| Standard | According to UTE C 80-810 |
Electrical rating
This table shows the power consumption for an NT400D11-NEBS SmartNIC including 2 pluggable modules.
| Port Speed | Power consumption [in W] |
|---|---|
| NT400D11-NEBS 2 × 100 Gbit/s | 75 |
Power is measured with capture of a stream with 80% load of 300-byte frames. A sustaining load of 80% with 300-byte frames is representative for maximum real-life scenario. The actual power consumption depends on the FPGA software payload.
The SmartNIC is Class III equipment for supply by SELV circuits only.
