Re: Token Ring to Ethernet
Yes, we are doing the same thing, although we are using patch cables with IBM connectors on one end and RJ-45 on the other. The only problem is if you are using 2924XL switches. If you are using those, and someone disconnects a patch cable form the wall, the type 1 connector loops back (this prevents open ports in a MAU) and freaks out the 2924XL port. There is an open bug on this, but no solution as of yet. I'm not sure if it affects any other switches. Cisco actually did a study and concluded that Type 1 cable is fine for 100Mb ethernet.

Re: 100mb Ethernet over Type 1 ... [7:4897]
Yes, we've been doing it for a couple years. The only issues we have run into are with using 2924XL switches. When you are running token ring, the connectors automatically loopback when they are disconnected so that the ring is not broken. The 2924XL switches have a bug that causes the port to freak out when the connector loops back. The only way to fix this is to reset the switch. You have 2 options - 1. Make sure everyone knows not to disconnect the IBM connector end of the cable until it has been disconnected form the switch, or 2. remove/cut the think wire inside of the connector that causes the loopback. Just make sure you never need to use the connector in a token ring network again or you will have problems. Other than that, we've had surprisingly few problems...
