LANVIEW LEDs

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.
