An odd choice of server for an HA environment wouldn't you say? That unit is
nothing more than a desktop, it really doesn't have redundant anything...

Anyways, you can also use an snmp agent to down a switch port(s) that the
server is attached to, I wrote one in the early 5.x days and it worked well. The
cluster wiki had good docs. But that assumes you have a managed switch
behind it.
