We use the console cables that come with cisco routers on the newer
sun hardware. Using the wrong serial cable is going to break anything
and if it appears to work, the worst thing that could happen is the
flow control is messed up but a fast PC as a termainl running at 9600
baud shouldn't need any flow control.

The serial RJ-45 is the same as with the older SunFire Servers, and
Cisco Routers. You can use the same cables and the same serial console
switch. (Or the Cisco cable you use to connect the Router/Switch to
your Laptop.)

Please No!
A server belongs in the server room with a serial consoleswitch.
A KVM Switch is far more expensive and far less helpfull. You even
can't log the session to a file.
I would rather have Sun or any other manufacturer get the extra money
which would go into a video interface.

A sun sparc is fully manageble through the serial interface.
A sun amd64 is not. (As far as I know.)
