Vista RJ-45 Network Ports with Built-in LEDs
The front panel of the Model DS508 hub provides 8 vista RJ-45
network ports, and the Model DS516 hub provides 16 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.
Rear Panel
The rear panel of a Model DS508 or Model DS516 hub has two LEDs,
one labeled Terminator and one labeled 10/100 Mbps Bridge. The
Terminator LED indicates whether or not the built-in terminator in that
hub is active. The 10/100 Mbps Bridge LED indicates which hub has
the active bridge.
Before you begin installing the hubs, prepare the installation site. Make
sure your operating environment meets the operating environment
requirements of the equipment.
Front-panel LEDs
The Model DS508 and DS516 hubs provide front-panel LEDs for
monitoring individual ports and hub status. The following table
describes the front-panel LEDs and their functions.

Green
On
A link is established successfully
between the hub and the PC.
Off
No data link is established and/or
the cable is not connected, is
