AT&T Fiber With Cisco 2921

We had AT&T hook up fiber to our office.  It fiber comes in off a Ciena 3930.

The phone system PRI in the Cisco 2921 is working fine.

However, trying to put into the GE ports shows no link activity.

Why is it not working?

few question:

do you see CD on gig port?
what IOS you are using on CISCO 2921?
Have you set gig port on speed & duplex auto?

show us some int configs & outputs?

This device was simply dropped off my AT&T and said it worked.  My company is now in the process of trying to backfill and fix the issue--with little help or resources.

The GE 0/1 port goes to the fiber box and has link lights.  Plugging in a CAT5 into either other one (which something hot on the other end) to the other GE ports does nothing.
contact you ISP then...it might be hardware issue they put at you place or they need to do some config..change...

tell them about your 2921 and gig port..

it would be good it you show then your gig port config..so they will tell you what exactly you can configure.

guptasan26: Thanks.  That is what I figured.  Without them, I am dead in the water!

guptasan26: In theory, you should be able to jack into the GE port and have connectivity, correct?
