Step 4 - Install the Module
PXI hardware does not support "hot-swap" (changing modules while power
is applied to the chassis) capabilities. Before installing or removing a
module to/from the chassis, power off the chassis to prevent damage to the
module.
M9451A module is factory tested, aligned and shipped as a standalone
module. It can be used in a chassis with PXI-H chassis slots.
Module Installation Process Overview
The module can be installed in any hybrid PXI slot marked with a peripheral slot
compatibility image (solid black circle with the letter -H- for hybrid).
Make sure that the line cord is plugged in to establish earth ground and that
the chassis power switch is Off.
If the chassis has multiple fan speed settings, ensure that the fan switch is
set appropriately for the system. Default setting is AUTO fan speed and the
inhibit set to DEF.
Position the chassis to provide ample space between the chassis fan intake
and exhaust vents. Blockage by walls or obstructions affects the air flow
needed for cooling. (Refer to the chassis documentation for more information
about cooling).
Before inserting a module into the chassis, back the mounting screws out to
ensure that there is no interference between the screws and the mounting
rails.
Keysight M9451A PXIe Measurement Accelerator uses peer-to-peer
(module-to-module) data transfer over the PXIe Express chassis backplane.
Therefore, install the M9451A module into a chassis that supports peer-to-
peer PXI Express data transfer between it and the M9381A or M9391A
modules. For best performance when using the Keysight M9018A PXIe 18-
Slot Chassis, install the M9381A modules into a x8 slot, which are slots 2, 6,
11, and 15.
