Hot Swapping Switch Modules
The switch modules can be “hot swapped” (except for the Management
Module, it is not hot swappable), that is installed or replaced while the switch
is powered on (See Module Installation Notes on page 2-8). The procedures
differ slightly, though between adding new modules to an empty slot or
replacing modules with the same type, and exchanging the module with a
different type.
Adding or Replacing Modules
If a module has to be replaced with one of the same type, or you are expanding
the switch capability by adding a module in a slot where one was not previ-
ously installed (since the last switch reboot), the replaced or new module is
immediately operational; there is no interruption to the switch operation.
When you are replacing a module in a slot with another module of different
type, the new module does not immediately operate, since the switch contains
configuration (such as VLAN membership) involving ports of the older
module. Replacing the module does NOT automatically remove such config-
uration. To remove the older configuration, run the following command from
the command line interface:
no module X
where, X is the slot letter of the module to be replaced. After you run
command, the slot is restored to a state where no module was previously
installed. When you insert the new module, the module operates immediately.
