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 Warning 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.

Power Supply

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

Warning supply. Allow one minute for the capacitors in the power supply to discharge.

Removal

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.
