| The hub will Automagically connect the 90TS to the flex channel on the
upper connector. You don't have to worry about which one it is.
As far as adding a second card you could only connect it to the same
flex channel as the first one because it also must be on the upper flex
channel.

| When you instruct the hub to connect the 90TS to one of your configured
LANs, the MAM is smart enough to know that for the connection to be
possible, the LAN will have to be on the flex channel on the upper
connector (the only flex channel the 90TS can attach to). If the LAN
you want to attach the 90TS to isn't currently mapped to the flex
channel on the upper connector, the MAM will attempt to shuffle around
the mapping of LANs to flex channels in the hub to achieve your desires.
It may or may not be able to do this, depending on the current
configuration of the hub.

Definitely not. The 90TS can only attach to the flex channel in the
upper connector. So if two 90TS in the same hub are both attached to
flex channels, then they're both attached to the same flex channel (the
one in the upper connector) and therefore are on the same LAN.
The only way for two 90TS in the same hub to be on different LANs is
for one to be on the flex channel in the upper connector and the other
to be on the thinwire.

| Is there any way looking at HUBwatch to identify the flex channel in
the upper connector? Maybe in a future release of Hubwatch/firmware?
Thanks

Virtually no. Almost definitely no.
The only way you could determine which [HUBwatch LAN interconnect] LAN
represents flex0 [in the hub900] would be if you had a 90FS/TS
successfully connected to a [LAN interconnect] LAN. Since the MAM will
only permit the 90FS/TS to be connected to flex0, such a LAN would thus
have to be flex0. This is really just a backwards way of re-phrasing
the rule that two or more 90FS/TS can only be connected (except using
Thinwire) via a common [green] LAN.
There are no plans to inform the user about any correlation between the
LANs they see [in HUBwatch's LAN interconnect screen] and the flex
channels [in the hub900]. In fact, in the future we'd like to distance
the customer from the details of the hub's flex channels even more.
Aside from the 90FS/TS rule stated above, is there any other reason the
customer should be concerned about what specific flex channels are used
by the MAM to build their LANs?

| Thanks for the reply Carl.
If a customer has a DEChub 900 with some 900 repeaters connected to a
few flex channel ethernets, and they add a 90TS and want to connect it
to a particular LAN group....Will the MAM shuffle aound the flex
channel configuration to make the connection?
Thanks,
Dave

| Yes. The MAM will do the right rearranging if possible.
