How to Replace the Fuses
The front panel LEDs show the status of the +5 V and +12 V fuses. If an
LED is on, the corresponding fuse is intact. Complete the following steps
to replace a fuse.
1.
Ground yourself with a grounding strap or with a ground to your PXI
chassis. Proper grounding prevents damage to your PXI module from
electrostatic discharge.
2.
Power off the PXI chassis and remove the module with the blown fuse.
3.
Remove the blown fuse with pliers and replace, as shown in Figure 1.
