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

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.

9
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.

10
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).
