Overview of Fabric Module Support
This switch supports the following fabric modules:
• Fabric 2 (N77-C7706-FAB-2)
• Fabric 3 (N77-C7706-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.
To specify a different maximum number of fabric modules for your system, use the hardware fabrics max
number command. To verify the status of the installed fabric modules, use the
show module xbar
command.
To verify the amount of reserved power, use the
show environment power
command.
Before you begin
• Make sure that the fabric modules that you are using are installed in slots 1 through
x
where
x
is the new
maximum number of fabric modules.
