Firepower 7000 and 8000 Series Installation Guide
Chapter 4 Installing a Firepower Managed Device
Using Devices in a Stacked Configuration
To connect a Firepower 8140 secondary device:
Step 1
Use an 8000 Series stacking cable to connect the left stacking interface on the primary device to the left
stacking interface on the secondary device, then use the Firepower Management Center that manages the
devices to establish the stacked device relationship in the system. Note that the right stacking interface
is not connected. See
Managing Stacked Devices, page 4-19
.
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.
Connecting the Firepower 82xx Family and Firepower and AMP 83xx Family
You can connect any of the following configurations:
•
up to four 8250s
•
up to four Firepower 8350s or four AMP8350s
•
a Firepower 8260 (a 10G-capable primary device and a secondary device)
•
a Firepower or AMP 8360 (a 40G-capable primary device and a secondary device)
•
a Firepower 8270 (a 40G-capable primary device and two secondary devices)
•
a Firepower or AMP 8370 (a 40G-capable primary device and two secondary devices)
•
a Firepower 8290 (a 40G-capable primary device and three secondary devices)
•
a Firepower or AMP 8390 (a 40G-capable primary device and three secondary devices)
You can stack additional devices for a total of four devices in the stack for the following configurations:
•
Firepower 8260 and 8270
•
Firepower or AMP 8360
•
Firepower or AMP 8370
You must use two 8000 Series stacking cables for each secondary device you want to connect to the
primary device. For more information on using the stacking cable, see
Using the 8000 Series Stacking
Install the devices in your rack so you can easily connect the cables between the stacking modules. You
can install the secondary devices 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 8250 or 8350 (Firepower or AMP). Connect each secondary device directly
to the primary device as required for the number of secondary devices in the configuration.
