Precautions
Observe the following precautions when working on the system, particularly
when handling PCB cards or using test equipment to measure voltages.
• When installing or replacing PCB cards turn power off, but maintain
the ground connections to the equipment (see Note below). Power
must be OFF when inserting or removing cards. These cards are
identified with appropriate warnings on their faceplates.
• Always wear an antistatic wrist strap when handling printed circuit
cards. Handle PCB cards only by the edges and avoid contact with any
exposed electrical connections. When removing a new card from its
package, touch the package to the cabinet frame first to release any
static voltage buildup, prior to removing the card and inserting it into
the equipment.
• Conductive packages (antistatic packaging) should be grounded prior
to opening them to remove the contents, and similarly grounded prior
to placing a card in the package. Place suspected faulty cards in
conductive packages to prevent further possible damage to the cards.
Cards that are not correctly packed in antistatic packaging when
returned will not be covered by any warranty.
