One warning about this: make sure there is an adapter cable connected on BOTH ends of the type 1 cabling; if you have a case where a disconnection is made on one of the IBM connectors, you have a pair of ethernet loopback cables... If your switch is set to full duplex, this may result in a packet accelerator (you will suddenly run to maximal utilization everywhere in that broadcast domain ...) Likewise if you have autonegotiate enabled, and do not disable FD as possibilities, you may find a similar situation. (I have experienced and tracked this down due to some other person's (serial) errors) If you intend to go 100Mb over Type1, I would recommend that you nail your type 1 connected ports to Half Duplex only, that way if something is disconnected improperly, you will not cripple your entire broadcast domain... instead the port will light up like a christmas tree (with collisions)... which I prefer greatly to the alternative of losing a whole broadcast domain....
