PC Server 315 - Plug and Play
Applicable to: World-Wide
Plug and Play is a technology designed to make expanding the server easier. Plug and Play adapter support is built into the system board in the server. PCI adapters generally support Plug and Play.
Plug and Play Adapters:
Plug and Play adapters are easier to install and set up because they are auto-configuring. This means that there are no jumpers or switches to set.
A Plug and Play adapter comes with built-in identification and configuration specifications set in memory on the adapter that provides installation information to the server during startup. This information is sensed by the input/output (I/O) bus and interpreted by the server Basic Input/Output System (BIOS). The BIOS routines then automatically configure the adapter around the resources already in use by other devices.
Most adapters designed for PCI slots are Plug and Play devices. However, many ISA adapters are not Plug and Play devices. These adapters are discussed in "Legacy Adapters."
NOTE:
If a resource conflict arises after you install a Plug and Play adapter, you might need to change the default resource settings on the adapter. For more information, refer to the documentation that comes with the adapter.
Legacy Adapters
If an adapter that you install is not Plug and Play compatible, the Setup utility program can help you manually configure the adapter. Adapters that are not Plug and Play compatible are known as legacy devices.
Setup Utility Program
Within the Setup utility program, the ISA Legacy Resources screen displays server resources that are typically required by adapters:
- I/O port address
- Memory address
- IRQ line
- DMA channel
From the Setup utility program screens you can select available resources for the adapter you are installing. Resources not currently being used by adapters that are already installed in the server are listed as [AVAILABLE]. The system resources that are in use by other devices are listed as a [SYSTEM RESOURCE].
Refer to the documentation that comes with the adapter for information about required system resources. Then make the appropriate jumper or switch settings on the adapter.
If you have a resource conflict, set the resources used by the ISA legacy adapter to [NOT AVAILABLE]. This will manually configure the ISA legacy adapter to that specific server resource. Once Plug and Play detects that a resource is not available, it will skip that resource, and reconfigure to other available system resources.
