ibm anti-intrusion features help protect against the theft of computer components,such as the microprocessor, system memory modules, or disk drives.

    a cover lock is built into your computer to prevent the cover from being removed. two identical keys for the cover lock are also supplied. a tag attached to the keys has the key serial number and the address of the key manufacturer.

    record the key-code number along with the manufacturer address and phone number in the space provided in "appendix c. computer records". you will need the key code when ordering replacement keys. you must order replacement keys from the key manufacturer because locksmiths are not authorized to duplicate cover-lock keys.

    if enabled, the chassis-intrusion detector switch inside the computer alerts the net work system administrator each time the computer cover is removed. this detector is enabled after you set a supervisor password in the bios setup utility program. when this feature is enabled and the cover is removed, a 176 post error message displays on the computer screen the next time the computer is turned on. you must type the correct supervisor password to start up the computer. for information on setting passwords, see setting security passwords in access ibm. if your computer uses the alert on lan feature, and your network administrator uses intel landesk desktop manager or ibm lanclient manager, the network administrator console is notified that the computer cover has been removed. for more information, see "alert on lan" on page 19 and contact your network administrator.
