The DGS-1500-28 implements D-Link Green™ 3.0 Technology, which includes a power saving mode, 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.
