Adding a Module
To install an NI or CMM module, follow the steps below.
Important. Before beginning, note that the CMM modules and NI modules slide into the chassis card
guides differently. CMMs have a sheet metal tray that slides into the guides; with NIs, the edges of the
module’s printed circuit slide into the guides.
1 Holding the module in both hands, carefully slide it into the chassis card guide. The component side of
the board should face right.
2 The module should slide in easily. Do not force the module into the slot. If any resistance is encoun-
tered, ensure the module is aligned properly in the card guide. Also, see the important note regarding chas-
sis card guides on page 5-27.
3 When the module is nearly seated in the slot, be sure that the two extractor levers—one on top of the
module and one on the bottom—are slightly opened (approximately 30 degrees). This allows the notch on
each extractor lever to grasp the rail on the chassis. Once the notches have grasped the rail, press both
extractor levers inward simultaneously until the module is firmly seated.
