Line in This connector accepts audio signals into the computer sound system from external devices, such as the line output from a stereo, television, or a musical instrument. One line-in connector is on the rear of the computer. Line out This connector sends audio signals from the computer to external devices, such as speakers with built-in amplifiers, headphones, multimedia keyboards, or the audio line-in jack on a stereo system. Line-out connectors are on both the front and the rear of the computer. Microphone Use this connector to connect a microphone to the computer when you want to record voice or other sounds on the hard disk. With a microphone attached to the computer, you can also use speech-recognition software. One microphone connector is on the front of the computer. Using security features To deter unauthorized use of the computer, you can use anti-intrusion features and other security features that are provided with the computer. Anti-intrusion features IBM anti-intrusion features help protect against the theft of computer components, such as the microprocessor, system memory modules, or hard disk drives. You can set the chassis-intrusion detector switch inside the computer to alert the network administrator each time the computer cover is removed. For more information about setting the chassis-intrusion alert, see Chapter 3, "Configuring the computer," on page 21. Component protection Each component in the computer has a serial number that you can register with a security company. You can register the components individually, or you can register the entire computer. By registering computer components, you can improve the chances of identifying the components if they are ever stolen and recovered. For more information about component registration, see http://www.ibm.com/support/. Data protection You can lose data from the hard disk for a variety of reasons. Security violations, viruses, or hard disk drive failures can all contribute to data loss. To help protect against the loss of valuable information, IBM has incorporated the following data-saving features in the computer: v SMART hard disk drive The computer comes with a self-monitoring and reporting technology (SMART) hard disk drive that is enabled to report potential hard disk failures. If an error is detected, a Desktop Management Interface (DMI) compliant warning message is sent to the monitor screen and, if the computer is part of a network, to an administrator console. When an error is detected, the data on the hard disk can be backed up and the drive replaced. v Virus protection The computer has built-in virus protection that can be enabled through the IBM Configuration/Setup Utility program. Norton AntiVirus for IBM is available on the hard disk. 16 IBM IntelliStation Z Pro Type 9228: User's Guide
