Complete the following sets of steps to disassemble your switch module, replace a failed relay, and reassemble your switch module.
Disassemble the Switch Module
- Ground yourself using a grounding strap or a ground connected to your PXI chassis.
Note Properly grounding yourself prevents damage to your switch module from electrostatic discharge. - Remove the four screws that secure the plastic cover on the top and plastic lead cover on the bottom of the switch assembly.
1 Screws 2 Plastic Cover 3 Plastic Lead Cover - Carefully separate the adhered top cover absorber from the relays by slowly prying up on the cover. (Note: some metal relay caps might come loose during this process and can be put back onto the relays after you have completed relay replacement.)
