Before you install the Cisco ASA 5505 Adaptive Security Appliance, please read the Regulatory Compliance and Safety Information

for the Cisco ASA 5500 Series Adaptive Security Appliance document on Cisco.com or in the product CD that ships with the chassis.

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 adaptive security

appliance.

Step 3 Connect the AC power connector of the power cable to an electrical outlet. (The adaptive security appliance does not have a

power switch. Completing this step powers on the device.)

Step 4 Check the Power LED on the front of the adaptive security appliance; if it is solid green, the device is powered on.

Step 5 If you connected a PC to the adaptive security appliance to run ASDM, restart the PC. (The PC obtains a dynamic IP address

from the adaptive security appliance and must be restarted.)

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 Cisco ASA 5500 Series Hardware Installation Guide on the product CD or

Cisco.com.

5. Launching ASDM (Adaptive Security Device Manager)

Step 1 On the PC connected to the adaptive security appliance, launch a web browser. (Verify that Java and JavaScript are enabled in

your web browser. See "Requirements for Running ASDM" for information.)

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 Click Yes in each dialog box to accept the certificates. 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 in ASDM."

2. Installing the Chassis

The adaptive security appliance ships with a default configuration that includes two preconfigured networks (the Inside network and

the Outside network) and an Inside interface configured with dynamic addressing. Clients on the Inside network obtain a dynamic IP

address from the adaptive security appliance so that they can communicate with each other as well as with devices on the Internet.

Step 1 Connect one end of a yellow straight-through Ethernet cable to port 0 on the adaptive security appliance. (By default, switch

port 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 straight-through Ethernet cables to ports 1 through 7.

Note Connect a PC to the adaptive security appliance so that you can run Adaptive Security Device Manager (ASDM). See "4.

Initial Configuration Considerations."

Step 3 Connect PoE devices (such as Cisco IP Phones or network cameras) with straight-through Ethernet cables to switch ports 6 or

7 (the only ports providing power to PoE devices).

Web Server

If you connect a server (such as a web server) to the adaptive security appliance, you can use ASDM to make services on that server

accessible by internal and external users. See "7. (Optional) Making Internal Services Accessible from the Internet."

4. Initial Configuration Considerations

The adaptive security appliance ships with a default configuration that, in most cases, is sufficient for your basic deployment. You

configure the adaptive security appliance by using Adaptive Security Device Manager (ASDM). ASDM is a graphical interface that allows

you to manage the adaptive security appliance 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 adaptive security appliance through ASDM and the CLI

• When using the adaptive security appliance as a VPN endpoint (using the SSL VPN features):

The hostname, domain name, and DNS server names

–

Setting a static Outside interface IP address

–

Creating an identity certificate

–

Configuring 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 in ASDM."

Requirements for Running ASDM

The PC connected to the adaptive security appliance must meet the following requirements to run ASDM.

Operating System and Version

Microsoft Windows Vista

Microsoft Windows XP

Microsoft Windows 2003 Server (English or Japanese)

Microsoft Windows 2000 (Service Pack 4 or higher)

Apple Macintosh

OS X

Red Hat Linux Desktop

Red Hat Enterprise Linux WS version 4 running

GNOME or KDE

1. Obtain Sun Java from

java.sun.com

2. With Apple Macintosh, only 32-bit Java SE will be supported. Currently, this also excludes Java 6. The 32-bit Java can run on a 64-bit Mac OS.

6. Running the Startup Wizard in ASDM

Run the Startup Wizard to modify the default configuration so that you can customize the security policy to suit your deployment.

What you set:

• Hostname

• Domain name

• Administrative

passwords

• IP address of

Outside interface

• Interfaces, such as

DMZ interfaces

• Address translation rules

• Dynamic IP address

settings for Inside interface

To run the Startup Wizard:

Step 1 In the main ASDM window, choose Wizards > Startup Wizard.

Step 2 Follow the instructions in the Startup Wizard to configure your adaptive security appliance.

If you get an error when launching the wizard requesting a DES license or a 3DES-AES license or you want to review your license

information, choose Configuration > Device Management > Licensing.

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 in the window.)

After running the Startup Wizard, you can run other wizards to configure remote access with the adaptive security appliance. See "8.

(Optional) Running the IPsec VPN Wizard in ASDM" and "9. (Optional) Running the SSL VPN Wizard in ASDM."
