20 CHAPTER 1: PRODUCT INTRODUCTION Table 11 Technical specifications for the Switch 4210 PWR models Model Switch 4210 26-port PWR Switch 4210 18-port PWR Switch 4210 9-port PWR Power system Switch 4210s 26-port PWR support AC input and DC input. Switch 4210 18-port PWR/Switch 4210s 9-port PWR support only AC input. AC input: ■ Rated voltage range: 100 VAC to 240 VAC, 50 Hz/60 Hz ■ Input voltage range: 90 VAC to 264 VAC, 47 Hz to 63 Hz DC input: ■ Rated voltage range: -52 VDC to -56 VDC All ports serve as PoE ports System AC input: 465 W power consumption DC input: 400 W (full load) 160 W 95 W PoE power 15.4 W × 24 maximum 15.4 W × 8 15.4 W × 4 Number of fans 4 2 2 Operating temperature 0°C to 45°C (30°F to 113°F) Relative humidity (non-condensing) 10% to 90% n 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.
