Ajout carte WAN routeur cisco 1711

bonjour,
j'ai ajouté une carte serie (wic-1 T) a un vieux routeur cisco 1711 afin de le relier à un 2e routeur, pour faire de la redondance .
j'ai bien installé la carte, je la vois dans le show version, mais pas dans le show run.
pourtant d'après le site de cisco mon routeur est compatible pour toutes les versions d'IOS (https://www.cisco.com/c/en/us/support/docs/interfaces-modules/1700-2600-3600-3700-1-port-serial-wan-interface-card/7265-hw-1t-wic.html#req)
ya t'il un moyen d'activer la carte manuellement?
ma config:

show run
