2. Installing the Chassis
Note Read the safety warnings in the Regulatory Compliance and Safety Information (RCSI), and follow proper safety procedures
when performing the steps in this guide. See
for links to the RCSI and other documents.
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.
1. Verifying the Package Contents
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
Step 3 Connect Power over Ethernet (PoE) devices (such as Cisco IP Phones or network cameras) with Ethernet cables to switch ports

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."
3. Powering on and Verifying Interface Connectivity
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
Step 1 Connect the power supply adaptor to the power cable.
ASDM. ASDM is a graphical interface that allows you to manage the ASA from any location by using a web browser.
Step 2 Connect the rectangular connector of the power supply adaptor to the power connector on the rear panel of the ASA.
However, changing certain settings is recommended or required. For example, you should change the following settings from their
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.)
• The privileged mode (enable) password that is required to administer the ASA through ASDM and the CLI
Step 4 Check the Power LED on the front of the ASA; if it is solid green, the device is powered on.
• When using the ASA as a VPN endpoint (using the SSL VPN features):
Step 5 Check your management PC to make sure it received an IP address on the 192.168.1.0/24 network using DHCP.
The hostname, domain name, and DNS server names
Step 6 Check the LINK/ACT indicators to verify interface connectivity.
Outside interface IP address to a static address
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."
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.

Adaptive Security Appliance
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
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.
See the ASDM release notes on Cisco.com for the requirements to run ASDM.
Using the startup wizard, you can set the following:
Step 1 On the PC connected to the ASA, launch a web browser.
• Static routes
Step 2 In the Address field, enter the following URL:
• Domain name
• DHCP server
• Administrative passwords
• Network address translation rules
The Cisco ASDM web page appears.
• and more...
• IP addresses
Step 3 Click Run Startup Wizard.
Step 1 If the wizard is not already running, in the main ASDM window, choose Wizards > Startup Wizard.
Step 4 Accept any certificates according to the dialog boxes that appear. The Cisco ASDM-IDM Launcher appears.
Step 2 Follow the instructions in the Startup Wizard to configure your ASA.
Step 5 Leave the username and password fields empty and click OK.
Step 3 While running the wizard, you can accept the default settings or change them as required. (For information about any wizard
