Chapter 1: Overview

You use the eco-friendly button on the control card to turn the LEDs on or 
off and test the LEDs. You may turn off the LEDs when you are not using 
them to monitor the control and Ethernet line cards, to conserve electricity. 
When the LEDs are off, the overall power consumption of the chassis is 
slightly reduced, approximately 3 watts in a system with 240 active copper 
ports.

The button controls all of the port LEDs on the Ethernet line cards and all 
of the LEDs on the control 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.

You may use the Reset button to reset either the control card or all of the 
cards in the chassis. The action depends on the number of AT-SBx31CFC 
Central Fabric Controller cards in the chassis and, if the chassis has two 
control cards, whether you press the button on the active or inactive 
master card.

The possible actions are described here:



If the chassis has only one control card, pressing the Reset button 
resets the control card and all of the Ethernet line cards in the 
chassis. You may perform this function if the chassis and line 
cards are experiencing a problem.

0 to 11

Solid Amber

Indicates that the card is in an off-line, 
reset, or disabled state. You may remove 
the card from the chassis when it is in this 
state. If the LED is solid amber for an 
Ethernet line card, it may indicate that the 
card cannot boot up because the control 
card does not have the appropriate load file 
and needs to be updated to the most recent 
release of management software.

Flashing Amber

Indicates that the card is reporting a fault 
condition. Use the management commands 
to determine the specific problem.
