3.1 Handling cPSB Cards
All of the cards in a Netra CT 820 server are cPSB cards.
Caution – The system is sensitive to static electricity. To prevent damage to the
assembly, always connect an antistatic wrist strap between you and the system.
Caution – Do not flex the cPSB cards; the surface-mounted components can break if
the card is bent.
To minimize the amount of card flexing, observe the following precautions:
■
When removing a card from an electrostatic discharge bag, keep it vertical until
you place the card on the electrostatic discharge mat.
■
Do not place a card on a hard surface. Use a cushioned antistatic mat. The card
connectors and components have very thin pins that bend easily.
■
Be careful of small parts located on the component side of a card.
