Switch boot up (when the Switch is first powered on).
The Cable Diagnostic first scans the 16 or 24 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 16 or 24 ports − sequentially. The initial port scan takes about 3 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 10 seconds from the time the Switch is booted. So, from the time power is first applied to the Switch, about 10 seconds is required before the Switch will begin normal operation.
Note: There is no display of cable faults detected by the Cable Diagnostic function during the normal operation of the Switch, only when the Switch is booted up or
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.
