FCX IronStack configuration
Configuring FCX stacking ports
Brocade FCX-S and FCXS-F devices have two 10 Gbps ports on the front panel and two 16 Gbps
ports on the rear panel. All of these ports may be used as stacking ports, however the non-default
ports must be configured as stacking ports when setting up your FCX-S or FCXS-F IronStack.
FCX-I and FCX-E devices do not have 16 Gpbs ports on the rear panel. These devices may be used
in an IronStack by installing the 10 Gbps 4-port SFP+ module in the module slot on the front panel.
Once you have installed one of these modules, ports 1 and 2 act as the default stacking ports.
However, you can also use these ports to pass regular traffic, after disabling the stacking default.
Refer to “Changing default stacking port configurations” on page 261.
NOTE
If you are adding FCX-E or FCX-I devices to a stack containing FCX-S or FCXS-F devices, you must
reconfigure the stacking ports on the FCX-S or FCXS-F devices to be the 10 Gbps ports on the front
panel. You can then connect all of the devices in a stack using front panel ports.
Changing FCX-S and FCXS-F CX4 ports from 16 Gbps to 10 Gbps
You can configure the 16 Gbps CX4 ports to operate as 10 Gbps ports using the speed-duplex
command, as shown in the following example.
Syntax: speed-duplex [10-full | 10-half | 100-full | 100-half | 1000-full-master | 1000-full-slave
|10g-full | auto]
• 10-full - 10M, full duplex
• 10-half - 10M, half duplex
• 100-full - 100M, full duplex
• 100-half - 100M, half duplex
• 1000-full-master - 1G, full duplex, master
• 1000-full-slave - 1G, full duplex, slave
• 10g-full - 10G, full duplex
• auto - Autonegotiation
NOTE
Both ends of a link must be configured for 10 Gbps for the link to operate as 10 Gbps. If you want
the link to operate as a 16 Gbps link, both ends of the link must be configured for 16 Gbps.
