This section covers the LEDs on the 8-Port TX Module, displayed in Figure 14.

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.

Act

The Act (activity) LED flashes to indicate the port is transmitting and receiving data. The LED is dark if there is no activity.

100/10

The 100/10 LED indicates the speed of the port. All 10/100-TX ports auto-negotiate the speed by default. The ports can be manually set for a particular speed. Green indicates the port is running at 100 Mbps.

The 100BASE-FX ports do not support 10 Mbps. The 1000BASE-SX port only supports 1000 Mbps.

Full/ Half

The Full/ Half LED indicates the duplex mode the port is in. The LED is lit when the port is in full duplex and dark in half duplex.

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.

The LED status is summarized in Table 4: 8-Port TX Module LEDs.
