Device Overview

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.

DIAG LED—(Orange) When lit, indicates the appliance is performing the 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.

Getting Started

Installation

Cisco SA 500 Series Security Appliances Administration Guide 13

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.

Getting Started

Installation

Cisco SA 500 Series Security Appliances Administration Guide 14

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.

Getting Started

Installation

Cisco SA 500 Series Security Appliances Administration Guide 15

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.

Getting Started

Installation

Cisco SA 500 Series Security Appliances Administration Guide 16

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 For 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.

NOTE For details about configuring the UC 500 and the security appliance to work

together, see the SA 500 Series Security Appliances Administration Guide

on Cisco.com. See the documentation links in the “Where to Go From

Here” section of this guide.

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

Getting Started with the Configuration Utility

Cisco SA 500 Series Security Appliances Administration Guide 18

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

NOTE The above 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 Ye s 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.
