Chapter 8: Verifying the Hardware Operations of the Chassis

Using the LEDs to Verify the Chassis
After powering on the chassis for the first time and waiting a minimum of 
two minutes for the line and controller cards to complete the initialization 
process, check the operational status of the various hardware 
components by examining the LEDs, as explained in this procedure:
1. Check the LEDs on the power supplies:
AT-SBxPWRSYS1 and AT-SBxPWRPOE1 AC Power Supplies: 
The power supplies are operating properly when the AC and DC 
LEDs are solid green and Fault LEDs are off. If there is a problem 
with a power supply, refer to “AT-SBxPWRSYS1 and AT-
SBxPWRPOE1 AC Power Supplies” on page 190 for 
troubleshooting suggestions.
AT-SBxPWRSYS1 DC Power Supply: The power supply is 
operating properly when the DC IN and DC OUT LEDs are solid 
green and the Fault LED is off. If there is a problem, refer to “AT-
SBxPWRSYS1 DC Power Supply” on page 191
 for 
troubleshooting suggestions.
2. Check the Power LED on the AT-SBxFAN06 module. The module is 
operating normally when the LED is solid green. If the LED is off, the 
fan module has a problem or failed. Power off the chassis and contact 
your Allied Telesis representative for assistance. Do not operate the 
chassis without a fully operational fan unit.
3. If the chassis has one controller card, check the CFC LED on the card. 
It should be solid green. If the LED is flashing green, the card is still 
initializing its AlliedWare Plus Operating System. Wait another minute 
and check the LED again. If the LED is still flashing green, the card 
may have encountered a problem that prevents it from completing the 
initialization process. Power off the chassis and replace the controller 
card.
Note
If all the LEDs on the controller card are off, they may have been 
turned off. Try pressing the eco-friendly button on the card to turn 
them on.
4. If the chassis has two controller cards, check the CFC LEDs on both 
cards. The cards are operating correctly when the LEDs are solid 
green on one card and solid amber on the other. If both LEDs are 
flashing green, the controller cards are still completing the initialization 
process. If the LEDs do not change to solid green and amber after 
another minute, the cards may have encountered a problem that is
