SES Controller Card

A manual override of the fan speed control is available for special circumstance
environments. Referring to the illustration on the preceding page, two jumpers
are provided on the fan module printed circuit board to override the firmware
control of the fan speeds. This hardware setting provides full voltage to the fans
for maximum operational speed, which is greater than the maximum speed set
by the automatic software control. This configuration is normally used when fan
speed noises are not an issue, and the ambient operating temperature is at or
above 30°C (86°F), thus ensuring that maximum available cooling is being
provided.
The jumpers JP1 and JP2 by default are offset, which enables the automatic fan
speed control. Placing the jumper on both pins for each jumper will override the
automatic setting and configure the fans to maximum power.
