Installing VXI
Modules
Install C-size modules directly into the mainframe by first placing
the module’s card edges into the front module guides (top and
bottom). Slide the module to the rear of the mainframe until the
module connectors mate solidly with the backplane connectors.
Secure the module’s front panel to the mainframe using the
module’s front panel mounting screws.
The easiest way to install B-size modules is with a “B to C-size
adapter” allowing a B-size module to be installed just like a C-size.

(Airflow
Directors)
In order to improve cooling of used slots in the VXI mainframe, a
limited number of airflow directors, P/N 456271, may be installed
at empty slot locations to redirect otherwise wasted airflow.
CAUTION
To maintain a balanced airflow throughout the
system when using airflow directors, do not cover
more than six empty slots at any time. If module
density is low, space airflow directors evenly across
the mainframe.

Select the slot to be covered by the director, and place the

top of the director (with the other hand) at the rear may be
required to engage the hook into the cardguide.
