NTC314AAE6 Media Gateway utility card
Important:
Removing the utility card for maintenance and then re-inserting it could result in a PFTS for
a period of milliseconds. This may cause a power fail transfer box to activate if you have not
disabled the card for maintenance service. You can remove the utility card without causing
loss of service, however it can cause a loss of ringing and message waiting. Removing the
utility card does not prevent an outgoing call, but prevents an incoming analog call.
Figure 200: NTC314AAE6 utility card
The utility card supports all international requirements for message waiting voltages as well as
ringing requirements. A dip switch is required on this card for various country requirements.
The utility card is also hot-pluggable, thus you can connect it with the system turned on.
There are five tri-colour LEDs on the faceplate. Three LEDs are for the blowers and indicate
green as normal, orange as running at full speed, and red as a failure. The other two LEDs
provide the status of the power supplies with green being normal and red or extinguished
indicating a partial or full failure. The power supply LEDs are directly controlled by the power
supplies while the blower LEDs are controlled by controller circuitry on the blower modules.
The following tables describe the LED states for the power supply, blowers, and ringing and
message waiting.
