LANVIEW LED SIGNALS
If, during normal operation, the LED for a Ring Out port is:
GREEN,
the Ring Out port is active (carrying data) and inserted into
the ring.
BLINKING RED,
the Ring Out port is in a normal inactive state.
This is equivalent to OFF for a lobe port during normal
operation. Refer to Section 1.2.4, Support for Passive MAU
Workgroups, for an explanation of the operational
difference between a Ring Out port and a lobe port.
RED,
the port is disabled by management command.
