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.
