100-Gbps or 40-Gbps cable can be used on
and ICX 7850 standalone
units to break out certain 40-Gbps ports into four 10-Gbps subports and 100-Gbps
ports into
four 25-Gbps subports respectively.
The breakout ports can be broken out only when
stacking is not enabled, and any interface-level configuration must be removed
before it
can be broken out into subports.
Note: The ports listed in the tables ICX 7850 Ports Available for
Breakout and Ports Available for
Breakout can serve as a breakout ports if the stack enable command is not
configured on those ports. However, the stacking ports are always displayed in
three-tuple format (x/y/z) even when they have been configured as breakout ports.
For example, if port 1/2/1 is a breakout port, it appears in general configuration
or show command output as
1/2/1:1; however, any output that shows the port as a stack-port configuration
displays the port as 1/2/1.
Note: ICX 7850 devices do
not need to be in store-and-forward mode for breakout ports to be functional.
Ports available for breakout are shown for each
supported model in the following table. Refer to the RUCKUS ICX 7850 Switch
Hardware Installation Guide and RUCKUS ICX 7550 Switch
Hardware Installation Guide for information on installing breakout cables.
Note: On the , breakout is
supported only on module 2 stacking and uplink ports.

You can configure breakout ports at the
global configuration mode. After successful configuration and activation of breakout,
the
sub-ports are available for configuration. By default, all main 40 Gbps ports are
configured
to come up in 40 Gbps mode.
