AT-SBx81CFC400 Controller Fabric Card
The AT-SBx81CFC400 Controller Fabric Card has three primary
functions:
 Chassis Management — You may use the controller card 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 controller card or remotely using Telnet, Secure Shell
(SSH), and SNMP clients from workstations on your network.
 AlliedWare Plus Operating System and Configuration Settings —
The controller card stores the AlliedWare Plus Operating System
and configuration settings for the Ethernet line cards in the chassis
and downloads the files 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 Controller — The controller card manages the
backplane of the chassis, which the line cards use to forward traffic
to each other.
A single controller card provides 40 Gbps of backplane bandwidth
per line card slot. You may install a second controller card for 80
Gbps of backplane bandwidth per line card slot.
Here are the guidelines to the controller card:
 The chassis must have at least one controller card. The line cards
do not forward traffic if the chassis does not have a controller card.
 The chassis may have either one or two controller cards.
 Two controller cards are recommended for redundancy and to
increase the backplane bandwidth from 40 to 80 Gbps per line
card slot.
 Controller cards must be installed in slots 5 and 6 in the chassis.
Here are other features of the AT-SBx81CFC400 Controller Fabric Card:
 LEDs for monitoring the status of the Ethernet line cards.
 Power-saving eco-friendly button for turning the port and status
LEDs on or off on the line cards and controller cards.
 Reset switch for resetting the chassis.
 USB port for data storage and retrieval.
 Console RS-232 for local management.
 NET MGMT port for remote Telnet, SSH, and SNMP management.
 Hot swappable.
