configuration. In this case, you need to enter the purge module 3 running-config command to clear
the old configuration in Switch A before using the IP address.
Shut Down or Power Up an I/O Module
You can shutdown or power up an I/O module by using the poweroff module or no poweroff module
command to specify the module by its slot number in the chassis.
Step 1 Start the configuration mode by entering the configure terminal command.
Example:
switch# configure terminal
switch(config)#
Step 2 Shutdown the module by entering the [no] shutdown module slot_number command.
Example:
switch(config)# poweroff module 1
switch(config)#
Example:
switch(config)# no poweroff module 1
switch(config)#
Overview of Fabric Module Support
This switch supports the following fabric modules:
• Fabric 2 (N77-C7710-FAB-2)
• Fabric 3 (N77-C7710-FAB-3)
You can replace a Fabric 2 module with a Fabric 3 module during operations, but while there is a mix of fabric
module types, all of the fabric modules perform as Fabric 2 modules. If you reload a switch with Fabric 2 and
Fabric 3 modules installed, only the Fabric 3 modules will power up. To utilize the Fabric 3 module capabilities,
all of the installed fabric modules must be Fabric 3 modules.
Note
Change the Amount of Power Reserved for Fabric Modules
By default, each switch reserves enough power for the maximum quantity of fabric modules that can be
installed in its chassis. If you have installed fewer than the maximum number of fabric modules and need to
free up unused reserve power for I/O modules, you can power down the unused slots and specify a smaller
maximum number of modules.
