Setting the diskette write-protect switch The diskette write-protect switch controls whether you can write information to a diskette using a diskette drive. The ability to prevent writing to a diskette is particularly useful if you are concerned about the security of information that can be obtained through a network. Note: This switch does not affect the ability to read information from a diskette. Before you begin: Read "Electrical safety" on page 70 and "Handling static-sensitive devices" on page 71. Turn off the server and all other connected devices. Disconnect all external cables attached to the server; then, remove the server cover (see "Preparing to add options" on page 73). 1. Locate the configuration switches (also known as rocker switches) on the system board. For more information, refer to the label inside the server, or see "System Board Illustration" on page 253. 2. For normal diskette operation or for read-only diskette operation, set switch 8 as shown in the following illustration. It might be helpful to use the end of a small screwdriver to set the switch. Attention: The following illustration is for reference only. Before you change the settings for switch 8, be sure that you check the orientation of your server system board to correctly identify the switch number locations. If you change the settings for the wrong switches, you might seriously damage server components or options. 268 Netfinity 3000 User's Handbook
