How to install Cisco Firepower 1140 Network Security/Firewall Appliance

• Unpack the appliance, verify the kit contents, and ensure you have the necessary mounting hardware, power cables, and network cables required for your rack and site.
• Mount the 1140 in a standard 19-inch rack (or place on a suitable secure surface) and connect the power supply. If your deployment requires redundancy, configure the second power path and verify both units power on correctly.
• Connect the management plane: attach the management interface to your trusted network or management VLAN. Ensure there is access from your security operations center or IT team for initial setup.
• Power on the device and access the initial setup flow via the local console or the default management IP as directed by the user guide. Use the onboarding wizard or the Firepower Device Manager (FDM) to begin configuration.
• Configure the operating environment: set an initial admin account, configure network interfaces, and assign IP addresses, gateway, and DNS as required for your environment. Establish the management network separation to protect control traffic.
• Register the device with Cisco Secure Firewall Management Center (or enable local management via FDM), apply the appropriate license, and ensure the 1140 can pull the latest security signatures and updates.
• Define security policies: create access control policies, enable threat defense features (IPS/IDS), SSL inspection policies, URL filtering, and application controls tailored to your users and devices.
• Install and verify updates: run software and signature updates to ensure the appliance has the latest protections against known and emerging threats.
• Test baseline connectivity and security posture: verify legitimate traffic passes as expected, while malicious or policy-violating traffic is blocked or redirected for inspection. Validate VPNs (IPsec or SSL VPN if required) and high-availability failover if configured.
• Document the deployment: record the configuration, policy decisions, licensing, and contact points for ongoing management and incident response.

Frequently asked questions

• Q: What is the Cisco Firepower 1140 used for?

  A: The Cisco Firepower 1140 is a threat-focused Next-Generation Firewall appliance designed to protect networks by integrating firewalling, intrusion prevention, malware protection, URL filtering, and application control.
