Hardware Overview
A reboot is necessary when a hot-pluggable module is replaced with a module 
of different type. Specifically, changing from a 40G module to a 10G module 
or from a 10G module to a 40G module requires a reboot. Plug-in modules 
with any port configured as a stacking port are not hot-swappable. Remove 
the stack-port configuration from a slot before plugging in a module.
You must execute a no slot or clear config command prior to inserting the 
new module. Note that changing the role of a port from stacking to Ethernet 
or vice-versa also requires a switch reboot.
If a no slot command is not issued prior to inserting a module, a message 
such as the following will appear: 
Card Mismatch: Unit:1 Slot:1 Inserted-Card: Dell 2 
Port QSFP Expansion Card Config-Card: Dell 4 Port 
10GBase-T Expansion Card
