Firepower 7000 and 8000 Series Installation Guide
Chapter 4 Installing a Firepower Managed Device
Using Devices in a Stacked Configuration
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.

Using Devices in a Stacked Configuration
You can increase the amount of traffic inspected on network segments by combining the resources of
identically configured devices in a stacked configuration. One device is designated as the primary device
and is connected to the network segments. All other devices are designated secondary devices, and are
used to provide additional resources to the primary device. A Firepower Management Center creates,
edits, and manages the stacked configuration.
The primary device contains sensing interfaces and one set of stacking interfaces for each secondary
device connected to it. You connect the sensing interfaces on the primary device to the network segments
you want to monitor in the same way as a non-stacked device. You connect the stacking interfaces on the
primary device to the stacking interfaces on the secondary devices using the stacking cables. Each
secondary device is connected directly to the primary device using the stacking interfaces. If a secondary
device contains sensing interfaces, they are not used.
You can stack devices in the following configurations:
