Installation and Configuration
Chassis Ambient Temperature Definition
Setting Fan Speed
The AUTO/HIGH fan-speed selector switch is on the rear panel of the M9005A.
Refer to
for maximum cooling performance (recommended) or AUTO for quieter
operation. When set to AUTO, the fan speed is determined by chassis intake air
temperature.
Installing EMC Filler Panels
To improve module cooling performance, install EMC filler panels (part number
Y1213A) in unused or empty slots. Secure with the captive mounting screws
provided.
Installing Slot Blockers
The cooling performance of the chassis can be improved by installing optional
slot blockers (part number Y1212A).
Rack Mounting
Rack mount applications require the optional rack mount kits available from
Keysight. Refer to
rack mount kits to install your chassis in an instrument rack.

The chassis fan control system uses intake air temperature as the input for
controlling fan speeds when in Auto Fan Speed mode. Because of this, the
chassis ambient temperature is defined as the temperature that exists just
outside of the fan intake vent on the bottom of the chassis. Note that this
temperature may be higher than ambient room temperature depending on the
surrounding equipment and/or blockages present. It is the user's
responsibility to ensure that this ambient temperature does not exceed the
rated ambient temperature as stated in the
Slot 6 will have higher temperature rise than other slots.

High power PXI modules should be installed in slot 2, 3, or 4 with
the fan speed set to HIGH.
