NTRODUCTION

The Switch 4210 26-port, 18-port, and 9-port PWR models provide an
over-temperature protection mechanism. When the internal temperature exceeds
65

°C (149

F), they will stop providing power from all ports. When the temperature

is below 60

°C (140

F), they will continue to provide power from all ports.
