ESD Susceptibility
— Static discharge can cause serious damage to sensitive semiconductor
devices. Avoid handling circuit boards in high static environments such as carpeted areas and when
synthetic fiber clothing is worn. Always exercise proper grounding precautions when working on circuit
boards and related equipment.
Caution
— Ensure the Retaining Bolts are fully unfastened before attempting to remove the PSU
module from the chassis. While the bolts are not removable and serve as a threaded insertion and
extraction tool. It should be free to move in and out a few millimeters in its socket once unfastened.
