Innovative Cooling
Lower maintenance costs
The M9018B and M9019A PXIe chassis utilize an innovative
cooling design that allow them to fit into 4U of rack space.
This represents a 20 percent reduction in occupied rack space,
compared to typical PXI chassis which requires 5U or more for
air-flow. This space can be utilized for an external 1U controller
via PCIe cable, resulting in a system that requires no more rack
space than other chassis with an embedded PC controller.
The M9018B and M9019A PXIe chassis were designed to reduce
maintenance costs. There are no air filters to maintain and the
power supply and fans can be removed while the chassis is
mounted in a rack. This enables the chassis to be serviced, while
keeping DUT cabling and modules in place.
With Keysight’s standard warranty, your investment is protected
by Keysight’s global reach in more than 100 countries (either
directly or through distributors). The warranty gives you conve-
nient standard coverage for the country in which the product is
used, eliminating the need to ship equipment back to the country
of purchase. Keysight’s warranty service provides:
The innovative design includes auto-speed fans to expel hot air
out the back panel allowing other instruments with bottom air
intakes to be placed directly above the chassis. Cool air is pulled
into the chassis from the front, sides, and bottom of the chassis.
Unlike many PXIe chassis, the fan-speed is controlled by using
temperature sensors located on the top of the backplane, in the
path of the module exhaust. This enables the fans in the chassis
to react to actual changes in module temperatures, instead of
ambient air temperature readings used by the typical PXIe chas-
sis. This results in lower module operating temperatures when the
auto fan setting is used.

System monitoring
The M9018B and M9019A PXIe chassis have a complete set of
system monitoring functions for power rail voltages, module
exhaust temperatures, and fan speeds. For temperature mea-
surements, the chassis utilizes eight temperature sensors located
on the top of the backplane, in the path of the module exhaust.
Chassis operating conditions can be monitored via a software API
or the soft front panel interface.
Keysight’s exclusive air-inlet modules (Figure 4) can also be used
to supply even more cool air from the front of the chassis and
direct it to other slots. Given the air outside the rack is generally
cooler than the air inside the rack, this results in more efficient
cooling of the PXIe modules. This option enables the system
designer to decide how to best cool the chassis, providing more
design flexibility than other PXIe chassis.
A DB-9 connector is also available at the rear of the chassis
for remote inhibit and power rail monitoring. The chassis has
configurable alarms that can be monitored via front panel LEDs,
soft front panel interface, or software API.
Designed for large systems
When connecting multiple PXIe chassis together, the power-
sequencing becomes very important especially when an embed-
ded controller is used. The M9018B and M9019A PXIe chassis
have special features built-in to make this easy. Cat 5 cables
with RJ-45 connectors are used to interconnect the chassis. In
a multi-chassis configuration, a user can press a single chassis
power button to enable all chassis in the system to power-up. If
an embedded controller is being used, its chassis will automati-
cally be powered up last. This provides a consistent, repeatable
power-up sequence.
Both chassis also have two front panel trigger SMBs which can
be used for input/output triggers. These trigger ports connect to
the PXIe backplane adding configuration flexibility to the system
when non-PXIe instruments are used or when a particular PXIe
instrument being used can only receive triggers over the PXIe
backplane.
