Management Access List...on Dell Power Connect

Hi, 

I have Dell Power Connect 6224 switch. I have configured three Vlan ie. Vlan60, 70, 80

Vlan60 Ip address:-192.168.60.1/24

vlan70 ip address:-192.168.70.1/30

vlan 80 ip address:-192.168.80.1/30

I want that switch can be access only from vlan 70 which is connected with router Ip address 192.168.70.2/30.

and ip address that i want to give rights to access Switch is 192.168.7.66/24.

Is it possible????

if yes so what command should i use in Management access-list?????
