Before installing the board
Installing and Removing
• The PCI board/PCI Express x16/x1 board (PCI board) is very vulnerable to static
electricity. Touching the PCI board when your body contains static electricity may
damage the board. Before touching the board, eliminate static electricity by touching
a metal object such as an aluminum sash or door knob.
• Do not touch the PCI board port. This may cause poor connections or damage.
• Please be careful not to touch the parts on the board or the solder-mounted areas.
• Forcefully inserting the PCI board in the wrong direction may cause damage to the
connector port of the computer and the PCI slot/PCI Express slot x16/x1 (PCI slot).
• Make sure your PCI board is compatible with this computer.
• Do not touch any other internal parts or switches inside the machine.
• Before mounting or dismounting memory of PCI slots, disable the "Fast Startup"
function. For more detailed information, please refer to "Disabling the "Fast Startup"
function" (p.23).
