D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch
4
The Cable Diagnostic first scans the eight 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
eight 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.
There is no display of cable faults detected by the Cable Diagnostic function during the normal
operation of the Switch.
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.
