The Brocade FCX 624-E, FCX 624-I, FCX 648-E, and FCX 648-I devices include a slot on the front
panel for a four-port 1 Gbps SFP module, or a four-port 10 Gbps SFP+ module. The 1 Gbps SFP
module operates at 1 Gbps full duplex, and the 10 Gbps SFP+ module operates at 10 Gbps full duplex.
FCX-I and FCX-E devices can be used in a homogeneous stack by installing the optional 4-port 10
Gbps SFP+ module, and connecting devices using standard duplex LC cables. These devices cannot
be combined in a stack with non-FCX devices. For detailed information about how to configure FCX
devices in a homogeneous stack, see the FastIron Ethernet Switch Stacking Configuration Guide .
