12
Power Up the Appliance
Power up the appliance by pressing the On/Off switch on the front panel of the
Cisco S190. You must wait 10 minutes for the system to initialize each time you
power up the system. After the machine powers up, a solid green light indicates
that the appliance is operational.
Note If turned on quickly after connecting power to the appliance, the
appliance powers up, the fans spin and the LEDs turn on. Within 30-60
seconds, the fans stop and all LEDs turn off. The appliance powers on
31 seconds later. This behavior is by design to allow the system
firmware and controller to synchronize.

Wait at least 10 minutes for the system to complete the power up
sequence and the LEDs to turn green. If you turn the power off before
the initialization is complete, the appliance will NOT reach an
operational state and must be returned to Cisco.

Log In to the Appliance
You can log in to the Cisco S190 appliance using one of two interfaces: the
web-based interface or the command-line interface.
Web-Based Interface
Step 1 For web browser access via the Ethernet port (see the “Connect to the
Appliance” section on page 11), go to the Cisco S190 appliance
management interface by entering the following URL in a web browser:
http://192.168.42.42:8080
Step 2 Enter the following login information:
• Username: admin
• Password: ironport
Note The hostname parameter is assigned during system setup. Before you
can connect to the management interface using a hostname
(http://hostname:8080), you must add the appliance hostname and IP
address to your DNS server database.
Step 3 Click Login.
Command-Line Interface
Step 1 Access the command-line interface locally or remotely:
• To access the CLI locally, set up a terminal to connect to the serial
port using 9600 bits, 8 bits, no parity, 1 stop bit (9600, 8, N, 1) and
flow control set to Hardware. To physically connect the terminal,
see the “Connect to the Appliance” section on page 11).
• To access the CLI remotely, initiate an SSH session to the IP address
192.168.42.42.
Step 2 Log in as admin with the password ironport.

14
Step 3 At the prompt, run the systemsetup command.
Run the System Setup Wizard
The System Setup Wizard starts automatically when you access the appliance via
the web-based interface and displays the end user license agreement (also known
as the EULA).
Step 1 Accept the end user license agreement.
Step 2 Enter information from the “Document Network Settings” section on
page 4.
If you need additional information about the settings, choose Help and
Support > Online Help.
Step 3 Review the configuration summary page.
Step 4 Click Install this Configuration.
Step 5 The appliance may not appear to have accepted your configuration or
be performing the installation. This is because you have changed the IP
address, but the installation is underway.
Step 6 If you temporarily changed the IP address of your computer as
described above, change the IP address settings back to the original
values.
Step 7 Ensure that your laptop and the appliance are connected to the
network.
Step 8 Log in to the appliance again, at the hostname or IP address that you
noted in the “Plan the Installation” section on page 6. Use the username
admin and the new password that you entered in the wizard.
The Cisco M390 Content Security Management Appliance uses a
self-signed certificate that may trigger a warning from your web
browser. You can simply accept the certificate and ignore this warning.
Step 9 Be sure to keep your new administrator password in a safe place.

15
Check for Available Upgrades
After logging in to the appliance, look at the top of the web browser window for
an upgrade notification (or for a notice in the command-line interface.) If an
upgrade is available, evaluate whether you should install it.
Details about each release are available in the release notes for that Async OS
version.
Configure Network Settings
Depending on your network configuration, your firewall may need to be
configured to allow access using the following ports. SMTP and DNS services
must have access to the Internet.
The web security appliance must be able to listen on the following ports:
• FTP: port 21, data port TCP 1024 and higher
• HTTP: port 80
• HTTPS: port 443
• Management access: ports 8443 (HTTPS) and 8080 (HTTP)
• SSH: port 22
The web security appliance must be able to make an outbound connection on
the following ports:
• DNS: port 53
• FTP: port 21, data port TCP 1024 and higher
• HTTP: port 80
• HTTPS: port 443
• LDAP: port 389 or 3268
• LDAP over SSL: port 636
• LDAP with SSL for global catalog queries: port 3269
• NTP: port 123
• SMTP: port 25
Note If you do not open port 80 and 443, you cannot download feature keys.

16
Configuration Summary
Item Description
Management You can manage the web security appliance
from the management port by entering
http://192.168.42.42:8080
or by using the IP address assigned to the
management interface after you have
completed the System Setup Wizard.
If you reset your configuration to factory
default settings (for example, by re-running
the System Setup Wizard), you can access
the management interface only from the
MGMT port (http://192.168.42.42:8080),
so ensure that you have a connection to the
MGMT port.
Also, verify that you open firewall ports 80
and 443 on your management interface.
Data After running the System Setup Wizard, at
least one port on the appliance is configured
to receive web traffic from the clients on the
network: M1 only; M1 and P1; 
M1, P1 and P2; P1 only; or P1 and P2.
Note If you configured the web proxy in
explicit forward mode, the
applications on the client machines
must be configured to explicitly
forward web traffic to the web
security appliance’s web proxy
using the IP address configured for
data, either M1 or P1.

17
Additional Configuration
Congratulations. Now that you have completed the installation and basic
configuration, you can start using your 
Cisco S190 Web Security Appliance. You may wish to consider taking some of
the following steps to get more out of the appliance:
User Policies
Use the web interface to create policies that define which users can access which
web resources as necessary.
• Identify Users—Choose Web Security Manager > Identification Profiles to
define groups of users that can access the Internet.
• Define Access Policies—Choose Web Security Manager > Access Policies to
control user access to the Internet by configuring which objects and
applications to allow or block, which URL categories to monitor or block,
and web reputation and anti-malware settings.
You can also define several other policy types to enforce your organization’s
acceptable use policies by controlling access to the Internet. For example, you
can define policies for decrypting HTTPS transactions and other polices that
control upload requests.
Traffic Monitor After running the System Setup Wizard, one
or both L4 traffic monitor ports (T1 only or
both T1 and T2) are configured to listen to
traffic on all TCP ports. The default setting
for the L4 traffic monitor is monitor only.
During or after setup, you can configure the
L4 traffic monitor to both monitor and
block suspicious traffic.
Computer
Address
Remember to change your computer IP
address back to the original settings that
you noted in the “Temporarily Change Your
IP Address for Remote Access” section on
page 9.
