Chapter 1 Watchdog Timer 21
OpenBoot PROM Interface
There is no user interface to the watchdog timer at the OpenBoot
™
PROM level.
When the Netra CP2500 board is in the host slot of a Netra CT 810 or 410 server, the
OpenBoot PROM configures the watchdog timer automatically. The watchdog timer
is armed only when a boot has been started. Once the Solaris OS has booted, the
watchdog timer configuration is changed, based on the Solaris OS configuration.
When the Netra CP2500 board is in a satellite, or I/O, slot of a Netra CT 810 or 410
server, or a third-party cPSB server, the OpenBoot PROM configures the watchdog
timer automatically, but the timer is not armed when the Solaris OS boots. You can
configure the Solaris OS to arm the Netra CP2500 watchdog timer in satellite slots.
