
Regardless of how you are connected to the device, you can use the CLI to set it up; see Initial Setup Using
the CLI, page 15 .
If you are setting up a reimaged device and you kept your network settings as part of the restore process, you can
access the CLI via SSH or a Lights-Out Management (LOM) connection. You can also browse to the device’s web
interface from a computer on your management network.
Caution: The procedures in this guide explain how to set up an appliance without powering it down. However,
if you need to power down for any reason, use the procedure in the Device Management Basics chapter in
the
Firepower Management Center Configuration Guide , the
system shutdown
command from the CLI on a
Firepower device, or the
shutdown -h now
command from an appliance’s shell (sometimes called expert
mode).
Initial Setup Using the Web Interface
In most cases, complete the setup process by logging into the device’s web interface and specifying initial
configuration options on a setup page.
Procedure
1. Direct your browser to
https:// mgmt_ip /
, where
mgmt_ip
is the IP address of the device’s management
interface.
— For a device connected to a computer with an Ethernet cable, direct the browser on that computer to the
default management interface IPv4 address:
https://192.168.45.45/
.
— For a device where network settings are already configured, use a computer on your management network
to browse to the IP address of the device’s management interface.
2. Log in using
admin
as the username and
Admin123
as the password.
See the following sections for information on initial setup options:
— Change Password, page 13
— Network Settings, page 13
— Firepower Device LCD Panel Configuration, page 13
— Remote Management, page 13
— Time Settings, page 13
— Detection Mode, page 14
— Automatic Backups, page 15
— End User License Agreement, page 15
3. When you are finished, click Apply .
The device is configured according to your selections. You are logged into the web interface as the
admin
user,
which has the Administrator role.
4. Log out of the device.
The device is ready to be added to its Firepower Management Center.
Note: If you connected directly to the device using an Ethernet cable, disconnect the computer and connect
the device’s management interface to the management network. If you need to access the device’s web
interface at any time, direct a browser on a computer on the management network to the IP address or host
name that you configured during setup.
