  • Page 7 • To help avoid possible damage to the system board, wait 5 seconds after you turn off the system before you remove a component from the system board or disconnect a peripheral device from the computer. • To help prevent electric shock, plug the computer and peripheral power cables into properly grounded power sources.
  • Page 8 • When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins.
