Two Network cards for redundancy

Hi all,
The 520 we've got came with two ethernet cards, and as I understand they
were configured so that they both worked with the same IP address. This
to introduce redundancy in case one failed (and perhaps to spread the
load?). Then, when we restored our old system onto the 520, the network
config got broken and I just set it up with one network card.
I'm going to have a go tomorrow at setting up the dual-card option
tomorrow, but I can't work out how. I guess that you give each ethernet
line it's own TCP/IP interface with a unique IP address, but I can't
find where to specify the third IP address - the IP address you want
both cards to 'pretend' to be. Can anyone help?
Also, we have some fairly fancy HP switches - do I need to configure
them so that they know about this special setup?
Cheers
Guy
