If you are not able to resolve a problem with your FOMIM, call Cabletron 
Systems Technical Support for assistance (see Chapter 1, Section 1.6, 
Getting Help).

LNK
(Link/ 
Fiber
Port)

Green

When on, a link is 
established 
between the 
FOMIM Fiber port 
and the fiber device 
at the other end of 
the segment. LED is 
on as long as the 
link is maintained. 

If off, the link between the port 
and fiber device has been 
broken.

Check the connectors at each 
end of the segment to ensure 
that they are free of dust. Clean 
the connectors if necessary. 
Reconnect the segment and 
check the Link LED again.

If off, the FOMIM is not 
receiving packets.

Check that the module is firmly 
installed in the MMAC.

CLN

When flashing, a 
collision is being
