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 AT-SBxPWRSYS1 and AT-SBxPWRPOE1
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 Power Supplies” on page 148 for troubleshooting
suggestions.
2. Check the Power LED on the AT-SBxFAN12 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 management software. 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
prevents them from completing the initialization process. Power off the
chassis and replace the cards.
5. To check the status of the Ethernet line cards, inspect the SBx
Linecard Status LEDs on the controller card. (If the chassis has two
controller cards, you may use the LEDs on either card.) A line card is
operating normally when it corresponding LED is solid green. The LED
flashes green as the card initializes its management software. If an
