Spirent TestCenter: What is the operating temperature range for Spirent TestCenter chassis and appliances?
SPT-N4U, SPT-N11U, SPT-N12U Chassis
59° - 95° F (15° - 35° C)
10% - 80% relative humidity
41° - 86° F (5° - 30° C) ambient temperature
20% - 80% relative humidity
0° - 30° C
0° - 35° C
10% - 70% relative humidity (non-condensing)
5° – 35° C
10% – 90% relative humidity (non-condensing)
More information can be found in the “Spirent TestCenter Hardware Reference” documentation and attached datasheets.
Note: For chassis/appliances that have temperature sensors, the inlet temperature sensors are assumed to be 5° C higher than the ambient temperature,
CPU and FPGA temperature
There is also temperatures related to the modules themselves.
The firmware support for reading these temps is not available on every hw platform.
It should not matter what mode or speed for a multi-speed module.
This new temp feature is a physical check for potential damaging environment (think hot labs) for the modules.
Temperature Thresholds: (These are the only ranges defined and will be applied to all modules.)
Critical FPGA Temperature: 115.0
Warning FPGA Temperature: 100.0
Critical CPU Temperature: 100.0
Warning CPU temperature: 90.0
Temperature Module details are as below:
Under normal temperature conditions temperature updates will be only sent when temperature difference is greater or equal to 5 degree.
No Action Initiated. Pop-up message appears on the STC as well as logged.
“For Chassis <chassis-name>, temperature of the card <n> has reached the Warning level.
Test module (TM) sends OUTAGE message 3-degree Centigrade before reaching to h/w defined Critical Threshold.
Chassis VM system manager daemon handles this message and notifies BLL to cleanup TM book keeping.
BLL handles cleanup message and informs chassis.
Chassis VM cleans up after receiving response, if BLL response doesn’t come it waits till actual critical temperature and forcefully brings down the system.
