Identifying the Sensing Interfaces
Tip
For best performance, use the interface sets consecutively. If you skip interfaces, you may experience
degraded performance.
Firepower 8000 Series Stacking Module
A stacking module combines the resources of two or more identically configured appliances. The
stacking module is optional on the following 8000 Series models:
•
Firepower 8140 and 8250
•
Firepower and AMP 8350
The stacking module is included in the following 8000 Series stacked configurations:
•
Firepower 8260, 8270, and 8290
•
Firepower and AMP 8360, 8370, and 8390
The stacking module allows you to combine the resources of two devices, using one as the primary
device and one as the secondary. Only the primary device has sensing interfaces. The following devices
can use the stacking module:
•
The Firepower 8140, 8250, and 8350 can be delivered with the stacking module.
•
The Firepower 8260 stacked configuration is delivered with one stacking module in the primary
device and one stacking module in the secondary device.
•
The Firepower and AMP 8360 stacked configurations are delivered with one stacking module in the
primary device and one stacking module in the secondary device.
•
The Firepower 8270 stacked configuration is delivered with two stacking modules in the primary
device and one stacking module in each of the two secondary devices.
•
The Firepower and AMP 8370 stacked configurations are delivered with two stacking modules in
the primary device and one stacking module in each of the two secondary devices.
•
The Firepower 8290 stacked configuration is delivered with three stacking modules in the primary
device, and one stacking module in each of the three secondary devices.
•
The Firepower and AMP 8390 stacked configurations are delivered with three stacking modules in
the primary device, and one stacking module in each of the three secondary devices.
