Firepower 8000 Series Hardware Installation Guide
Chapter 3 Installing a Firepower 8000 Series Device
Using Devices in a Stacked Configuration
To connect a 8250 or a 8350 secondary device:
Step 1
Use an 8000 Series stacking cable to connect the left interface on the stacking module on the primary
device to the left interface on the stacking module on the secondary device.
Step 2
Use a second 8000 Series stacking cable to connect the right interface on the stacking module on the
primary device to the right interface on the stacking module on the secondary device.
Step 3
Repeat steps 1 and 2 for each secondary device you want to connect.
Step 4
Use the Firepower Management Center that manages the devices to establish the stacked device
relationship and manage their joint resources. See
Managing Stacked Devices, page 3-15
.
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.
Using the 8000 Series Stacking Cable
The 8000 Series stacking cable has identically-keyed ends, each with a latch to secure the cable in the
device and a latch release tab.
