D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch
7
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 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.
