ICX 7750 stacking configuration notes

• If an ICX 7750 has a 40-Gbps port configured for breakout into sub-ports, any attempt to enable the unit for stacking will
fail. Remove the breakout configuration before enabling stacking on the unit. Refer to the Ruckus FastIron Management
Configuration Guide for more information on breakout cable configuration.
• When adding a new unit on a linear stack, make sure that the last unit of the existing stack has both stack-ports or stack-
trunks configured.
• Unused stacking ports can be used as data ports. For example, you can elect to use only one valid-stack-port as a
stacking port and use the other valid-stack-port as a data port. Furthermore, when an ICX 7750 stacking module is not
configured for stacking, its stacking ports can be used as data ports. For example, they can be tagged or untagged or
configured as breakout ports.
• To configure a stack trunk manually on a stack unit, use the stack-trunk command. However, in a live production
environment, use the multi-stack-trunk command as described in
environment on page 147.
• Only ports that are in sequential order can be configured as a stacking trunk.
• A valid-stack-port, either port 1/2/1 or 1/2/4 in module 2 or port 1/3/1 or 1/3/4 in module 3, is always the first sequential
port in a trunk.
