D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch
6
Comprehensive LED indicators display the conditions of the Switch and
status of the network. A description of these LED indicators follows
(see LED Indicators). The LED indicators of the Switch include Power,
Link/Act, 1000Mbps and 100Mbps. The Cable Diagnostic functions of
the Switch are indicated by a combination of the Speed and the Link/Act
LEDs, as described below.
Power Indicator
This green indicator illuminates when the Switch is receiving
power.
Link / Act
This green indicator illuminates steadily when a port is
connected to a station successfully and has a good link. The
indicator will blink to indicate that a port is transmitting or
receiving data on the network.
Speed —
100Mbps/amber; 1000Mbps/green; 10Mbps/off
This indicator is green when the port is connected to a
1000Mbps Ethernet station. It is unlit when the port is
connected to a 10Mbps Ethernet station or 100Mbps Fast
Ethernet station.
Cable Diagnostic − LED Indications
When the Switch is first powered on, the Cable Diagnostic
function is initialized and run. The Cable Diagnostic
function will detect three 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), a short circuit
(two or more conductors short-circuited), and the checking
of connectivity for each of the eight wires of a cable to
ensure its capability for running 1000Mbps. Any of these
common cable faults will be detected by the Cable
Diagnostic function and the LEDs will display the results of
the Cable Diagnostic function as follows:
Open, Short, or Improper Connectivity − Speed LED:
Amber − Link/Act LED: Off
