If you are new
users of Cisco ASA 5500-X Series Next-Generation Firewalls, are you familiar
with the ASA 5500-X Series configuration?
There are different Cisco ASA CX models available in a wide range of sizes,
for small offices, branch locations, and Internet-edge deployments.
In this
article, we will share the simple start guide of Cisco ASA 5500-X Series, including the model ASA 5512-X, ASA 5515-X,
ASA 5525-X, ASA 5545-X, and ASA 5555-X.
First of all, let’s check the main package
contents of ASA 5512-X, ASA 5515-X, or ASA 5525-X, ASA 5545-X and ASA 5555-X.

additional or fewer items.
Power on the
ASA
The power turns on automatically when you plug in the power cable;
do not press the power button on the front panel. (For older models, the power does not turn
on automatically; check the hardware installation guide for more information).
3. Check the Status LED on the front of
the ASA; after it is solid green, the system has passed power-on diagnostics.
Modify the
Initial Configuration for the Software Module (Optional)
The ASA ships with a default configuration that enables Adaptive
Security Device Manager (ASDM) connectivity to the Management 0/0 interface.
When you use a software module such as the ASA FirePOWER module, we recommend
that you do not use the default configuration, which can
preclude the module from reaching the Internet for updates. This section
describes how to apply a new configuration so the module can access the
Internet. This configuration also enables a basic usable configuration for an inside
and outside network.
The following figure shows the suggested network deployment for the
ASA 5500-X with a software module:
Note: If you have an inside router instead of a
switch, you can skip this section and instead configure the ASA to route between
management and an inside network. In this case, configure the ASA and the
module Management 0/0 IP addresses to be on the same network. Be sure to
configure appropriate routes on the ASA and on the module so the management
network can reach the inside network, and vice versa.
This procedure lets you connect to the ASA console port and paste in
a new configuration that configures the following behavior:
- inside --> outside traffic flow
- outside IP address from DHCP
- DHCP for clients on inside
- Management 0/0 interface is Up, but otherwise unconfigured. The software module can then use this interface to access the ASA inside network and use the inside interface as the gateway to the Internet.
- ASDM access on the inside interface
To achieve the above configuration, perform the
following steps.
1. Connect
your computer to the ASA console port with the supplied console cable. You
might need to use a third party serial-to-USB cable to make the connection.
10. Cable the inside GigabitEthernet 0/1
interface, Management 0/0 interface, and your computer to a Layer 2 Ethernet
switch.
12. For software module configuration,
see the ASA
FirePOWER quick start guide, ASA
CX quick start guide, or IPS
quick start guide. Use the following network settings for the module:
4. Launch
ASDM
Using ASDM, you can use wizards to configure basic and advanced
features. ASDM is a graphical user interface that allows you to manage the ASA
using a web browser. See the ASDM
release notes on Cisco.com for the requirements to run ASDM.
How to…
1. On the computer connected to the ASA, launch a web browser. If you
are using the default configuration and did not use 3. Modify the Initial
Configuration for the Software Module (Optional), you need to connect the
computer to the Management 0/0 interface.
2. In the Address field, enter the
following URL: https://192.168.1.1/admin. The Cisco ASDM web
page appears.
ASDM-IDM
Launcher appears.
