In this chapter
This chapter describes the monitoring capabilities of the accelerators. The parameters described in the chapter can be monitored from the application through the API or by using the monitoring tool (see DN-0449).
Monitoring parameters can be divided into optical module parameters and accelerator parameters. They consist of both sensor parameters and state parameters.

Monitoring parameters
This table shows the most important accelerator parameters of which the NT accelerators provide monitoring.
Parameter | Mode of Operation |
---|---|
Link status | Ethernet link status per port |
PCB temperature | PCB temperature level and alarm |
FPGA temperature | FPGA temperature level and alarm Automatic over-temperature shutdown Note: Three FPGA temperature levels are significant:
Note: When the
LogToSystem parameter in the
ntservice.ini
file (see DN-0449) is set to
1, the warning messages are also logged in the system
log.
|
Time synchronization status | Status on accelerator time synchronization and loss of synchronization |
Fan speed | Speed of the cooling fan Note: An out-of-range fan speed event is written to the hardware
log if the fan rotates at a speed outside a specific range. The event can be
monitored from the application through the API.
For NT200A01-SCC the low limit is 5264 RPM and the high limit is 7450 RPM. For NT200C01-SCC, NT100E3-1-PTP and NT80E3-2-PTP the low limit is 4738 RPM and the high limit is 6566 RPM. For NT40A01-4×1, NT40E3-4-PTP and NT20E3-2-PTP the low limit is 4000 RPM and the high limit is 6000 RPM. |
