Description
The eight upconverters
installed in the NSG are
not the same type. The
NSG checks the
upconverters during
boot up and sends this
alarm if it detects that
there are different
types of upconverters.
All eight upconverters
must be the same type
for the NSG to function
properly.
This alarm is sent when
an upconverter sends
four critical alarms
within a 24-hour
period. The affected
upconverter is
automatically shut
down when this alarm
occurs.
The following alarms
are considered critical
alarms:
Internal
Communication
Failure
Power Failure
PLL1 Failure
PLL2 Failure
Solution
Call Customer Support.
Call Customer Support
Reboot the NSG to clear
the alarm, but it is likely
to occur again.
