POWER-ON SELF-TESTSATELLITE TERMINAL BOOT BEHAVIORWhen the terminal is powered up, it goes through a two-phase boot process. The first phaseloads a Minimum Boot ROM (MBR) module, which provides basic functionality, including self-testand basic network connectivity.When the self-test has completed with no failures detected, the MBR then proceeds to thesecond 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 badapplication could cause the terminal to stall in the second phase, or constantly reset. To preventthis, the boot process can be stopped at the MBR phase, so that a new application can beinstalled. This is achieved by holding down the audio button at the same time as the powerbutton is pressed.If the audio button is accidentally pressed during power up, causing the boot process to stop atthe MBR phase, then simply power cycle the terminal. It will power-up through both phases ofthe boot process.If the terminal MBR module detects a failure during the self-test, it will stop the boot process andindicate the source of the failure through the 6 LEDs used for pointing, as follow:Pointing LED Color and StatusGRBBGBRSolid green LEDSolid red LEDBlank or off LEDBlinking green LEDBlinking red LED1 2 3 4 5 6 Description of Failure ActionR B B B B B The main processor has failed to start Note 1G BR BR B B B The main processor has detected a fault in itsmemoryNote 1G BR BG BR B B The terminal SW is not properly installed Note 2G BR BG BG BR B The terminal SW is not properly installed Note 2G G BR BR B B The main processor has detected a fault in theEthernet interfaceG G BR BG BR B The main processor has detected a fault in theUSB interfaceNote 1Note 1G G BR BG BG BR The main processor has detected a fault on the Note 1Hughes 9201 BGAN Terminal User's Guide 2.2 93
