Overview of 40 Gbps breakout ports
A 40 Gbps breakout cable can be used on ICX 7750 standalone units to break out certain 40 Gbps
ports into four 10 Gbps sub-ports.
The 40 Gbps breakout cable is available for use on ICX 7750-48C, ICX 7750-48F, and ICX 7750-26Q
models.
NOTE
Any interface-level configuration must be removed from a 40 Gbps port before it can be broken out into
sub-ports. Refer to Configuring 40 Gbps breakout ports on page 378 for more information.
NOTE
Breakout can be configured only when the device is in store-and-forward mode. Breakout is not
supported in cut-through mode.
NOTE
Stacking cannot be enabled on ICX 7750 units that have breakout configuration on any 40 Gbps ports.
Ports available for breakout are shown for each model in the following table. Refer to the ICX 7750
Ethernet Switch Hardware Installation Guide for information on installing breakout cables.
