how to manage acl through tftp

Hi

We re migration from our cisco 6505 switches to a stack of powerconnect 8164F and we have problems with the way to manage acl.

In our cisco switchs we used to use the following procedures.

we use to download the acl configuration through tftp.

in the configuration file we have at the beginning of the file for each acl a line like that

no access-list inbound-cnsnet

Then we construct the ACL. It was the only way to be ablr to order directive in the acl.

I m trying to do the same thing on my powerconnect with configuration script. 

Then i have the following configuration

interface Te1/0/9
speed 1000

ip access-group inbound-cnsnet in
exit

I m trying to applying the following configuration script

configure
no access-list inbound-cnsnet
access-list inbound-cnsnet permit ip 195.83.222.0 0.0.0.255 any
access-list inbound-cnsnet permit ip 195.83.223.0 0.0.0.255 any
access-list inbound-cnsnet deny ip any any

But as soon as i apply the script the Interface lose the directive

ip access-group inbound-cnsnet in

Does someone know how to solve that problem?
