Status signalling with LEDs and status messages
9.3 Status signalling with LEDs and
status messages
9.3.1 Overview
9.3.1.1 Built-In Test Equipment
The ADU and the ACU have 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 9-3.
9.3.1.2 Means of signalling
The SAILOR 900 VSAT 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
The built-in web interface of the ACU shows any events (BITE error
codes) with a short message describing each error. This is also
displayed in the ACU.
In an error situation, one of the following system status messages
may be shown:
• ACU POST error
• ADU POST error
• SAFE MODE (plus information about the specific error, see System
messages on page G-1).
