Stacking ports (rear panel)
The 100 GbE ports 1/3/1 and 1/3/2 are default stacking ports. Default stacking ports have the capability to accept special stacking
packets during a CLI-initiated command sequence of the Secure Setup utility.
The ports on the front-panel module (Module 2) cannot be used as stacking ports. The Module 2 ports operate in uplink mode when the
rear-panel Module 3 ports are operating in stacking mode. When the Module 3 ports operate in uplink mode, the Module 2 ports are
disabled.
Stacking configuration requirements
Before configuring the stack using the CLI, physically connect the devices using stacking cables. For information about configuring a
stack, refer to the
Ruckus FastIron Stacking Configuration Guide
.
Stacking cables
Use QSFP+/QSFP28 direct attached copper stacking cables or QSFP+/QSFP28 optics with fiber cables to connect the Ruckus
ICX 7650 devices in a stack. The copper cable lengths for 40 GbE ports are 0.5 meter, 1 meter, 3 meters, or 5 meters.
NOTE
Stacking cables are not included in the shipping carton and must be ordered separately.
Stack size
A traditional stack can contain a maximum of twelve Ruckus ICX 7650 devices. A stack cannot contain other device types.
Stacking topologies
Both linear and ring topologies are supported in a stack. In a linear stack topology, there is a connection between each switch that carries
two-way communications across the stack.
For example, in a four-unit stack using a linear topology, unit 1 connects to unit 2, unit 2 to unit 3, and unit 3 to unit 4.
