C2801 router cant read more than 3 WICs?

[jammcrae]

I was attempting to use my C2801 as the hub in a frame relay setup. However I am only able to go up/up on 2 of the 3 devices needed for this topology. Is this a software limitation? Or am I over looking something here?

This is an older 1st generation 2801 I assume ? I remember that you can test the interfaces by putting them in 'loopback local' mode. If the interface is okay, it should come up. Can you give that a try ? What cabling do you have connected to that interface ?

[jammcrae]

I know all WIC modules work on this router because I have switched serial cables between interfaces, however I am unable to get all 3 to work simultaneously

Hello,

it might have something to do with the controller settings. Try and type 'controller' in global config mode and see what options there are.

[Georg Pauwen]

Can you post the output of 'show diag' ?

hi,

the 3 WICs were detected by the show inventory output.

is DCE/DTE terminations correct?

do you have clock rate configured on the DCE interface?
