10.1.2 Status LED
The blue Status LED indicates the operational status of the module.
Status LED Description
Off.
Status: Power off or Standby mode
There is either no power supply to the module or the
module is in Standby mode. If you suspect that there is
no power supply, check that the module is properly
connected and switched on.
If you believe the module’s power supply unit has
failed, contact Support.
On, occasionally blinks off.
Status: Operational mode
The module is in Operational mode and accepting
commands. The more frequently the Status LED blinks
off, the greater the load on the module.
Flashes two short pulses, followed by a
short pause.
Status: Initialization mode
Existing Security World data on the module has been
erased.
The module is automatically placed in Initialization
mode after a Security World is created. For more
information, see the
nShield Connect User Guide
.
Flashes two long pulses followed by a
pause.
Status: Maintenance mode
Used for reprogramming the module with new
firmware.
The module only goes into Maintenance mode during
a software upgrade.
Flashes SOS, the Morse code distress
code (three short pulses, three long
pulses, three short pulses).
After flashing SOS, the Status LED
flashes a Morse code letter which
identifies the error.
Status: Error mode
If the module encounters an unrecoverable error, it
enters Error mode. In Error mode, the module does not
respond to commands and does not write data to the
bus.
For internal security modules running firmware 2.61.2
and above, the error code is also reported by the
enquiry utility in the hardware status field of the
Module and under hardware errors in the hardserver
log.
If a command does not complete successfully, the
module normally writes an error message to the log file
and continues to accept further commands. It does not
enter Error mode.
For information about error codes, see the User
Guide.
