Description
NGDdx 1 Fail (Expansion shelf 1
communication link failure)
NGDdx 2 Fail (Expansion shelf 2
communication link failure)
NGDdx 3 Fail (Expansion shelf 3
communication link failure)
GLD address 1 is failed.
GLD address 2 is failed.
One or more GLD units addressed 3
through 12 may be failed.
Chan. Port has not forwarded any traffic
in the time specified by the Channel
Timeout Timer. The channel feature
forwards data between two ports so the
NG may be used to analyze serial
traffic using CHAN filter debug.
The Craft Timeout Timer has not been
reset in the specified time. This feature
is designed so other machines may
keep the TTY link active. If the TTY
interface becomes unavailable to the
machine, then the Craft Timeout alarm
is set.
The Event Que is filled with more than
500 uncollected events.

Solution
Under Ports > Options, verify the
number of configured NGDdx units.
Use EXP filter debug and port LEDs to
help diagnose the problem. Use DB9M
to DB9M with null crossover for cabling.
Verify the DIP addressing on the back
of the NGDdx unit.
Connect just GLD unit 1 and attempt to
poll. Verify GLD is connected to data
port 8 and the hardware is RS485, not
RS232.
Verify the GLD unit addressing, and
test GLD units individually on the GLD
communication bus.
Reduce the number of connected GLD
units to determine which unit may be
causing the link to fail.
Change the data port type to OFF, or
set the Channel Timer to a different
setting.
Change the Craft Timeout Timer to 0 to
disable the feature.
Enable DCP timestamp polling on the
master so events are collected, or
reboot the system to clear the alarm.
