Figure 7. Ethernet Line and Controller Cards Slots
Slots 1 to 4 and 7 to 12 are for the Ethernet line cards. The cards may be
installed in any order or variety in the slots. The only exception is the AT-
SBx81XS16 Line Card, which is supported in slots 1 to 4, 7 and 8, but not
slots 9 to 12.
Slots 5 and 6 are for the AT-SBx81CFC960 Controller Fabric Card, of
which there must be at least one in the chassis. You may add a second
controller to add redundancy or to increase the available traffic bandwidth
of the chassis. The chassis has a backplane bandwidth of up to 40 Gbps
for each Ethernet line card slot with one controller card and up to 80 Gbps
for each slot with two cards.
