Satun Comm Tech received a call from the NOC team to unplug ESCT2000 in order to clear the alarm as they inspect the fiber optic backplane. They found that a pin on the backplane is not in normal status. Please see attached for details. Please raise this case as a priority. If you require more information, please contact Satun Comm Tech or my team. The ESCT2000 card is still not re-pluged into chassis.
