Step 3: Install the Modules
For applications where the
M9021A provides a cabled PCIe
link between the M9018A
chassis and an external host
computer, install the M9021A in
the system slot (slot 1) of the
M9018A PXIe chassis. The two
switches on S301 must be in
the Target (right) position. This
is the default setting. For con-
necting to a downstream solu-
tion, the M9021A should be
installed in a x8 hybrid slot in
the PXIe chassis (slots 2, 6, 11,
or 15 in the M9018A chassis). In
this case, both switches on S301 should be in the Host (left) position.
If Your Solution Contains a Keysight M9021A Cable Interface Module in
Slot 1
The M9021A Cable Interface Module does not derive power from the
chassis connector used by PXI embedded controllers. Instead, the
M9021A uses the top connector on the chassis backplane for its 3.3V
and 12V power. However, a switch on the M9018A chassis backplane
must be set to supply those voltages to the connector. The default
position of the switch is to the left and does not supply the voltages
to the connector. To use the M9021A in Slot 1 of the M9018A chassis,
you must move the slide switch to the right before installing the mod-
ule. Refer to the M9018A chassis documentation for more inform-
ation.
1. Locate Slot 1 in the chassis. It has the icon (
) above it.
2. Remove the M9021A module from its protective bag. Observe ESD precautions.
3. Hold the module by the injector/ejector handle; guide the module into chassis slot number 1.
a. Install the module into the PXI slot of the chassis by placing the module card edges into the front module
guides (top and bottom).
b. Slide the module to the rear of the chassis and assure that the injector/ejector handle is pushed down in the
unlatched (downward position.
c. Slide the module completely into the chassis. When you begin to feel resistance, push up on the handle to
fully seat the module into the chassis.
d. Tighten the module retaining screws and torque to 5 Lb-In (0.57 N-m).
