Alarms/Errors
920 FTBx-88000 Series
Alarms
FEC-LOAML (FEC-Loss Of Alignment Marker Lock) for Ethernet,
indicates that the location of the alignment marker payload sequence
for a given lane on the PMA service interface is not detected. Not
available with 100GE (1 Lane)/100GE (2 Lanes) interface.
FEC Degraded SER for Ethernet 50GE with FEC Degraded SER
enabled, indicates that a FEC degraded SER condition is detected.
FEC Exc. Skew (Excessive Skew) for Ethernet 50GE, indicates that the
skew exceeds the defined threshold.
Skew Alarm Threshold (bits) for Ethernet 50GE, allows setting the
threshold value that will be used to declare a skew alarm: 0 to 10550
(default is 4781). Default restore the default skew alarm threshold
value.
FED (FEC Excessive Degrade) for DCO when the FED check box is
selected, indicates that the BER is greater to the FED activate
threshold. The FED alarm is clear when the BER is below to the
deactivate threshold.
FlexE Group Down for FLexE, indicates that at least one PHY link of
the group is down or any of the FlexE group alarm is present.
FlexE Group Number Mismatch for FlexE PHYs/Instances, indicates
that the received FlexE group number is different of the one
configured. Not applicable when the group number is set to 0.
Frame Loss for Traffic Gen & Mon and eCPRI, indicates that a
sequence number is missing in the received frames.
Frequency indicates that the received signal frequency meets the
standard specifications (green) or not (red). Not available when using
an active copper SFP.
For Ethernet 100/1000M Electrical, 100M Optical, 1GE Optical,
10GE LAN/WAN, 25GE, or Fibre Channel
1X/2X/4X/8X/10X/16X/32X/64X interface/rate, the frequency range is ±
100 ppm. Not supported for 10M electrical.
