AT-SBx31CFC Controller Fabric Card
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 20 Gbps, which may result in slower network
operations.
If the chassis has one controller card, examine the M/S LED on the card.
The LED should be solid green. If the LED is flashing amber, the card is
initializing its management software. Wait one or two minutes for the card
to complete the process and check the LED again. If it has not changed to
solid green, the card cannot complete the initialization process. Try
moving the controller card to the other controller card slot, slot 4 or 5, to
see if it will work in the new slot. You might also try connecting a terminal
or PC with a terminal emulator program to the Console RS232 port to
watch for any error messages.
If the chassis has two controller cards, check the M/S LEDs on both cards.
The LEDs should be solid green on one card and solid or flashing amber
on the other card. If the LEDs are both flashing amber, they are initializing
their management software. Wait one or two minutes for the cards to
complete the process and check the LEDs again. If both LEDs are still
flashing amber, the cards cannot complete the initialization process. Try
replacing the cards.
The controller card has an onboard battery to maintain the date and time
when the chassis is powered off or reset. If you manually set the date and
time but the card loses the information after you power off or reset the unit,
you may have forgotten to remove the battery insulator when you installed
the card in the chassis. The insulator is shown in Figure 75 on page 120.
The only way to remedy the problem is to remove the controller card from
the chassis and remove the battery insulator. If the chassis has only one
controller card, removing the card causes the Ethernet line cards to stop
forwarding traffic.
