Depends on the model.  The compact PCI formfactor boards, along with those
derived from them (Netra t1 model 105) have watchdog timers in the hardware.
I am guessing, but not sure, that anything that Sun sells in the
"Netra" line of telco servers have watchdog timers that can be set.

According to some of the documentation for the Linux support of this,
the watchdog timer is embedded in the compact PCI based sparcs,
as well as any other sparc that uses the RIO chip.

Checking the eeprom settings on a Netra t1, I see the following:
	# eeprom | grep watchdog
	watchdog-timeout=65535
	watchdog-enable?=false
	watchdog-reboot?=false
