Front-Panel LEDs The Model DS508, DS516, and DS524 hubs provide front-panel LEDs for monitoring individual ports and hub status. The following table describes the front-panel LEDs and their functions. Label Color Activity Description Power Collision 10 Mbps Green On Amber On 100 Mbps Amber On Utilization% 10 Mbps Green Blinking 100 Mbps Green Blinking 10M or 100M Green On Link/Receive (built into each Off vista RJ-45 network port) Blinking Power is supplied to the hub. Data collision is occurring on the 10 Mbps network segment (some collisions are normal). Data collision is occurring on the 100 Mbps network segment (some collisions are normal). Indicates the amount of data traffic on the 10 Mbps segment. (If a 100 Mbps user is sending data to a 10 Mbps user, 10 Mbps utilization will be high.) Indicates the amount of data traffic on the 100 Mbps segment. A link is established successfully between the hub and the PC. No data link is established and/or the cable is not connected, is defective, or is the wrong type or the connected network card is not properly set up. There is incoming data on the port. Vista RJ-45 Network Ports with Built-In LEDs The front panel of the Model DS508 hub provides 8 vista RJ-45 network ports, the Model DS516 hub provides 16 vista RJ-45 network ports, and the Model DS524 provides 24 vista RJ-45 network ports. These standard RJ-45 connectors accept two-pair or four-pair Category 5 unshielded twisted-pair (UTP) copper wiring (only two pairs are used). The RJ-45 connector uses an 8-pin interface. Two LEDs are positioned at the top corners of each RJ-45 connector. The left indicator is the 100 Mbps Link/Receive LED, and the right indicator is the 10 Mbps Link/Receive LED.
