3Connect the Cables

Follow these steps to connect the cables:

Step 1 Place the chassis on a flat, stable surface. The chassis is not rack mountable.

Step 2 Connect Port 0, the outside Ethernet port, to the public network:

a. Use the yellow Ethernet cable (72-1482-01) to connect the device to a switch or hub.

b. Use the orange Ethernet cable (72-3515-01) to connect the device to a cable/DSL/ISDN

modem.

Step 3 Connect your PC or other network devices with an Ethernet cable (not provided) to one of

the four switched inside ports (numbered 1 through 4).

Note Make sure that one of the PCs has TCP/IP installed and is configured to obtain an IP

address automatically through DHCP. This allows the PC to communicate with the

PIX 501 and the Internet as well as run the PDM Startup Wizard.

4Power On the PIX 501

Follow these steps to power on the PIX Firewall:

Step 1 Connect the small, round connector of the power supply cable to the power connector on the

rear panel.

Step 2 Connect the AC power connector of the power supply input cable to an electrical outlet.

Note The PIX 501 does not have a power switch. Completing Step 2 powers on the device.

5Check the LEDs

The LINK/ACT LED indicators on the front panel of the PIX Firewall are normally solid green when

a link is established and flashing green when the ports are active. Each inside Ethernet interface

(1 through 4) has two LEDs to indicate the operating speed and that the physical link is established.

Note If all LEDs are operating as expected (see Table 1), this concludes the hardware installation. The

pages that follow include instructions on running PDM and additional optional procedures.

Table 1 PIX 501 LEDs

LED State Description

POWER Green The device is powered on.

Off The device is powered off.

LINK/ACT Flashing

green Network activity, such as Internet access, is present.

Green The correct cable is in use, and the connected equipment has power.

Off No link is established.

Tip If the LINK/ACT LED does not light up, you might be using the

wrong type of cable. Try replacing the yellow (straight-through)

Ethernet cable with the orange (crossover) Ethernet cable.

VPNTUNNEL Green One or more IKE/IPSec VPN tunnels are active.

Off No VPN tunnels are active. The default configuration does not include

VPN. Thus, the VPN tunnel LED will only be enabled if VPN is added to

your configuration and a VPN tunnel is then established. Also, the LED

does not light up when PPTP/L2TP tunnels are established.

100 MBPS Green The interface is autonegotiated at 100-Mbps half or full duplex.

Flashing

green The interface is functioning at 10-Mbps half or full duplex.

6(Optional) Install a Cable Lock

The PIX 501 includes a slot that accepts standard desktop cable locks to provide physical security for

small portable equipment, such as a laptop computer. The cable lock is not included.

Follow these steps to install a cable lock:

Step 1 Attach the cable lock (not included) to the lock slot on the back panel of the PIX 501.

Step 2 Follow the directions from the manufacturer for attaching the other end of the device for

securing the PIX Firewall.

7Configuring the PIX 501

The PIX 501 comes with a factory default configuration that meets the needs of most broadband

networking environments. The factory default configuration on the PIX 501 protects your inside

network from any unsolicited traffic. It is configured to use DHCP on the outside interface to acquire its

IP address. A default DHCP server address pool is included for hosts on the inside interface.

PDM contains a Startup Wizard that lets you easily change settings to suit your needs.

Instances in which it might be necessary to change or make additional changes to the default

configuration include the following:

•To create administrative and Telnet passwords

Note We highly recommend that you change the administrative and Telnet passwords from their

default settings to secure the administration of your PIX Firewall.

•To configure Point-to-Point Protocol over Ethernet (PPPoE) or a static IP address for an outside

interface

•To configure VPN and Auto Update features

8PDM Startup Wizard

The PIX 501 contains an integrated configuration

utilitycalledCiscoPIXDevice Manager(PDM).PDM

is a web browser-based configuration tool designed to

help you set up, configure, and monitor the

PIX Firewall. PDM is preinstalled on the PIX 501.

To access PDM, make sure JavaScript and Java are

enabled in your web browser. For best performance,

we recommend that you use Microsoft Internet

Explorer 5.5 or a higher release. Refer to the Cisco

PIX Device Manager Installation Guide for more

information on the operating system and Web

browser environments supported by PDM.

PDM version 2.0 and higher releases include a Startup Wizard for initial configuration. Follow these steps

to load PDM and use the Startup Wizard:

Step 1 Use an Ethernet cable to connect your PC to one of the four switched inside ports (numbered

1 through 4) on the rear panel of the PIX Firewall.

Step 2 Configure your PC to use DHCP (to receive an IP address automatically from the

PIX Firewall) or assign a static IP address to your PC by selecting an address out of the

192.168.1.0 network.

Note The inside interface of the PIXFirewall is assigned 192.168.1.1, so choose a different

IP address.

Step 3 Check the LINK LED to verify that your PC has basic connectivity to the PIX Firewall on one

of the inside ports (1 through 4).When connectivity occurs, the LINK LED on the front panel

of the PIX Firewall lights up solid green.

Step 4 To access the Startup Wizard, use aPC connected to one of the PIX Firewall switch portsand enter

the URL https://192.168.1.1/startup.html into your browser.

Note It is very important to enter the “s” in “https://192.168.1.1,” which indicates

a secure connection. If you enter “http://192.168.1.1” without the “s” in

“https,” you cannot access the PIX Firewall.

Step 5 Accept the certificates and follow the instructions in theStartup Wizard. For online help,click

the Help button at the bottom of the Startup Wizard window.

9Alternative Ways to Access the PIX 501

You can use a serial terminal emulator from a PC or workstation connected to the Console port for

local administrative access.

You can also use PDM or a console to configure Telnet access to the PIX Firewall. By default, Telnet

access is not permitted. To Telnet to the PIX Firewall from the outside perimeter of the firewall,

configure an outside IP address and IPSec for a secure Telnet session. For more information, refer to

the Cisco PIX Firewall and VPN Configuration Guide.

Follow these steps to connect a console for local administrative access:

Step 1 Plug one end of the console cable adapter (29-0810-01) into a standard 9-pin PC serial port.

Step 2 Plug one end of the blue console cable (72-1259-01) into the console cable adapter.

Step 3 Plug the other end of the blue console cable into the Console port.

Step 4 Configure the PC terminal emulation software or terminal for 9600 baud, 8 data bits, no

parity, and 1 stop bit.

Refer to the Cisco PIX Firewall and VPN Configuration Guide for information about how to use the

command-line interface (CLI).
