■In a hot swap installation, you can install the adapter while the system is running, without interrupting the operation of the server. Depending on the level of hot swap your server is running (full or basic), you may be required to enter software commands before and after the installation.
■In a cold installation, you must shut down the operating system and power down the system before installing the adapter. After the installation, you must power the system back on for the system to recognize the new adapter.
Note
Models of Hot Swap
Hot swap, a key feature of the PCI Industrial Computer Manufacturers Group (PICMG) standard, means that a CompactPCI adapter that meets the PICMG standard can be reliably inserted into or extracted from a powered and operating CompactPCI platform without affecting the other functions of the platform. The standard also defines state transitions fro the hardware and software connection processes that allow the card to be connected and configured.
The adapter supports two models of hot swap:
■Basic hot swap
■Full hot swap
The models can be explained by first defining the following processes:
■Hardware connection
■Software connection
In the basic hot swap model, the hardware connection process can be performed automatically by the hardware, while the software connection process requires operator assistance.
In the full hot swap model, both the hardware and the software connection process are performed automatically.
If you install the adapter in a server set to full hot swap mode, you will not need to type in any software commands during the installation. However, if you install the adapter in a server set to basic hot swap mode, you will need to type in software
