Figure 1-2 LANVIEW LEDs
The following discusses the function of each LANVIEW LED on the
FOMIM (Figure 1-2). Note that there is one Link OK (LNK) and one
Receive (RCV) LED for each port on the MIM, as well as one Error
(ERR) and one Collision (CLN) LED for the entire MIM.
Link OK (LNK) LED
When lit, this green LED indicates that a link has been established
between the receive circuitry of the FOMIM and the transmit circuitry of
the fiber optic device at the other end of the link segment. This LED
remains lit as long as the link is maintained.
Receive (RCV) LED
When lit, this yellow LED indicates that a data packet is being received
on that port. The flash of the LED is pulse stretched for viewing effect.
Collision (CLN) LED
When lit, this red LED indicates that a collision is occurring on one of the
fiber segments attached to a fiber optic port on the FOMIM. The flash of
the LED is pulse stretched for viewing effect.
