Built-in SFP+ and Stacking Note
AX743 and rear module bays are preferred for ber stacking - rear bays are
pre-con gured for automatic Stacking mode. Just interconnect switches using
rear module bays for zero-touch local and/or distant stacking.
Starting with v8.0.3 software release, the two built-in SFP+ ports on the front
may also be used for stacking, although they are pre-con gured for regular
Ethernet mode. Con guration can be changed to enable front Stacking mode.

Local Stack Topology
When the switches are deployed in the same rack, one AX742
kit per switch is required for dual-ring topology, providing higher
resiliency and intelligent load balancing.
Each ring speed is 12 Gbps half duplex (24 Gbps full duplex).
Dual ring overall speed is 24 Gbps half duplex (48 Gbps full
duplex).
Distant Stack Topology
When the switches are deployed in several locations, two AX743
SFP+ host modules are required per switch, with the SFP+ optics
(AXM761, AXM762 or AXM763) for this hardware dual-ring
topology, providing highest resiliency and intelligent load balancing.
Each ring speed is 10 Gbps half duplex (20 Gbps full duplex).
Dual ring overall speed is 20 Gbps half duplex (40 Gbps full duplex).
Local and distant stack can be combined for maximum exibility
(example: “SMB Network Deployments” application, Page 3).
