Force10 Stacking, backups and HTTP

Hi,

We have 2 Force10 48S switches that are stacked. I can connect to the management interface, but HTTP is not enabled. My questions are as follows:

1. When i connect, I connect to unit 1 ..If I backup to TFTP (which works fine) ..do I also need to somehow connect to unit 2 and do the same from there?

2. HTTP cannot be enabled, if i run #http-server http I get the error:

% Error: minihttpd not installed

Are we missing something? Is there some license or something that we did not purchase?

Sorry if its in the wrong place, i've just seen a post that said the Force10 forum isnt ready yet?

Kind Regards,

Jon
