Save Power With the Eco-Friendly Feature
Eco-Friendly
You can conserve power by enabling the eco-friendly LED (Light Emitting Diode) feature
either by entering the
ecofriendly led command on page 8.13 or by pressing the
eco-friendly button on the front panel. This feature disables power to the port LEDs, but
not the power indicator LED. In the eco-friendly mode, one of the horizontal segments of
the seven segment display will glow permanently. If the device is a stack master, the upper
segment will glow; if the device is a stack member or a stand alone unit, the center
segment will glow.
When the eco-friendly LED feature is enabled, a change of port status will not affect the
display of the associated LED. When the eco-friendly feature is disabled and power is
returned to port LEDs, the LEDs will correctly show the current state of the ports.
In a stack environment, enabling the eco-friendly LED feature on the stack master will
apply the feature to every member of the stack.
The eco-friendly LED feature is disabled by default. To globally enable the feature for all
LED ports on the switch, either push the eco-switch button or enter the commands:
For an example of how to configure a trigger to enable the eco-friendly LED feature, see
“Turn Off Power to Port LEDs” on page 76.7 .
You can also conserve power by enabling the eco-friendly LPI (Low Power Idle) feature
with the
ecofriendly lpi command on page 8.14 . This feature reduces the power supplied
to the ports by the switch whenever the ports are idle and are connected to IEEE 802.3az
Energy Efficient Ethernet compliant host devices. All ports configured for LPI must support
LPI in hardware and must be configured to autonegotiate by default or by using the
speed and duplex commands as needed.
LPI is a feature of the IEEE 802.3az Energy Efficient Ethernet (EEE) standard. LPI lowers
power consumption of switch ports during periods of low link utilization when connected
to IEEE 802.3az compliant host devices. If no data is sent then the switch port can enter a
sleep state, called Low Power Idle (LPI), to conserve power used by the switch.
The eco-friendly LPI (Low Power Idle) feature is disabled by default. To enable the feature
for a switch port, or for a range of switch ports in the example below, enter the commands:
For an example of how to configure a trigger to enable the eco-friendly LPI feature, see
“Reduce Power Supplied to Ports” on page 76.9 .
