Chapter 3: Overview of the AT-SBx31CFC960 Controller Fabric Card
eco-friendly Button
The eco-friendly button on the controller card is used to turn the LEDs on
or off and test the LEDs. You may turn off the LEDs to conserve electricity
when you are not using them to monitor the controller and Ethernet line
cards. When the LEDs are off, the overall power consumption of the
chassis is slightly reduced, approximately 2 watts in a system with 120
active copper ports.
The button controls the LEDs on the ports on the Ethernet line cards and
the LEDs on the controller card, except for the M/S (Master/Slave) LED,
which is always on. The button does not control the LEDs on the fan
module and the power supply systems.
The eco-friendly button is also used to test the LEDs. The LEDs perform a
lamp test, flashing in alternating colors for three seconds, when you press
the button.
