AT-SBx31CFC Central Fabric Controller Card
The AT-SBx31CFC Central Fabric Controller card has three primary 
functions:
Chassis Management 
 
The control card is used to monitor and 
configure the Ethernet line cards in the chassis. You may manage 
the chassis locally through the Console RS-232 port on the control 
card or remotely using Telnet, Secure Shell (SSH), and SNMP 
clients from workstations on your network.
Configuration Settings 
 The control card stores the configuration 
settings of the Ethernet line cards and downloads the settings to 
the cards when the chassis is powered on or new line cards are 
installed. The settings are stored in a database file in nonvolatile 
memory so that they are retained even when the chassis is reset or 
powered off.
Backplane Control 
 The control card manages the backplane of 
the chassis. The backplane is used by line cards to forward traffic 
to each other, which occurs when the ingress and egress ports of 
packets are located on different cards.
A single control card provides 200 Gbps of backplane bandwidth. 
You may install a second control card for a total of 400 Gbps of 
backplane bandwidth.
Here are the guidelines to the control card:
The chassis must have at least one control card. The line cards do 
not forward traffic without a control card in the chassis.
The chassis may have either one or two control cards.
Two control cards are recommended for redundancy and to 
increase the backplane bandwidth from 200 to 400 Gbps. 
The control cards must be installed in slots 4 and 5 in the chassis.
Here are other features of the AT-SBx31CFC Central Fabric Controller 
card:
LEDs for monitoring the status of the Ethernet line cards.
Power-saving eco-friendly button for turning the port and status 
LEDs on and off on the line cards and control cards.
Reset switch for resetting the chassis.
SD card slot for data storage and retrieval.
Console RS-232 for local management.
NET MGMT port and inband interface for remote Telnet, SSH, and 
SNMP management.
Hot swappable.
