8.4 Status signalling with LEDs and status messages
8.4.1 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 installation and service. 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 8-4.
8.4.2 Means of signalling
The SAILOR 100 GX 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
• Antenna POST error
• SAFE MODE (plus information about the specific error, see System messages on
page D-1).
8.4.3 LEDs of the ADU modules
Each ADU module has two LEDs: a Power and a Service LED.
For a list of modules see Removal and replacement of ADU modules on page 8-18.
