unable to access VLAN Management Port Dell N2024

hi all ,

    need help how to change the management vlan 1 to vlan 80 that i created . The CLI Command not same as power connect 6224 as follows :

enable

configure

ip address vlan 80

(this does not work with power connect dell N2024)

I need to access this switch instead of using hard wire patch cord to port 24 (VLAN 1) port 1 to 23 (VLAN 80)

thanks for the help
