Chapter 4 Installing a Firepower Managed Device
Using Devices in a Stacked Configuration
•
up to four Firepower 8250s
•
a Firepower 8260 (a 10G-capable primary device and a secondary device)
•
a Firepower 8270 (a 40G-capable primary device and two secondary devices)
•
a Firepower 8290 (a 40G-capable primary device and three secondary devices)
•
up to four Firepower or AMP 8350s
•
a Firepower or AMP 8360 (a 40G-capable primary device and a secondary device)
•
a Firepower or AMP 8370 (a 40G-capable primary device and two secondary devices)
•
a Firepower or AMP 8390 (a 40G-capable primary device and three secondary devices)
For the Firepower 8260 and 8270 devices and Firepower or AMP 8360 and 8370 devices, you can stack
additional devices for a total of four devices in the stack.
One device is designated as the primary device and is displayed on the Firepower Management Center’s
web interface with the primary role. All other devices in the stacked configuration are secondary and
displayed in the web interface with the secondary role. You use the combined resources as a single entity
except when viewing information from the stacked devices.
Connect the primary device to the network segments you want to analyze in the same way that you would
connect a single Firepower 8140, Firepower 8250, and Firepower or AMP 8350. Connect the secondary
devices to the primary device as indicated in the stack cabling diagram.
Caution
You
must
have management interfaces configured and working for all device stack members. Register all
devices as single devices, stack them, and never remove or disable the management interfaces for stacked
secondary devices. This allows each stack member to report health and exchange configuration
information.
After the devices are physically connected to the network segments and to each other, use a Firepower
Management Center to establish and manage the stack.
The following sections provide more information on how to connect and manage stacked devices:

Connecting the Firepower 8140
You can connect two Firepower 8140s in a stacked configuration. You must use one 8000 Series stacking
cable to create the physical connection between the primary device and the secondary device. For more
information on using the stacking cable, see
Using the 8000 Series Stacking Cable, page 4-18
.
Install the devices in your rack so you can easily connect the cable between the stacking modules. You
can install the secondary device above or below the primary device.
Connect the primary device to the network segments you want to analyze in the same way that you would
connect a single Firepower 8140. Connect the secondary device directly to the primary device.
The following graphic shows a primary device with a secondary device installed below the primary
device.
