Complete the following steps to install the SC Express module while referring to Figures 1
and 2:
Note To maintain forced air cooling in the PXIe system, refer to the Maintain
Forced-Air Cooling Note to Users.
1. Plug in your chassis before installing the NI PXIe-4339. The power cord grounds the
chassis and protects it from electrical damage while you install the module.
2. Make sure the chassis is powered off.
Caution To protect yourself, the chassis, and the NI PXIe-4339 from electrical
hazards, leave the chassis powered off until you finish installing the NI PXIe-4339
module.
3. Touch a metal part on the chassis to discharge any accumulated static electricity.
4. Identify a supported PXI Express slot in the chassis. SC Express devices can be placed only
in PXI Express Peripheral slots, PXI Express Hybrid Peripheral slots, and PXI Express
System Timing slots. Refer to the chassis documentation for details.
Figure 1. Symbols for PXI Express/ PXI Express Hybrid/ PXI Slots
5. Remove the filler panel, and touch any metal part of the chassis to discharge static
electricity.
6. Place the module edges into the module guides at the top and bottom of the slot.
Caution When installing the module, make sure both edges are positioned inside
the guides and that the module components do not come into contact with adjacent
modules.
7. Slide the module along the guides until it reaches the rear connector then seat the module
by pushing the front panel until it is flush with the front panel of the chassis.
