4.6.18 Alarms 3718 - 3804 SNE I/O
GCP Alarm Descriptions 3718 - 3804 SNE I/O
The following tables list the alarm number (#), type (+ information, ? warning, ! error) alarm
text, description, and actions.
# Text Description Action
3718 ! FPGA Error Full on %4 SNECON PICs: The FPGA queue to the
NS486 was full and a packet could not
be sent. A best attempt is made to con‐
tinue but one or more packets were lost.
Reset the SNECON.
Replace the SNECON.
3719 ? FPGA error reset_W on %4 SNECON PICs: A FPGA reset was de‐
tected during a packet write from the PIC.
The packet and any packet still in the
FPGA queues were lost.
Reset the SNECON.
Replace the SNECON.
3720 ? FPGA error reset_R on %4 SNECON PICs: A FPGA reset was de‐
tected during a packet read by the PIC.
The packet and any packet still in the
FPGA queues were lost.
Reset the SNECON.
Replace the SNECON.
3721 ? FPGA error_W on %4 SNECON PICs: An error was detected
while writing the packet header or data
to the FPGA. A best attempt is made to
continue but one or more packets may
be lost.
Reset the SNECON.
Replace the SNECON.
3722 ? FPGA error_R on %4 SNECON PICs: An error was detected
when reading the packet header or data
from the FPGA. A best attempt is made
to continue but one or more packets may
be lost.
Reset the SNECON.
Replace the SNECON.
3725 ! Error SCL on %4 SNECON PICs: An abnormal situation
was detected on the I2C 'Serial Clock'
line. This is an indication that the WDB is
broken, a cable harness is broken or one
board connected to the I2C bus is mal‐
functioning, pulling the I2C data signal to
a logical low.
Contact Customer Support.
3726 ! Error SDA on %4 SNECON PICs: An abnormal situation
was detected on the I2C 'Serial Data'
line. This is an indication that the WDB is
broken, a cable harness is broken or one
board connected to the I2C bus is mal‐
functioning, pulling the I2C data signal to
a logical low.
Contact Customer Support.
3727 ! I2C will not align on %4 SNECON PICs: I2C communication er‐
ror.
Contact Customer Support.
3728 ? I2C msg not allowed on %4 SNECON PICs: A packet containing an
I2C message was received by the PIC
(from the NS486 through the FPGA) at a
time when it is not allowed but after a val‐
id configuration message was received.
The message was discarded.
Reset the SNECON.
Reload the OS for the SNECON.
Replace the SNECON.
