13.4 Troubleshooting
Troubleshooting during line calibration
The following table lists options for troubleshooting for possible fault entries in the
calibration report:
Entry in the calibration
report
Content* Troubleshooting
1. Calibration status Line 1/2/1 CALIBRATED - FAIL
Loop 1_1/1_2
The last calibration of the line failed.
Check the other entries in the
calibration report for the line in order to
narrow down the cause.
Line 123 / 121 / 4 RE - CALIBRATION
Loop 1_1/1_2
The line must be recalibrated. The data
from the last calibration is no longer
valid as the line topology and/or
configuration parameters have been
changed in a way that affects the power
consumption of the line.
Recalibrate the line. You will find more
information on this in chapter 'Manual
line calibration [➙ 60]'.
3. Power consumption of
the line card
FDnet line card
Module 1/2 FAIL Itot = 590 mA
The power consumption of the line is
above the maximum load capacity of
the line card of 0.5 A.
Possible causes and troubleshooting:
● Too many line devices are
connected to the line card.
● The configured settings for the
'Sounder volume' and 'Beacon
intensity' properties are too high.
– Reduce the sound level of the
alarm sounder or the intensity of
the beacons on the affected line
card. You will find information on
the configuration of the sound
level of the alarm sounder or the
intensity of the beacons in
document A6V10210424.
FDnet line card
Module 1/2 UNKNOWN Itot = 469 mA
The entire power consumption of the
line card is unknown as either some of
the lines on the card have not been
calibrated or line calibration for certain
lines has been deactivated.
Troubleshooting:
● Check the calibration status of the
individual lines on the line card:
– Activate the calibration for the
individual lines in the system
configuration.
