• During power-up.
• When a new software version is loaded that includes an update to the FPGA.
• When a RAC, DAC or AUX is installed in a powered Node.
• Depending on the plug-in, FPGA loading may occur during a reconfiguration
of Node backplane and/or RAC/DAC capacity.
RAM Failure
The RAM test has failed. This is a warning alarm.
Probable Cause
Equipment or process malfunction.
Recommended Actions
1. Check for other alarms to determine how critical the test failure is. Depending
on the malfunction, the node may otherwise operate satisfactorily.
2. Reboot (power off, pause, power on).
3. If the alarm remains, replace the NCC/IDU.
Additional Information
RAM function is checked during power-up and software reloads.
Flash Card Failure
Loss of communications with the flash card. This is a warning alarm.
Probable Cause
Flash card or process malfunction.
Recommended Actions
Reboot (power off, pause, power on). If the alarm remains, first replace the NCC/
IDU, reboot, and if the alarm persists, the flashcard.
Additional Information
The flash card memory function is checked during power-up and software
reloads.
Loss of communications means the configuration for the node cannot be
accessed.
Replacing a flashcard requires complete re-configuration of the Node/Terminal.
