Find Your Device's Serial Number
Connecting to the Firewall Using a Console Cable
You can connect a console cable from a device like a laptop to your Firepower firewall, open up a terminal
window, and enter a few commands to display the device's serial number.
Note
This procedure is for advanced users who are comfortable working with a command line interface and, possibly,
installing software drivers on their laptops. Here is the procedure to connect a computer to the Firepower
firewall using a console cable and to retrieve the device's serial number in a terminal window:
1. See
"Connect to the Console
console cable. Though the commands are explained in the Firepower 1010 Hardware Installation Guide,
they will be the same for the 1100 series devices and 2100 series devices.
There are two types of console ports for the 1010 and 1100 series devices. You could use either the
"USB-A to B" console cable that came with the firewall or a DB-9 to RJ-45 serial cable.
The Firepower 2100 ships with only a DB-9 to RJ-45 serial cable. When using this cable, 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.
2. Log in to the device as the admin user. If the device has not been configured, you will be asked to create
a new password for the admin.
