LANVIEW LEDs
The Token-Ring adapters incorporate Cabletron’s LANVIEW
diagnostic LEDs. These LEDs help you diagnose problems, such as
failure to establish a twisted pair link between the adapter and a
device at the far end of the link. Individual LEDs advise you when
the adapter is sending and receiving data packets, when wire
faults occur in the lobe link, and Token-Ring operating speed.

•
Activity LED
This yellow LED flashes to indicate that the adapter has
detected minimum signal strength, is active on the Token-Ring,
and is transmitting, and receiving data addressed to it.
•
4 Mbit LED
This green LED indicates 4 megabit Token-Ring speed.
•
16 Mbit LED
This yellow LED indicates 16 megabit Token-Ring speed.
•
Bicolor LED
When off, this LED indicates that the adapter has not inserted
Phantom into the Token-Ring.
When green, this LED indicates Phantom has been inserted into
the Token-Ring, and there is no wire fault.
When red, this LED indicates Phantom has been inserted into
the Token-Ring and there is a wire fault present.
