Cisco Catalyst 3920 Token Ring

Does anybody remember Token Ring? I have a Cisco Token Ring Switch and a 3Com Hub 16M. I want to use toiken ring fiber transceivers to extend the hub, but when I try this between a patch fiber cable I only get insertion on the Cisco Switch and not the HUB. Any Ideas??

Re: Cisco Catalyst 3920 Token Ring

The Ring In / Ring Out (RI/RO) ports may need to be enabled. In some cases it's a dipswitch, in other caes it may be a console command.

You (usually) cannot use the RI/RO into a standard host port ... RI must go to RO, RO must go to RI ...

I'm also assuming that you have properly crossed the Tx/Rx, and made sure the cable is good.

Also note that you may need to manually set the ring speed on either or both components.

Good Luck

Make sure the speeds are the same on both ends , you had 4 meg token ring and 16 meg token ring . If they don't match you won't get a connection . My condolences on having to still run token ring .
