Mobile Gateway S20

Status displays on the Sea-Of-Sims (SOS)
The SOS status display allows you to follow the individual diagnosis steps during the
booting phase on commencing operational mode. You can also see when the system is in
default mode due to missing configurations. Thus, you can recognize all possible stages of
operation by observing the light emitting diodes on the SOS. (see also Picture 38)
Upon connecting the NovaTec
S20 to the main supply, the system undertakes a processor test
followed by a RAM- and firmware test. When there is a valid configuration, the system then
moves into operational mode. In cases where there is no configuration, the system starts up in
the default configuration (Power-LED is off). This means that only the first two BRA interfaces
and the first PRA interface of the SOS is being activated and the Ethernet-Interface works with
the last known IP-Adress. Has the Modul set into default mode by using the Reset-Switch or
Trace-Info-Client, then the SOS starts also in default mode but with the IP-Adress
192.168.127.254
.
If the NovaTec
S20 starts in the default configuration, a valid configuration must be transmitted
through downloading. Downloading can be undertaken via the IP interface. After downloading
is completed, the system resets itself and starts up using the previously transmitted configuration.
At the first commissioning, the system commences with a test configuration that is used by the
supplier as a quality control check. For this reason it is imperative that the download procedure
is undertaken
.
If a modified configuration is being transmitted during the running operation, the level of
changes will determine whether or not the system undertakes a restart. As a precaution,
you should undertake the download procedure at a time that avoids high levels of data
transmission activity because connections will be interrupted should the system require a
restart.
After the boot process the status of each individual line interface of SOS is displayed by
the status of the LED. If the layer one of an interface is activated, the appropriate LED
turns steady on. In case the layer one of the interface is deactivated so the LED turns off.
The SOS contains two plug in space for one daughter board each and an ethernet interface.
The LED status of the SOS is dependent of the daughter board placed and configured into
it. The following table shows the status and the meaning of the LEDs of the SOS in normal
mode (non default mode):
