    TITLE:  Chassis Intrusion, Bravo MS/MS-T

    ISSUE

       When the Chassis Intrusion feature is ENABLED in System Setup, if
       the cover was removed, the Bravo MS or MS-T system may not warn
       the user that an intrusion was detected.

       This issue affects all Bravo MS and MS-T systems.

    BACKGROUND

       N/A

    ACTION

       Customers concerned about chassis intrusion have the added option
       of locking their computer system with the included lock eyelet
       which is located on the back of their system.

    NOTES

       The system is operating as designed.

       Due to the differences in ambient lighting and the computer's
       physical locations, the Chassis Intrusion feature may not detect
       a Mini-Tower that has had its cover removed.

       The Bravo MS/MS-T uses a photocell to detect light hitting the
       sensor. Because one cannot determine the actual amount of light
       given a particular customer environment, there may be a
       difference in the way a desktop reports an intrusion as compared
       to a mini-tower.
