| I think you mean it happens on one or two of the LANs. You can't see
the flex channels. Also, by "flexchannels quit working" I take that to
mean that some of the repeaters don't see traffic from the switch. I
think this will help readers understand the problem statement.
I assume the LEDs on the switch show that all ports are forwarding
packets and that you have no loops causing switch ports to go into
standby. Also, I assume when you do a "refresh" on the Lan Interconnect
window in Hubwatch that all the connections are still shown to exist
correctly.
It could be a hardware problem. One or more of the modules may have a
bad backplane driver that is affecting communication between the switch
and a repeater. Or possibly the backplane is bad.
Look for errors on the affected ports (though its not always necessary).
My guess is that it is a bad module, rather than the backplane.
Maybe a LAN gets assigned a different flexchannel each time the hub
reboots (this can certainly happen), so the problem seems to move from
one LAN to another, whichever LAN happens to get the problem channel.

Double-click the repeater. Scroll down the port list to the bottom
where there is a port labelled "BP" (backplane). Click the picture
of the BNC connector.
