default gateway: 192.168.45.1
Using an Ethernet cable, connect the network interface on the local computer to the management interface on the
appliance. Note that the management interface is preconfigured with a default IPv4 address. However, you can
reconfigure the management interface with an IPv6 address as part of the setup process.
To install the appliance:
1. Mount the appliance in your rack using the mounting kit and its supplied instructions.
2. Connect to the appliance using either a keyboard and monitor or an Ethernet connection.
— If you are using a keyboard and monitor to set up the appliance, use an Ethernet cable now to connect the
management interface to a protected network segment.
— If you plan to perform the initial setup process by connecting a computer directly to the appliance's
physical management interface, you will connect the management interface to the protected network when
you finish setup.
3. Connect the sensing interfaces to the network segments you want to analyze using the appropriate cables for
your interfaces:
— Copper Sensing Interfaces: If your device includes copper sensing interfaces, make sure you use the
appropriate cables to connect them to your network; see Cabling Inline Deployments on Copper Interfaces
in the Firepower 8000 Series Hardware Installation Guide.
— Fiber Adapter Card: For devices with a fiber adapter card, connect the LC connectors on the optional
multimode fiber cable to two ports on the adapter card in any order. Connect the SC plug to the network
segment you want to analyze.
— Fiber Tap: If you are deploying the device with an optional fiber optic tap, connect the SC plug on the
optional multimode fiber cable to the "analyzer" port on the tap. Connect the tap to the network segment
you want to analyze.
— Copper Tap: If you are deploying the device with an optional copper tap, connect the A and B ports on the
left of the tap to the network segment you want to analyze. Connect the A and B ports on the right of the
tap (the "analyzer" ports) to two copper ports on the adapter card.
For more information about options for deploying the managed device, see Deploying Managed Devices in the
Firepower 8000 Series Hardware Installation Guide.
Note that if you are deploying a device with bypass interfaces, you are taking advantage of your device's ability
to maintain network connectivity even if the device fails. See Testing an Inline Bypass Interface Installation in
the Firepower 8000 Series Hardware Installation Guide for information on installation and latency testing.
4. Attach the power cord to the appliance and plug into a power source.
If your appliance has redundant power supplies, attach power cords to both power supplies and plug them
into separate power sources.
5. Turn on the appliance.
6. If you are using a direct Ethernet connection to set up the appliance, confirm that the link LED is on for both
the network interface on the local computer and the management interface on the appliance.
If the management interface and network interface LEDs are not lit, try using a crossover cable. For more
information, see Cabling Inline Deployments on Copper Interfaces in the Firepower 8000 Series Hardware
Installation Guide.
