D-Link Green Technology

Power Saving: Enabled by default, save
energy in 6 ways:
- Power Saving by Link Status: Drastically
save power when the switch port link is
down. For example, no PC connection or
the connected PC is powered off.
- Power Saving by Cable Length: Detects
the length of connected RJ-45 cables and
adjusts power usage accordingly without
affecting performance. Once the RJ-45
connection is less than 20 meters, the
switch will reduce the power instead of full
power, which is only needed for 100 meters
cables.
- Power Saving by LED Shut-Off: Posered
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
fingures since main chipsets (both MAC and
PHY) are disabled for all ports, and energy
required to power the CPU is minimal.
