Follow these instructions, and refer to Figure 1 to replace the failed module.

1.

Ground yourself with a grounding strap or a ground connected to your 
PXI chassis. Properly grounding yourself prevents damage to your PXI 
module from electrostatic discharge.

2.

Remove the four Phillips-head screws and nuts that fasten the NI 2591 
relay module to the module carrier.

3.

Remove the hex nuts and washers from the SMA connectors on the 
front panel.

4.

Remove the PXI ejector handle screw that secures the front panel.

5.

Remove the module from the base card.

Note

You can order an RF 2591 replacement relay module for your NI 2591 from 

National Instruments. The replacement kit contains the fully assembled module.
