7.3 Status signalling with LEDs and status messages
Built-In Test Equipment
The VSAT system has a Built-In Test Equipment (BITE) function in order to make fault
diagnostics easy during service and installation. The BITE test is performed during:
• Power On Self Test (POST), which is automatically performed each time the system is
powered on.
• Person Activated Self Test (PAST), which is initiated by starting a self test in the web
interface HELPDESK > Self test.
For details on error messages after a POST or a self test see Event list on page 7-2.
Means of signalling
The VSAT system provides various methods for signalling the system status.
LEDs on the front panel of the ACU are used to signal:
• Power on/off
• Logon
•Fail/Pass
See LEDs on the keypad of the ACU on the next page.
Display and web interface: In addition to general status messages, the display and the
built-in web interface of the ACU show any events (BITE error codes) with a short message
describing each error.
See System messages on page E-1.
