Yes, it's called "out of band management". Have dial-in access to IPMI/iLO interfaces or just an APC remote controlled power-switch to power-off the server.
I don't want to reboot the server everytime something like that happens. I'll expect pretty nasty problems will develop after a few dozen unclean shutdowns like that.
Would ILO work on a server that's unresponsive due to heavy load?
ILO used to be a separate board with a separate NIC and a separate CPU etc. Nowadays, it's just an additional chip on the board.
It works until the power-supply is fried.
The actual network access isn't a problem so dial up isn't necessary. The other problem is the server in question probably doesn't have ILO features on the mainboard.
If it's a server that actually deserves that name, it should have IPMI on board. You can buy add-on PCI-cards for OOB-management, though.
