Speed/ Link/ Activity LED

The 10/100 Mbps, Link, and Activity are combined into one LED. See Table 5: DES-3224 Speed/ Link/ Act LED.

All ports auto negotiate the proper speed and duplex mode when a cable is plugged in. The 10 Mbps/ 100 Mbps LED indicates the speed the port is working at. The LED is amber when the port is at 10 Mbps. The LED is green when the port is at 100 Mbps.

The Link LED indicates that there is a link at the port. If a cable is plugged into the port and the link LED is off, check the connection.

The Act (Activity) LED indicates that there is transmission (Tx) or reception (Rx) on the port. The LED flashes amber when the port is transmitting or receiving data at 10 Mbps. The LED flashes green when the port is transmitting or receiving data at 100 Mbps.
