Do not disable tamper detection unless asked to do so by Support.
After reseting the unit to a factory state, you require a quorum of the ACS to restore the
key data and reconnect the nShield Connect to the network. If you chose to disable the
tamper protection circuitry when you reset the nShield Connect to a factory state, a
cautionary warning is displayed prior to the request for card authorization. For
information about re-enabling disabled tamper detection functionality, see
tamper detection and response
8.4.1.2. nShield Connect lid is open
If the nShield Connect is powered, a tamper event has occurred, and the lid is open, the
following message is displayed on screen:
** TAMPER DETECTED **
Unit lid is open
Replace lid or disable
tamper detection
DISABLE
An open lid indicates that the physical security of the unit is compromised. You may
want to examine your unit for other physical signs of tampering - see
checks. Do not attempt to put the unit back into operation.
The date and time of the tamper event are recorded in the log files (see Logging,
debugging, and diagnostics of the nShield Connect User Guide). If the tamper event
occurred
• During transit from Entrust, contact Entrust nShield Support
• After installation, refer to your security policies and procedures.
If you choose to replace the lid of the nShield Connect, the onscreen message changes
to the tamper alert message that is given when the lid is closed. Closing the lid provides
you with the option to reset the unit to a factory state without disabling tamper
detection functionality. If the lid remains open, all button presses other than those made
using the right-hand navigation button are ignored. Pressing the right-hand navigation
button disables tamper responsiveness and resets the nShield Connect to a factory state.
