Adapters Adding an adapter, such as a communication adapter, extends the capabilities and power of the server. For example, you can add a RAID (redundant array of independent disks) adapter that can enhance logical-drive capacity and performance. Adapter considerations: The Netfinity 5000 supports ISA and PCI adapters. You can install up to six adapters in the connectors on the system board. The system board in the server contains 16-bit, ISA-bus expansion connectors and 32-bit, PCI-bus expansion connectors. One of the expansion slots is a shared PCI/ISA slot. One of the expansion slots supports only ISA adapters. The remaining four slots support only PCI adapters. The server supports only 5.0-volt adapters on the PCI bus. Notes 1. You can install PCI adapters in slots 1-5. Slots 1-4 are on PCI bus 2, slot 5 is on PCI bus 1. Both PCI buses are primary buses; when the system scans the buses to see what devices are on them, it scans PCI bus 1 first. 2. You can install ISA adapters in the slots 1 and 2. Note: If an ISA adapter is not a Plug and Play device, you must allocate the system resources that the adapter will use. Use the Plug and Play choice in the Advanced Setup selection of the Configuration/Setup Utility program to allocate resources. The following figure shows the location of the PCI and ISA expansion slot connectors on the system board. 5 PCI 4 PCI 3 PCI PCI 2 ISA PCI 1 ISA 56 Netfinity Server HMM
