2651 router

[tqle]

Does anyone seen this problem before? I was trying to upgrade my router from 2500 series to 2600 series. When I connected T1 line to DSU/CSU the circuit was up and working fine. I was able to connect to my network. However, when I connected pc line on the 16 fastethernet module the T1 went down.

I can't find out what is wrong.

I need help.

Thanks

Hi

is ur T1 goin down all the time whenever u connects u r pc or it happened once ?

r u interfacing u r PC directly to the router or thru any switch ?

just do onething enable loggin console and get into console via u r notepad or anyother pc try to connect the pc again and chek whether u r getting any logs displayed on the screen which may be helpful to find the reason for the T1 goin down..
