D-Link Green??? V3.0 Technology


The DGS-1500-28P implements D-Link 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-
1500-28P 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.



Advanced Features


The DGS-1500-28P boasts advanced features such as Virtual Stacking and Static
Routing. Virtual Stacking reduces the number of IP addresses needed on a network
by configuring up to 32 devices to appear as a single unit with one IP address. This
simplifies network management for small workgroups and allows for switches to be
added without special cabling. In static routing, IP routes are manually entered into a
routing table. This function allows for communication between different user groups in
different VLAN segments in a network. The DGS-1500-28P can handle the inter-VLAN
routing, making the network run faster and more efficiently. This allows the network
router to handle external traffic routing only.
