"404 not found" - N1548P

Bonjour,

Je tente de configurer un switch DELL N1548P tout juste sorti du carton. Après avoir fait la configuration (vlan, adresse IP, authentification) je n'arrive pas à me connecter à la page web du switch. Le message "404 not found" apparait. A ma connaissance, le serveur http est activé par défaut.

J'ai restauré la configuration usine,mais le problème persiste.

Voici ma running-config
