I've seen this problem when a port on the MAU needed to be reset. Or when
the ring speed is set incorrectly. To reset the port on the MAU, they sent
me a handy little tool that fit into the MAU port and a little red light
blinked on it when it was done. I've lost it now, does anybody know what
these are called? magic-token-ring-pez-dispenser-resetters?

Subject: Re: TR Int Errr [7:6112]
Hello Gang - I am having problem bring up TR int. Following is the debug
output.
R2502#debug token ring
Token Ring Interface debugging is on
R2502#
02:46:48: %TR-3-OPENFAIL: Unit 0, open failed: Phys. Insertion, ring
beaconing
02:46:50: TR0 starting.
02:47:12: %TR-3-OPENFAIL: Unit 0, open failed: Phys. Insertion, ring
beaconing
02:47:14: TR0 starting.
02:47:35: %TR-3-OPENFAIL: Unit 0, open failed: Phys. Insertion, ring

02:47:59: %TR-3-OPENFAIL: Unit 0, open failed: Phys. Insertion, ring
beaconing
02:48:01: TR0 starting.
I browsed through cisco site to figure out what is the problem with TR based
on above debug output. Following is the answer. Can somebody help me to
bring up the TR.
Ring Beacon The interface is transmitting beacon frames onto the ring.
Something is wrong with the ring.
