D-Link DGS-1016, DGS-1024 manual Power Indicator

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

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
