Step 1 Connect your management computer using Ethernet to Management 1/1.
Step 2 (Optional) Connect your management computer to the console port. The Firepower 2100 ships with a DB-9 to RJ-45
serial cable, so you will need a third-party serial-to-USB cable to make the connection. Be sure to install any necessary
USB serial drivers for your operating system.
Step 3 Connect the outside network to the Ethernet 1/1 port (labeled WAN). For Smart Software Licensing, the ASA needs
internet access so that it can access the License Authority.
Step 4 Connect the inside network to Ethernet 1/2.
Step 5 Connect other data interfaces as needed using SFP/SFP+ transceivers. Install SFP/SFP+/ transceivers in the Ethernet
network interfaces in the 4 fixed ports or in the network module (Firepower 2130/2140 only) taking care not to touch
the contacts in the rear.
Do not force an SFP transceiver into a socket. This can jam the transceiver and can cause permanent damage
to the transceiver, the chassis, or both.
