D-Link DFE-690TXD Product Manual - Page 7

Section 1 - Product Overview If the supporting device does not have auto-negotiation functionality, then its monotone (single capability) message will be recognized by the DFE-690TXD's auto-negotiation facility, and the DFE-690TXD will simply switch to the one of its own capabilities which matches that of the supporting device. Once the auto-negotiation is completed, the line is ready, and it will provide an optimal data channel between the DFE-690TXD and the supporting device. The line will remain ready without further auto-negotiation action until the link is broken. Auto-negotiation then reoccurs at any time that the link is restored, again making the line ready for optimal data communications. LED Indicators The DFE-690TXD features 2 LED indicators: • 10 Indicator: a steady light indicates that data transmittal rate is at a fast 10Mbps and that a link is established. • 100 Indicator: a steady light indicates that data transmittal rate is at 100Mbps and that a link is established. • In addition, activity on either 10Mbps or 100Mbps links is indicated through a blinking light. A blinking light indicates that data is being transmitted. D-Link DFE-690TXD User Manual
