ICX 7750 Stack Configuration Overview

The following table provides an overview of ICX 7750 stacking capabilities.

ICX 7750 Stacking Capability

Stacking Capability ICX 7750 Additional Information
Topologies supported Ring and linear Refer to ICX 7750 stacking topologies.
Maximum stack size 12 Stacking only. Can serve as Control Bridge stack in 802.1br (Campus Fabric) configurations.
Maximum stacking distance 40 kilometers Refer to FastIron stacking distances and optics by device and Installing the ICX 7750 in a remote stack for more information.
ICX 7750 model combinations Allowed ICX 7750-48C, ICX 7750-48F, and ICX 7750-26Q models can be combined in the same stack.
Stacking ports

12 total ports available simultaneously:

Six 40-Gbps ports, Module 2: 1/2/1 to 1/2/6 (Front)

and

Six 40-Gbps ports, Module 3: 1/3/1 to 1/3/6 (Rear)

Refer to "Valid-stack-port sets" in this table for information on using Module 2 (right front) and Module 3 (rear) simultaneously for stacking.
Valid-stack-port sets

There are 6 valid-stack-port sets:

(x/2/1, x/2/4, 3)

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

(x/2/1, x/3/1, 6)

(x/2/5, x/2/6, 1)

(x/3/5, x/3/6, 1)

(x/2/5, x/3/5, 2)

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

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

Refer to ICX 7750 stacking topologies for port locations.

Reconfigurable ports Use the stack-port and stack-trunk commands to reconfigure ports.  
Trunks Up to two stack trunks
Note: To set up long-distance stacking trunks on 48-port units, refer to Installing the ICX 7750 in a remote stack.

Refer to "Valid-stack-port sets" in this table for common trunk configurations.

Linear-topology trunks The following maximum linear-topology trunks are supported:

1/2/1 to 1/2/6 and 1/3/1 to 1/3/6

or

1/2/5 to 1/2/6 and 1/3/5 to 1/3/6

Refer to Support for 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. No license required for Premium features. For more information on ICX 7750 license options, refer to the RUCKUS FastIron Software Licensing Guide.
Configuration options Manual and automatic, including stack interactive-setup and 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 applications. Refer to the RUCKUS FastIron Software Upgrade Guide for more information.
Stacking commands All stacking CLI is supported on ICX 7750 devices unless otherwise stated on the command reference page.
