NEC 320Lb-R manual Installing PCI Adapter Boards, PCI Adapter Board Expansion Slots

Installing PCI Adapter Boards

This subsection describes how to install PCI adapter boards. Use these procedures when adding or replacing PCI adapter boards in your system. When adding, but not replacing a PCI adapter board in a PCI module an identical PCI adapter board must be added to the other PCI module to continue total system redundancy and mirroring.

Notes: All installed PCI adapter boards must have the same specifications and performance characteristics in order to provide total system redundancy and mirroring.

The PCI module board, is located in the PCI module and can have up to two 64- bit PCI adapter boards and one 32-bit adapter board installed in its expansion slots. However one VGA video board is already installed in each module in the standard configuration. See Figure 4-25.

Note: PCI expansion slot #1 is dedicated to the standard video graphics board.

!CAUTION

Electrostatic discharge (ESD) can damage components; place them on an antistatic surface. Only handle PCI adapter boards using an antistatic wrist strap attached to chassis ground.
