D-Link DGS-1500-52 SmartPro 48 Port Gigabit Ethernet Switch with 4 SFP Slots

The D-Link DGS-1500-52 implements Green 3.0 Technology, which includes a power saving mode, smart fan, reduced heat dissipation and cable length detection. The power-saving features include being able to schedule when to turn off LEDs and ports and when to make the switch enter hibernation mode. It detects the length of connected cables to automatically adjust power usage by saving energy on shorter cable connections. It also supports power saving by link status, which reduces power consumption by automatically toggling ports without a link to sleep mode. The DGS-1500-52 features built-in smart fans that contribute to continuous, reliable and eco-friendly operation of the switch. Using a thermal sensor that can detect temperature change, the fans can react accordingly by utilizing different fan speeds for different temperatures.
