TR interface card has message "is not up" during boot

Running OpenSuSE 64 bit on a generic PC. During boot I receive the messages:

ifup: tr0 device: IBM 16/4 Token ring UTP/STP controller
tr0: SRB timed out.
tr0: Physical Insertion - Monitor Contention failer for RPL
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
ifup: Cannot enable interface tr0.
ifup-route: interface tr0 is not up

The Token Ring card was configured.
I do have a Ethernet interface and that is working fine.

Further, in network settings under Yast, for the T R interface it has a message of: “16/4 Token ring UTP/STP controller (not connected)”. The TR card is connected to a IBM 8228 hub which is connected to another device though it is not powered up.

What needs to be done to get the TR interface working?

Thank you

This tells me there’s something wrong with the ring - what are you
plugging the token-ring card into, and what other devices are on that
network?

What kind of cable are you using?

The network card plugs into an IBM 8228 and that is connecting to a IBM 3174 control unit. At that time the control unit was not powered up. When the PC is booted I do hear what sounds like relays clicking in the hub. Never used Token-Ring before so this is a bit new to me. Tomorrow I will have powered up the control unit and reboot the PC to see if it matters at all.

Is there a particular reason you’re using Token-Ring? It’s been many
years since it was commonly used.

Is the cable a type-1 cable or UTP?

Yes, it is what the control unit uses. To switch to an Ethernet connection for this unit is expensive. As for the cabling, I will have to check later in the day.

That’s reasonable and fair. :slight_smile:

Sounds good. If it’s UTP (unshielded twisted pair), I’m not sure that an
Ethernet cable will suffice. But if it is UTP, also check to see if the
connectors used are RJ-11 or RJ-45 as that will make a difference IIRC.

The cable is: IBM p/n 6339098 which is a Type I TRDC/DB9m STP adapter cable. Also, the green light on the card does is not lit and the amber light is slowly flashing. Unfortunately I do not have the CD for it which contains a diagnostic utility.

Connecting into the MAU, then, you should have a connection for each
device. Depending on the MAU, you may need to connect ring-in to the
ring-out connector to complete the ring - though IIRC, a ring with a
single break in it should still function OK (used to have this type of
equipment in the computer lab I worked in in college back in the early
90’s).

I also remember that the cable could be difficult to secure in the MAU,
so make sure it’s solidly connected. We used to have students kick the
cables out of the MAUs under the tables all the time.

Does the second device seem to connect into the ring OK? If it does,
make sure it’s connected first as it’ll assume the active monitor role,
which should help with the error message you were receiving on the Linux
box.

Only have one device to connect to. Can I get by without the MAU and use a gender bender? I’ve connected to/from the MAU a few times. One time it should have worked if not connected properly.

Do you know if there is some test I could use with say a volt/ohm meter?

Oh and should the T/R card be plugged into any particular port?

The device only knows if it is connected to the network. I think the only test is to ping the network.

You have to use a MAU with type 1 cables (actually, I think even with UTP
you have to have a MAU) - there’s no such thing AFAIK as a “crossover
token-ring cable”.

> Do you know if there is some test I could use with say a volt/ohm meter?

Not offhand, but a MAU will have multiple ports, so definitely try
different ports and see if that helps - it could be that you’ve got a bad
port. You might also simply have a bad MAU. Do you have any other cards
you can try in the PC?

> Oh and should the T/R card be plugged into any particular port?

Shouldn’t make a difference other than not plugging into the ring in/ring
out ports (which will be at the extreme ends of the MAU).

No indicator lights on that device?
