EHAVIOR
When the terminal is powered up, it goes through a two-phase boot process. The first phase
loads a Minimum Boot ROM (MBR) module, which provides basic functionality, including self-test
and basic network connectivity.
When the self-test has completed with no failures detected, the MBR then proceeds to the
second phase, and loads the application module. This provides full terminal functionality.
If the applications module is not installed or is bad, a new application has to be installed. A bad
application could cause the terminal to stall in the second phase, or constantly reset. To prevent
this, the boot process can be stopped at the MBR phase, so that a new application can be
installed. This is achieved by holding down the audio button at the same time as the power
button is pressed.
If the audio button is accidentally pressed during power up, causing the boot process to stop at
the MBR phase, then simply power cycle the terminal. It will power-up through both phases of
the boot process.
If the terminal MBR module detects a failure during the self-test, it will stop the boot process and
indicate the source of the failure through the 6 LEDs used for pointing, as follow:
