AT-SBx31CFC960 Controller Fabric Card
240
If the chassis has one controller card and it fails, all network operations
stop. The Ethernet line cards do not forward network traffic until the
controller card is replaced.
If the chassis has two controller cards and one fails, the Ethernet line
cards continue to forward traffic, but the traffic bandwidth of each line card
slot is reduced from 40 to 20Gbps, which may result in slower network
operations.
The M/S LED on the controller card in a chassis that has only one
controller card should be solid green to indicate normal operations. If the
LED is flashing amber, wait one or two minutes for the card to complete
the initialization process and check the LED again. If it has not changed to
solid green, the card may have encountered a problem completing the
initialization process. To resolve the problem, you might try moving the
controller card to the other controller card slot, slot 4 or 5, to see if it works
in the new slot, or connecting a terminal or PC with a terminal emulator
program to the Console RS232 port to watch for error messages.
If the chassis has two controller cards, the M/S LEDs should be solid
green on one card and solid or flashing amber on the other card. If both
LEDs are flashing amber, wait one or two minutes for the cards to
complete the initialization process and check the LEDs again. If both LEDs
are still flashing amber, the cards may have encountered a problem
completing the initialization process. Try replacing the cards.
Fault Condition 1: If all the LEDs on the controller card are off, try the
following:
Press the eco-friendly button on the active master control card to
verify that the LEDs on the cards are on.
Check that the card is completely installed in the slot and that the
front plate is flush with the front of the chassis.
Fault Condition 2: If the controller card has a state of Up-Up-Degraded
when you perform the SHOW CARD command in "Entering the
Management Software Commands" on page 213, you might not of
removed the battery insulator when you installed the card. (Refer to Figure
71 on page 130.) To confirm this, enter the SHOW CARD with the slot
number of the controller card to display additional information: For
example, to display information about the controller card in slot 4, you
enter:
show card 4
The card still has the battery insulator if the Card Fault section of the
window includes an "RTC Battery" fault. To resolve the problem, remove
