is relevant to the thermal performance of the PES16NT2 switch.
IDT 89HPES16NT2 Data Sheet
Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 14.
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in
All power measurements assume that the part is mounted on a 10 layer printed circuit board with 0 LFM airflow.
