• Disconnect UPS devices. If you have an uninterruptible power supply (UPS) connected to your destination computer, disconnect the serial cable before running Setup. Setup automatically attempts to detect devices that are connected to serial ports, and UPS equipment can cause issues with the detection process.
• Back up your servers. Your backup should include all data and configuration information that is necessary for the computer to function. It is important to perform a backup of configuration information for servers, especially those that provide network infrastructure, such as Dynamic Host Configuration Protocol (DHCP) Server. When you perform the backup, be sure to include the boot and system partitions and the system state data. Another way to back up configuration information is to create a backup set for Automated System Recovery.
• Disable your virus protection software. Virus protection software can interfere with installation. Zum Beispiel, it can make installation much slower by scanning every file that is copied locally to your computer.
• Provide mass storage drivers. If your manufacturer has supplied a separate driver file, save the file to a floppy disk, CD, DVD, or Universal Serial Bus (USB) flash drive in either the root directory of the media or the amd64 Ordner. To provide the driver during Setup, on the disk selection page, klicken Load Driver (or press F6). You can browse to locate the driver or have Setup search the media.
• Be aware that Windows Firewall is on by default. Server applications that must receive unsolicited inbound connections will fail until you create inbound firewall rules to allow them. Check with your application vendor to determine which ports and protocols are necessary for the application to run correctly.
