NEC 120Lg manual PCI Boards, PCI Slot Designations

PCI Boards

The server contains six slots into which PCI boards can be inserted. See Figure 4-42.

IMPORTANT: PCI boards are easily affected by static electricity. Handle a PCI board after making your body contact with a metallic frame section of the server to discharge the static electricity on your body. Do not make bare hands contact with terminals and components on the PCI board. In addition, do not put the PCI board on a desk directly. See "Static Precautions" in this chapter for details of the static electricity.

NOTE: When a PCI board is installed, removed, or removed from the present slot and then installed in another slot, modify the detailed settings including the interrupt lines (IRQ) by using the BIOS setup utility SETUP if necessary. See Chapter 4 for the settings of the interrupt line states and I/O spaces at the shipment of the server.
