Resetting OBP on Fire V880

Hi,

I've set the OBP variables of a Sun Fire V880 to:

/usr/sbin/eeprom "input-device=rsc-console"

/usr/sbin/eeprom "output-device=rsc-console"

But I can't access the Console by using RSC neither on the serial Port nor on the network.

The machine is not accessable on OS-Level so I need to change the values of "input-device" an "output-device" to the default values.

How can I change this values or reset the OBP without having access to the console or to the OS?

Is the memory which hold's the values resetable by removing any batterie? If yes, where is this battery located?

Thanks a lot in advance.

Steffen
