Replacing a card
DANGER
Static electricity damage
Wear a wrist strap connected to the wrist strap grounding
point on the frame supervisory panel (FSP) while handling
cards. This precaution protects the cards against damage
caused by static electricity.
DANGER
Do not hold card by levers only
Holding a card by the levers only may result in lever
breakage. Once the card has been pulled half way out of the
shelf, carefully grasp the card underneath for more secure
support and continue to remove the card from the shelf.
Avoid touching any wires or internal parts on the card.
