x-posted to uk.telecom.broadband in the hope one of the clever people
there will be able to help. And also to alt.comp.networking.routers,
which is not a group I use but sounds hopeful!

Try the console port of the switch, if it has one.

It looks like the default address is 192.168.0.239, have you tried
that? Are you also on the 192.168.0.x network? If not, you'll want to
change your settings temporarily or you won't be able to see the
switch.

It's also possible that the switch's IP address has been changed, of
course. One would hope that it's somewhere within the 192.168.x.x
scope, so scanning in that range might find it. It could also be in
the 10.x.x.x range, among others. If you reset the switch, it should
go back to 192.168.0.239, in case that's an option.

Also worth running a packet capture device, say Wireshark,
and rebooting (turn it on) the switch. It seems that many devices
now do a duplicate address check by ARPing for
themselves before coming on-line. You might get the
address from this or from
other traffic. Not sure if I have every got this to work
but it seems a good theory:-) Make sure that you use a port
that is enabled.

comp.dcom.lans.ethernet was not a bad place for this
sort of thing but it is largely defunct (ethernet now just works:)
and not strictly on topic exactly.

Manual available here :-
ftp://downloads.netgear.com/files/FSxxxT_GSxxxT_smartswitch_UserManual.pdf

This refers to a Smartwizard Discovery program, presumably supplied on
a CD with the new product.

Might also be worth cross-posting in uk.comp.home-networking.

When I had trouble with an old print server box, I ended up resetting it
to defaults before it would play ball.

The odd thing is, I had used it on the same network I reinstated it on
some years (yes years!) previously. But it seemed to have forgotten itself.

Sorry I was not able to read the replies until today.

I have tried the default addresses (including resetting the switch
back to factory defaults).

Looks like I do need that Discovery program. I don't have the CD since
this was purchased used. But maybe the support page at netgear will
have it. I'll keep trying.

At least I found that there wasn't some simple step I was missing.
Just knowing that is a great help.

THANKS ALL.

If you have any spare ports on the Netgear switch try the workstation on
that, because I'm pretty sure piggybacking switches like that causes
problems unless the have uplink ports designated for this, like Cisco 2950
etc.
Was the small switch working before you installed the Netgear switch? If so
then check you've used a crossover cable to connect the 2 switches .. not
straight thru.
