Installing the NI 9901 on a Chassis

If you are installing the NI 9901 on a chassis that does not provide mounting holes at both
ends of the chassis, you must install the adapter bracket on the back of the chassis.
What to Use
• Adapter bracket appropriate for your chassis
• M3 screws appropriate for your chassis
• Screwdriver, #1 Phillips or T-10 Torx, depending on your chassis, user-provided
What to Do

they are the correct depth and thread for the panel mounting plate. Refer to the
chassis documentation to determine the correct screw size.
