5 CONFIGURATION & CONTROL

5.1 WhereLAN III Self Boot

Upon power up, WhereLAN III executes a self-boot process. The boot

process takes between 45 to 60 seconds. If a fault occurs during the boot

process, the unit may reset and restart the boot process. During that process,

the four LEDs blink in a sequence to indicate the current stage of the power

up boot process. The LED Process is as follows after initial power is applied.

• 1 LED (Power): The Boot Loader is loading the Kernel.

• 4 LED’s : The Kernel is initialized and is loading the applications,

JFFS2 and CRAM File system

• 1 LED (Power): The Application is loading the FPGA’s and DSP’s

• 2 LED’s (Power and Tag Reception): The unit is initializing the

FPGA’s and DSP’s.

• 1 LED (Power): Unit is booted and ready for operations.
