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:
Pointing LED Color and Status
G Solid green LED
R Solid red LED
B Blank or off LED
