3. Powering on and Verifying Interface Connectivity
Step 1 Connect the power supply adaptor to the power cable.
Step 2 Connect the rectangular connector of the power supply adaptor to the power connector on the rear panel of the ASA.
Step 3 Connect the AC power connector of the power cable to an electrical outlet. (The ASA does not have a power switch. Completing
this step powers on the device.)
Step 4 Check the Power LED on the front of the ASA; if it is solid green, the device is powered on.
Step 5 Check your management PC to make sure it received an IP address on the 192.168.1.0/24 network using DHCP.
Step 6 Check the LINK/ACT indicators to verify interface connectivity.
Interface Connectivity
Each Ethernet interface has an LED to indicate a physical link is established. When the LED is solid green, a link is established. When
the LED is flashing green, there is network activity.

If a LINK/ACT LED is not lit, the link could be down due to a duplex mismatch. If auto-negotiation is disabled, verify you are using
a straight-through Ethernet cable.
For a description of all chassis components, see the hardware installation guide on Cisco.com.
5. Launching ASDM
See the ASDM release notes on Cisco.com for the requirements to run ASDM.
Step 1 On the PC connected to the ASA, launch a web browser.
Step 2 In the Address field, enter the following URL:
https://192.168.1.1/admin
The Cisco ASDM web page appears.
Step 3 Click Run Startup Wizard.
Step 4 Accept any certificates according to the dialog boxes that appear. The Cisco ASDM-IDM Launcher appears.
Step 5 Leave the username and password fields empty and click OK.
The main ASDM window appears and the Startup Wizard opens. See "6. Running the Startup Wizard."

2. Installing the Chassis
The ASA ships with a default configuration that includes two preconfigured networks (the Inside network and the Outside network)
and an Inside interface configured for a DHCP server. Clients on the Inside network obtain a dynamic IP address from the ASA so that
they can communicate with each other as well as with devices on the Internet.
Step 1 Connect one end of a yellow Ethernet cable to Ethernet 0 on the ASA. (By default, Ethernet 0 is the Outside interface.) Connect
the other end to a cable/DSL/ISDN modem (the Outside network).
Step 2 Connect your devices (such as PCs, printers, and servers) with Ethernet cables to Ethernet 1 through 7.
Note Connect a PC to the ASA so that you can run the Adaptive Security Device Manager (ASDM). See "4. Initial
Configuration Considerations."
Step 3 Connect Power over Ethernet (PoE) devices (such as Cisco IP Phones or network cameras) with Ethernet cables to switch ports
6 or 7 (the only ports providing power to PoE devices).

If you connect a server (such as a web server) to the ASA, you can use ASDM to make services on that server accessible by internal and
external users. See "7. (Optional) Allowing Access to Public Servers Behind the ASA."
4. Initial Configuration Considerations
The ASA ships with a default configuration that, in most cases, is sufficient for your basic deployment. You configure the ASA by using
ASDM. ASDM is a graphical interface that allows you to manage the ASA from any location by using a web browser.
However, changing certain settings is recommended or required. For example, you should change the following settings from their
defaults:
• The privileged mode (enable) password that is required to administer the ASA through ASDM and the CLI
• When using the ASA as a VPN endpoint (using the SSL VPN features):
The hostname, domain name, and DNS server names
–
Outside interface IP address to a static address
–
Identity certificate
–
WINS names when access to Windows file shares is required
–
Use the Start up Wizard in ASDM to make these changes. See "6. Running the Startup Wizard."
6. Running the Startup Wizard
Run the Startup Wizard to modify the default configuration so that you can customize the security policy to suit your deployment.
Using the startup wizard, you can set the following:
• Hostname
• Static routes
• Domain name
• DHCP server
• Administrative passwords
• Network address translation rules
• Interfaces
• and more...
• IP addresses
Step 1 If the wizard is not already running, in the main ASDM window, choose Wizards > Startup Wizard.
Step 2 Follow the instructions in the Startup Wizard to configure your ASA.
Step 3 While running the wizard, you can accept the default settings or change them as required. (For information about any wizard
field, click Help.)
