3.3.8 LED Fault indication
In addition to display port and traffic status, the LED front panel will display fault information if
the switch is managed (U/R200 series). The LED fault indications are as follows:
•
HDX LED will blink in case of a FRNT v0 error. I.e. the FRNT v0 ring is not intact.
The focal point or a member switch will indicate that one or both of its FRNT0 ring
ports is not working (link is OFF, or no FRNT v0 packets are received. The HDX LED
will also blink on the FRNT v0 focal point even if its FRNT v0 ports is working if the
FRNT v0 ring is not intact. Relevant in case FRNT v0 (FRNT ring) is enabled in the IP
configuration tool.
•
FDX LED will blink in case of a port alarm. Relevant in case port alarm is enabled in
the IP configuration tool.
•
100 LED will blink in case of no PPS signal or no NMEA reports from the GPS
receiver is received on the GPS interface. Relevant when time synchronization and
external time base are enabled in the IP configuration tool. The 100 LED will also
blink in case the SNTP client is out of synchronization, relevant in case SNTP client is
selected in the IP configuration tool.
•
10 LED will blink in case of an FRNT v1 error. I.e. no communication to remote
FRNT v0 ring via the FRNT v1 enabled port (either primary or secondary FRNT v1
port). Relevant in case FRNT v1 is enabled in the IP configuration tool.
When the fault contact is energised the front panel display will also mimic this status by
strobing one or more the above LEDs. When the fault(s) is cleared the LEDs will automatically
be extinguished.
