Before you begin to use the security appliance, become familiar with the LEDs on
the front panel and the ports on the rear panel. Refer to the following illustrations
and descriptions.
Front Panel
•RESET Button—To reboot the security appliance, push and release the
Reset button. To restore the factory default settings, press and hold the
Reset button for 5 seconds.

power-on diagnostics. When off, indicates the appliance has booted
properly.
•POWER LED—(Green) When lit, indicates the appliance is powered on.
•DMZ LED—(Green) When lit, indicates the Optional port is configured as a
Demilitarized Zone or Demarcation Zone, which allows public services such
as web servers, without exposing your LAN.
•SPEED LED—(Green or Orange) Indicates the traffic rate for the associated
port. Off = 10 Mbps, Green = 100 Mbps, Orange = 1000 Mbps.

•LINK/ACT LED—(Green) When lit, indicates that a connection is being
made through the port. When flashing, the port is active.
•WLAN LED—(Green) When lit, indicates that wireless is enabled
(SA 520W).
Rear Panel
•POWER Switch—Turns the security appliance on or off.
•POWER Connector—Connects the security appliance to power using the
supplied power cable.
•LAN Ports—Connect computers and other network appliances to the
security appliance. The SA 520 and SA 520W have 4 LAN ports. The SA
540 has 8.
•OPTIONAL Port—Can be configured to operate as a WAN, LAN, or DMZ
port. A DMZ (Demilitarized Zone or Demarcation Zone) can be configured to
allow public access to services such as web servers without exposing your
LAN.
•WAN Port—Connects the security appliance to DSL, a cable modem, or
another WAN connectivity device.
•USB Port—Connects the security appliance to a USB device. You can use a
USB device to store configuration files for backup and restore operations.
NOTE The back panel of the SA 520W includes three threaded connectors for the
antennas.

Installation
This section guides you through the installation of your security appliance. Refer to
the following topics:
•Installation Options, page 13
•Hardware Installation, page 16
Installation Options
You can place your security appliance on a desktop, mount it on a wall, or mount it
in a rack.
Placement Tips
•Ambient Temperature—To prevent the security appliance from
overheating, do not operate it in an area that exceeds an ambient
temperature of 104°F (40°C).
•Air Flow—Be sure that there is adequate air flow around the device.
•Mechanical Loading—Be sure that the security appliance is level and
stable to avoid any hazardous conditions.
To place the security appliance on a desktop, install the four rubber feet (included)
on the bottom of the security appliance. Place the device on a flat surface.

Wall Mounting
STEP 1 Insert two 17 mm screws, with anchors, into the wall 15 cm apart (about 5.9
inches). Leave 3-4 mm (about 1/8 inch) of the head exposed.

STEP 2 Position the unit so that the wall-mount slots are over the two screws. Slide the unit
down until the screws fit snugly into the wall-mount slots.
Rack Mounting
You can mount the security appliance in any standard size, 19-inch (about 48 cm)
wide rack. Each security appliance requires 1 rack unit (RU) of space, which is 1.75
inches (44.45 mm) high.
!
CAUTION Do not overload the power outlet or circuit when installing multiple devices in a
rack.

STEP 1 Remove the four screws from each side of the security appliance.
STEP 2 Place one of the supplied spacers on the side of the security appliance so that the
four holes align to the screw holes. Place a rack mount bracket next to the spacer
and reinstall the screws.
NOTE If the screws are not long enough to reattach the bracket with the spacer, attach the
bracket directly to the case without the spacer.
STEP 3 Install the security appliance into a standard rack as shown.
Hardware Installation
Follow these steps to connect the equipment:
STEP 1 Connect the security appliance to power.
STEP 2 If you are installing the SA 520W, screw each antenna onto a threaded connector
on the back panel. Orient each antenna to point upward.
STEP 3 For DSL, a cable modem, or other WAN connectivity devices, connect an Ethernet
network cable from the device to the WAN port on the back panel. Cisco strongly
recommends using Cat5E or better cable.
STEP 4 For network devices, connect an Ethernet network cable from the network device
to one of the dedicated LAN ports on the back panel.

STEP 5 If you are using a UC 500, connect an Ethernet network cable from the WAN port of
the UC 500 to an available LAN port of the security appliance.
STEP 6 Power on the security appliance.
STEP 7 Power on the connected devices. Each LED lights to show an active connection.
A sample configuration is illustrated below.
Congratulations! The installation of the security appliance is complete.
Getting Started with the Configuration Utility
The Configuration Utility web page is a web based device manager that is used to
provision the SA 500 Series Security Appliances. To use this utility, you must be
able to connect to the SA 500 Series Security Appliances from your
administration PC or laptop. You can access the router by using any web browser
(such as Microsoft Internet Explorer or Mozilla Firefox).
Connecting to the Configuration Utility
STEP 1 Connect your computer to an available LAN port on the back panel of the security
appliance.

STEP 2 Start a web browser, and enter the following address: 192.168.75.1
This address is the factory default LAN address of the security appliance. If you
change this setting in the LAN configuration, you will need to enter the new IP
address to connect to the Configuration Utility.
STEP 3 When the Security Alert appears, accept or install the certificate:
•Internet Explorer: Click Yes to proceed, or click View Certificate for details.
On the Certificate page, click Install the Certificate. Follow the instructions
in the Wizard to complete the installation.
•Firefox: Click the link to add an exception. Click the Add Exception button.
Click Get Certificate, and then click Confirm Security Exception.
•Safari: Click Continue to proceed, or click Show Certificate. On the
Certificate page, click Install the Certificate. Follow the instructions in the
Wizard to complete the installation.
