Brocade FCX Series Hardware Installation Guide - Manual (Page 46)

Modules that connect FCX E/I and FCX S/S-F devices in a stack TABLE 17
This FCX E/I module connects to These FCX S/S-F modules
4-port 10 Gbps SFP+ module
2-port 10 Gbps XFP module
NOTE
Trunking is not supported on the Brocade FCX Series.
Stacking configuration requirements
• Before configuring the stack using the CLI, physically connect the devices using stacking cables.
• To connect FCX S/S-F, and FCX E/I devices in a stack, you must reconfigure the default stacking
ports on the FCX S/S-F devices to be the ports on the two-port 10 Gbps XFP module on the front
panel using the default-port command.
• To use the ports in the 16/10 Gbps CX4 stacking module as data ports, you must reconfigure the
stacking ports using the longpreamble command.
• To change the default stacking ports on the 4-port 10 Gbps SFP+ module from ports 1 and 2 to
ports 3 and 4, you must reconfigure the default ports using the default-port command.
For information about configuring a stack, see the FastIron Ethernet Switch Stacking Configuration
Guide.
Stacking cables
To connect Brocade FCX Series devices in a stack, you need to use specific cables.
Cables used to connect Brocade FCX Series devices TABLE 18
To connect this FCX device To this FCX device Use this cable type
FCX S/S-F FCX S/S-F CX4 stacking cable
FCX E/I FCX E/I LC-LC MM fiber cables
FCX S/S-F FCX E/I LC-LC MM fiber cables
Stack size
A traditional stack can contain a combined maximum of eight FCX S, FCX S-F, FCS-E, and FCX-I
devices.
Stacking topologies
Both linear and ring topologies are supported. In a linear stack topology there is a connection between
each switch that carries two-way communications across the stack. This connection can use one port
or two ports per trunk.
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.
