SYSTem:BLOWer:STATe
<state> sets the state of the fans in the mainframe.
SYSTem:BLOWer:STATe?
returns a string with the state of the fans in the
mainframe. The string is either “FULL” or “VAR.”
FULL means either software control or front panel switch has put the fans at full
speed. VARiable means both software control and front panel switch are at
VARiable.
Parameters

Comments
•
This command can change the state of the fans from VARiable to FULL at any
time. When software control has set the fans to FULL, the front panel fan
switch can be set to variable and the fans will remain at FULL. Software
control can not put a mainframe with its switch set to FULL into a variable fan
state. FULL means that the fans will run at full speed no matter what the
conditions in the mainframe. VARiable means that the enhanced monitor sets
the fan speed based on the temperature conditions in the mainframe and the
temperature limits set by the user.

The mainframe’s power is off, or the mainframe’s fan
switch is set to FULL and the parameter sent was
VARiable. In this case, the fan speed was not set to
variable. Software assertion of FULL (using the

on this error.
