Using The Show-Sensors Command At The Openboot Prom; Environmental Monitoring Application Programming - Sun Microsystems Netra CP2500 Programming Manual

Using the show-sensors Command at the
OpenBoot PROM
The show-sensors command at OpenBoot PROM displays the readings of all the
temperature sensors on the board. A sample output for typical sensor readings for a
Netra CP2500 is as follows:
