Spirent TestCenter: What is the operating temperature range for Spirent TestCenter chassis and appliances?

Answer

SPT-N4U, SPT-N11U, SPT-N12U Chassis
- 59° - 95° F (15° - 35° C)
- 10% - 80% relative humidity
DX3/PX3-QSFP-DD-8
- 41° - 86° F (5° - 30° C) ambient temperature
- 20% - 80% relative humidity
C1
- 0° - 30° C
C2
- 0° - 35° C
- 10% - 70% relative humidity (non-condensing)
C50
- 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:
- Normal :
  - Under normal temperature conditions temperature updates will be only sent when temperature difference is greater or equal to 5 degree.
- Warning:
  - 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.
- Critical:
  - 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.

For voltage thresholds refer to: FAQ20383 - Spirent TestCenter: Do we have any documentation about the voltage thresholds for the Power Supplies on STC chassis/appliances?
