1.1.1 Booting Failure
When the WBS24 fails to boot up, it means that the flash memory with the program
is not functioning. All of the 5 LEDs, except the PWR, blink periodically at the same
time to inform the fault status. The flash memory might be broken when the process
of the WBS24 upgrade is interrupted, and the fault status can be removed using ‘the
upgrade using the network booting’ method.
