Finally, there are a few last steps to take before launching the installation:
Make sure the server is sized appropriately for the load under which you plan to place it. For more information on server sizing, see Chapter 3.
If you’re installing on an existing server, back up all data and record any important settings.
Remove the uninterruptible power supply (UPS) management cable from the server (even if it’s USB).
Upgrade the system BIOS to the latest version available.
Set the boot order in the BIOS to boot from the DVD before the hard disk.
Locate any mass storage drivers necessary for the system.
Configure the firewall or router as required.
