ICX 7450 Stack Configuration Overview

The following table provides an overview of ICX 7450 stacking capabilities. From FastIron release 08.0.30, 4 X 10-Gbps stacking is available from module 2 as an option.

ICX 7450 Stacking Capability

Stacking Capability ICX 7450 Additional Information
Topologies supported Ring and linear Refer to ICX 7450 stacking topologies.
Maximum stack size 12 units Any combination of ICX 7450 devices may be stacked.
Maximum stacking distance 100 meters, 300 meters, or 10 kilometers, depending on optic Refer to FastIron stacking distances and optics by device for more information.
Stacking ports

Two 40-Gbps ports in rear

or

4 X 10-Gbps ports as an option on front

Note: 40-Gbps stacking and 4 X 10-Gbps stacking cannot be used simultaneously in the same stack.
Note: Changing stacking ports from Modules 3 and 4 to Module 2 ports requires write memory and reload.
Modules 3 and 4, one port each. Four 10-Gbps ports are available as an option when a 4X10GF module is installed in slot 2. Refer to ICX 7450 stacking topologies for module locations.
Valid-stack-port sets

Factory set (x/3/1, x/4/1, 1)

or (x/2/1, x/2/3, 2)

Note: The third number of a set is the maximum number of ports in a stacking trunk. One indicates stack-port only.

Refer to the definition of valid-stack-port set in Stacking terminology for more information.

Refer to ICX 7450 stacking topologies for port locations.

Reconfigurable ports Use the stack-port and stack-trunk commands to reconfigure ports.

Stacking ports can be reconfigured as data ports.

Refer to Configuring 10 Gbps stacking ports on the ICX 7450 for more information.

Stack trunks

Two trunks are possible:

1/2/1 to 1/2/2 and 1/2/3 to 1/2/4

Supported on 10-Gbps ports only when a 4X10GF module is present in slot 2. Refer to Creating stack trunks on the ICX 7450 for more information.
Linear-topology trunks The ICX 7450-24P is the only model that supports linear trunks:

stack-trunk 1/3/1 and 1/4/1

stack-trunk 1/2/1 to 1/2/4

Refer to Configuring Two-unit Stack Linear-topology Trunks for more information.

Hitless switchover and hitless failover Supported Refer to Hitless stacking.
License requirements No license required for stack-port configuration Premium feature requires trust-based license. Refer to the RUCKUS FastIron Software Licensing Guide for information.
Configuration options Manual and automatic, including stack interactive-setup and stack zero-touch provisioning Refer to Stack construction methods.
Access methods TFTP, SCP Software images, boot images, and signatures can be downloaded to a stack using TFTP and SCP. Refer to the RUCKUS FastIron Software Upgrade Guide for more information.
Stacking commands These commands are not available on ICX 7450 devices, except as noted:

multi-stack-port, except when a 4X10GF module is present in slot 2

multi-stack-trunk, except when a 4X10GF module is present in slot 2

stack-trunk, except when a 4X10GF module is present in slot 2
