Removal and Replacement Procedures

Turn the system’s power off before you perform these procedures. Failure to 
turn the power off before opening the system can result in personal injury or 
equipment damage. Hazardous voltage, current, and energy levels are present 
in this product. Power switch terminals can have hazardous voltages present 
even when the power switch is off. Do not operate the system with the cover 
removed. Always replace the cover before turning on the system.

Prior to performing any of the following installation or removal 
procedures, follow these steps.

1. Attach an ESD strap to your wrist. Attach the other end of the ESD 

strap to the chassis as a ground. The ESD strap must be secured to 
your wrist and to ground throughout the procedure.

2. Perform an operating system shutdown. Turn the AC or DC power 

off and remove the AC cord or DC power lines from the system.

The suggested procedure for the removal and replacement of the power 
supply assembly is as follows: 

Removal of the power supply provides access to high 
voltages. Ensure the power cord is removed from the power 
supply. Allow one minute for the capacitors in the power 
supply to discharge.

1. Turn the power OFF to all equipment and disconnect the power 

cable from the AC power source. 

2. If the MVME956AC chassis is rack mounted, slide it from the rack, 

or if it is a lab benchtop unit, remove the top panel and right side 
panel.
