Mandatory. Definitely mandatory.

For networking equipment, a console server.
For servers which support serial consoles, dialin modems *and* a spare
NIC. If your system isn't booting up, the NIc isn't really useful.
IP KVMs are useful for systems which don't support serial consoles.

Keep this on a physically separate network if possible.
