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.
Related Standards The 3Com Switch 4210 Family is designed to the following standards:
