fan
Use the fan command to determine whether the fans are on or off and to read the fan
speeds. In the fan command output, the number in parentheses is the counter reading
for the fan. The counter reading is a value provided by the fan tachometer. The system
controller converts the counter reading into a revolutions-per-minute value.
Example 3-22 shows sample output from the fan command for an Origin 3000 server or
Onyx 3000 graphics system.

controller shuts down the brick.
