The components on the card are identified in Figure 22.
Figure 22. AT-SBx81CFC400 Controller Fabric Card
Where two controller cards are installed in the chassis, they provide an active/active architecture. The packet processors on both controller cards are fully utilized to double the available backplane bandwidth from 40 to 80 Gbps per Ethernet line card.
One of the controller cards becomes the active master. In normal operations, this is the controller card in slot 5. The active master manages the system and processes CPU bound network traffic. The standby master runs all network protocol modules and is kept in sync with the active master card, so as to be available in hot-standby for near instantaneous fail over, if required.
If the active master card is hot-swapped out, the standby master becomes the active master. It takes over all control functions almost instantaneously. Testing has shown no noticeable disruption to streaming video.
You can determine the state of the controller card by viewing the CFC LED on the card. The controller card is the active master when the LED is solid green and the standby master when the LED is solid amber.
SYS Status LEDs The SYS (System) Status LEDs on the controller fabric card display general status information about the controller card, power supplies, and fan module. The LEDs are defined in Table 10 on page 46.
