If a cable is plugged into the port and the Link LED is off, check the cable and connection. The default value is that all ports auto-negotiate the proper speed and duplex mode. If the port has been manually configured for a particular speed and duplex mode, verify that the speed and duplex mode of the port match the speed and duplex mode of the device you are connecting to. The color of the Link LED indicates the port's speed. Orange indicates the port is operating at 10 Mbps. Green indicates the port is operating at 100 Mbps.

Link
The Link LED indicates there is a link at the port. If a cable is plugged into the port and
the Link LED is off, check the cable and connection. The default value is that all ports
auto-negotiate the proper speed and duplex mode. If the port has been manually
configured for a particular speed and duplex mode, verify that the speed and duplex mode
of the port match the speed and duplex mode of the device you are connecting to.
The color of the Link LED indicates the port’s speed. Orange indicates the port is
operating at 10 Mbps. Green indicates the port is operating at 100 Mbps.
Duplex
The Duplex LED indicates the duplex mode the port is in. All 24 ports, and the expansion
modules, auto-negotiate the duplex mode by default. Each port can be manually set for a
particular speed and duplex mode. Off indicates the port is in half duplex mode. Green
indicates the port is in full duplex mode. Full duplex means the port is transmitting and
receiving data simultaneously. Half duplex means that data is only being transmitted or
received in one direction at a time.
