Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide
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.
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.
