We've recently moved and the last tenant in our new space left behind a 2811
5 Switch. I've downloaded the manual, read as many posts as I can find onlin
e and have the switch working relatively well. The software version is up to
date, I've cobbled together a service cable, and have it switching local tr
affic.

I know it's archaic, but it should work well for the cluster of workstations
we use for our interns and co-op students.

My question, and I can't believe I haven't been able to find an answer, is h
ow to connect it to a router so that connected workstations can access the I
nternet. I'm not doing anything fancy and will put a simple Linksys or DLink
router in front of it, but I can't figure out how to setup an uplink/WAN po
rt. Can any of you please point me in the right direction?

Thank you for your time, any help is much appreciated.

You probably just need to use a cross-over cable, plugged into any
of the ports.

Unfortunately, not that easy. Thanks though.

Andrew,

I am not sure what the nature of your problem is. First things first -
remember that you will need to hard configure the ports of this device
for speed and duplex settings - as well as the connected devices!. I
remember trouble when the device boots up it sends out some signals
which confuse newer devices in their auto~ settings. So set everything
by hand through our network, if you want to be sure.

Since it is a layer2 switch you will need to configure the WS and the
router to be in the same subnet and set the router as default GW. if
you can not ping your router from the workstations you are having a
problem, obviously. You can also try pinging the switch from your
router, If this doesn't work you know that there is a problem right
there. You would need a cross over cable and any port should do.

Beside these basic things I am not aware of any gotchas. Let me know
how you are going with this,

Markus

It isn't? That's odd -- it *was* that easy when I used to run 28115's
myself. I still have two here, and I fired one of them up no more than
8 months ago, and just connected up the wires, and it worked just
fine. I used it as our core LAN switch for a couple of days.

In other words, my experience with them is not ancient and lost in the
mists of time -- I know *exactly* where ours are to within 2 feet
and have recent experience in using them.

The major problem I have with our 28115's is that the four cursor
buttons have worn out and stick badly, and it's now a real pain to
reconfigure through the front panel. But you have your console
connection going, so you don't have to worry about that particular
problem.

Thanks for the all of the advice.

I now have everything working within the LAN (8 workstations are connected
and switching).

I've tried connecting the 28115 to the HotBrick LB2 which is a 2x WAN router
and Gateway, but it won't recognize it at all. I can't seem to setup the LAN
ports on the HotBrick, they are of course setup for auto
negotiation/configuration.

I have been able to connect the 28115 to an old Linksys BEFSR11 we had
laying around, but only when the router is set to cross-over and and I use a
patch cable, does this make any sense? It may be the router, but it was a
working pull from a few months ago.

Sorry for the long post, but I'm at the end of my rope. Is it time to pack
it in and get a new dlink or linksys switch? Or can I get the 28115 working
with my HotBrick?

Thanks for all the help, it's definitely appreciated.

The 28115 never does auto negotiation, so if the LB2 meets IEEE negotiation
specs, it would choose 10 Mbps Half Duplex (which is what should be
used if you cannot negotiate.) My suspicion is that you are trying
to run that particular 28115 port at 100 Mbps.

If you want 100 Mbps between the router and the LB2, then you need
to interpose a switch (or router) that allows you to fix the speed
and duplex for the 28115 link, but will autonegotiate for the LB2 link.

Ceci, ce n'est pas une idée.

---------------End of Original Message-----------------

The 28115 doesn't do autonegotiation; it was developed in
the early 1990's before any standard or practice for dual
Ethernet/Fast Ethernet operation was defined.

What it does do as part of the POST process is test its
PHYs at both rates. This confuses devices set to autonegotiate,
virtually assuring operational mismatch.

What you must do is set up your 'brick' interface to some
hard-configured setting for speed and duplex. Perhaps it can
be configured out-of-band by serial port, or if in-band, you
can connect to it temporarily through a small repeater, or
directly to it with a crossover cable. Then configure the
28115 switch port the same way.

If I missed somewhere in your post that the 'brick' can't be
so configured, then you have no choice but to permanently
interpose a small repeater between it and the switch (or
use a different switch) so that it isn't confused during
autonegotiation.

We installed a new Dell 3324 managed switch and I installed the 28115
between it and the HotBrick LB2 that we're using, the 28115 also switches
out to some low priority servers and VOIP systems. One of the WAN ports on
the HotBrick plugs right into the Dell 3324 the other plugs into the 28115,
initially it wasn't working, but I changed the port on the 28115 to 10MB
half and it started working immediately. Thanks for all of your help and
posts.
