Titolo: Router rotto?

Salve a tutti,
premetto che sono quasi totalmente a digiuno nel campo.
Mi e' stato prestato un router Cisco "dubbio", non si sa se e'
funzionante al 100%.
Io l'ho resettato e configurato seguendo passo-passo le indicazioni su
www.areanetworking.it
Quello che mi perplime e' che a quanto pare il router non aggancia la
portante: nel pannello anteriore ci sono 3 led (CD - RXD - TXD) e sono
tutti spenti.
L'interfaccia ethernet e' ok.
A questo punto vi chiedo: come faccio a capire se il router non
aggancia la portante perche' e' rotto o perche' sbaglio qualcosa?

Posta uno show run....
Magari il router č semplicemente con l'interfaccia ATM0 in shutdown.
Cos'č, un 837?

Mm, devo chiedere: c'e' scritto Cisco SOHO series.

Uhm! Prova a togliere quel
no ip routing
Che mi suona molto male!!!

Prova cosi:

 no atm ilmi-keepalive

no sh
******************************
se la porta atm è bloccata con " no sh" dovrebbe sboccarsi. fammi sapere 

 se la porta atm è bloccata con " no sh" dovrebbe sboccarsi. fammi sapere
anzi fallo prima sul controller dsl 


cosa intendi?
io sono entrato in conf t e sull'interfaccia ATM 0 ho dato: no sh
poi ho fatto reload
ma purtroppo il cisco non si allinea.
puo' dipendere dall'encapsulation?
grazie :)
