Installing PXI Modules in the Chassis
Recommended best practices to ensure proper and safe module operating
conditions:
– Ensure proper chassis airflow is maintained
– Select a chassis that provides thermal protection if fans become
inoperable or forced air cooling is obstructed
– Use slot blockers (Keysight Y1212A) and EMC filler panels (Keysight
Y1213A) in empty module slots to ensure proper operating temperatures.
The Keysight Y1214B Air Inlet kit (not for M9010A use) supplies additional
cooling air from the front of the chassis. These accessories optimize
module temperature performance and reliability of test system.
– Monitor the chassis temperatures and fan speeds to determine a balance
of fan noise and cooling performance.
– Do not disable fans. Position chassis to allow plenty of space around
chassis air intake and fan exhaust.
– Place the chassis in a horizontal position such as in a rack or on a bench.
– At environment temperatures above 45°C, set chassis fan speed to high.
The M9018B and M9019A chassis have multiple air intakes located at the lower
sides, lower front, and chassis bottom. Do not block the air intakes or fan
exhausts.
The M9010A chassis has two fans that pull air from the rear of the chassis and
exhausts it out the front and top. Do not block the air intakes or fan exhausts.
PXI hard ware does not support “hot-swap” (changing modules
while the chassis is powered on) capabilities. Before installing or
removing a module into/from the chassis, power off the chassis
to prevent damage to modules.
Inserting modules into the chassis when it is in a vertical position
increases the possibility of bending pins on the backplane and
permanently damaging the chassis. It is recommended that you
insert modules only with the chassis in a horizontal position,
such as in a rack or on a bench. Once the modules are inserted
and secured, the chassis may be used in a vertical position.
However, before moving the chassis to the vertical position,
install all the blanking plates to prevent debris falling onto the
chassis and getting lodged in the backplane connectors.
