Excellent RPS Design: When working with the new RPS(DPS-700), DGS-1500-28P supports expansion mode. –Expansion Mode: RPS acts as a load sharing power; PoE power budget expands to 740W. IEEE 802.3at PoE+: DGS-1500-28P: All copper ports support PoE+ and supply up to 30W per port. Product Overview - Advanced Hardware Design

6. Silence and High Reliability: Fan-less Technology: –DGS-1500-20/28 emits less heat and noise than the standard switch, making it suitable for environments like office or other place requiring low acoustics. Smart Fan: –DGS-1500-28P/52 come with a thermal sensor that can detect the change of environmental temperature. Hence, the fans can react accordingly with different fan speeds and acoustics can be minimized. Product Overview - Advanced Hardware Design

7. D-Link Green 3.0: D-Link provides more Green technology to save your money. –Power saving by Time-based PoE: PoE ports can be turned on/off by port or system through schedule –Power saving by LED Shut-Off: Powered LEDs can be turned on/off by port or system through schedule –Power saving by Port Shut-Off: Each port on the system can be turned on/off by schedule. –Power saving by Port Standby: Each port on the system enters sleep state by schedule. –Power saving by System Hibernation: System enters hibernation by schedule. In this mode, switches get most power-saving figures since main chipsets (both MAC and PHY) are disabled for all ports, and energy required to power the CPU is minimal. –IEEE 802.3az EEE –Power saving by Link Status. –Power saving by Cable Length.
