and cards.
The plug-in boards and cards contain static-sensitive components.
Improper handling of boards and cards can cause component damage.
Follow these precautions when handling boards and cards:
• Turn off electrical power before installing or removing a board.
• Use a static ground strap to ground yourself to the chassis ground before
touching the chassis or a board.
• Keep unused boards and cards in conductive bags. Also, be sure you are
grounded when removing a board or card from a conductive bag.
• Handle boards with their front panel or circuit card edges. Do not touch any
circuit card components, pins, or circuit connection points.
