AT-SBx31CFC Central Fabric Controller Card
The consequences of a control card failure depend on the number of
control cards in the chassis. If the chassis has one control card and it fails,
all network operations stop. The Ethernet line cards stop forwarding all
network traffic until the control card is replaced.
If the chassis has two control cards and one fails, the Ethernet line cards
continue to forward traffic, but the traffic bandwidth across the backplane
is reduced from 400 to 200 Gbps, which, depending on the number of
Ethernet line cards present and the amount of traffic traversing the
backplane, may result in slower network operations.
If the chassis has one control 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 control card to the other control 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 control 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 control card has an onboard battery which it uses 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
72 on page 116. The only way to remedy the problem is to remove the
control card from the chassis and remove the battery insulator. If the
chassis has only one control card, removing the card causes the Ethernet
line cards to stop forwarding traffic.
