{{DrawBoxNote|content=If you have previously installed and configured a server and are reinstalling the software, please be aware that you should use the procedure described in section 5.3. Upgrading From A Previous Version in order to preserve your existing configuration and data. Simply performing a new installation will erase all previously existing user accounts, user directories, i-bay contents and web site and configuration parameters. If you have not already done so, you may wish to back up the contents of your server onto one of your desktop computers. You can do so easily by selecting "Backup or restore" from the server manager, as explained in chapter 10.1.||

The SME Server comes by default with RAID1 disk mirroring if you install one or two drives.  The server is configured to accept one drive and will function properly.  You can verify the RAID1 status from the console. If you later wish to add a second drive, just add it and instruct the server via the console to create the mirror.  It will take some time to build so do it during scheduled maintenance.  They can be either SCSI or IDE drives.

If you are going to use hardware mirroring, you should NOT choose Install - Dual hard disk with software RAID-1 mirroring during the installation process described in section 5.4. Installing the Software. (Doing so will enable software mirroring.) Instead, you should do a regular installation of the software.

The password will also be examined to determine how strong it is from a security point-of-view. If it is found to be weak (for instance, a dictionary word), you will see an additional screen asking if you really want to use this password. You will have the option to go back and change to a stronger password or to continue using the weaker password.

If you have a static IP address and your ISP does not offer DHCP or PPPoE, then your ISP will give you the static IP address, subnet mask (or netmask), and the gateway IP address of the device that your server should connect to in order to communicate with the Internet.

PPPoE is the Point-to-Point Protocol over Ethernet . Essentially, it is an implementation of the popular PPP protocol used for dialup connections - only configured to run over an Ethernet connection. Many ISPs that provide ADSL connections use PPPoE as the method of connecting their customers to the Internet over ADSL.}}

This last item may be of special interest. As shown in the screen below, you can configure what type of policy you wish to have in place during typical work hours. If you are in a small office and wish to share your phone line between your computer and phone or fax, you may wish to minimize the time you are online. This is also true if your ISP charges a fee on a per-minute basis. On the other hand, if you have a separate phone line or unlimited time with your ISP, you might want to have long connection times or a continuous connection.
