Plan the Installation
Plan the Installation
Decide how you are going to configure the Cisco Web Security Appliance within your network.
The Cisco Web Security Appliance is typically installed as an additional layer in the network between
clients and the Internet. Depending on how you deploy the appliance, you may or may not need a Layer
4 (L4) switch or a WCCP router to direct client traffic to the appliance.
Deployment options include:
•Transparent Proxy – Web proxy with an L4 switch
•Transparent Proxy – Web proxy with a WCCP router
•Explicit Forward Proxy – Connection to a network switch
•L4 Traffic Monitor – Ethernet tap (simplex or duplex)
–
Simplex Mode: Port T1 receives all outgoing traffic, and port T2 receives all incoming traffic.
–
Duplex Mode: Port T1 receives all incoming and outgoing traffic.
Note See “Connect to the Appliance” section on page 7 for more information about individual ports on the
appliance.
Note To monitor true client IP addresses, the L4 traffic monitor should always be configured inside the
firewall and before NAT (Network Address Translation).
If your installation includes multiple Cisco Web Security Appliances (S-Series) or Cisco Email Security
Appliances (C-Series), you may want to also use a Cisco Content Security Management Appliance
(M-Series) to manage them, as show in the following network diagram:

Temporarily Change Your IP Address for Remote Access
Temporarily Change Your IP Address for Remote Access
To remotely configure the appliance using the network connection, you must temporarily change the
IP address of your computer.
Note Make a note of your current IP configuration settings as you will need to revert to these settings after
you finish the configuration.
Alternatively, you can use the serial console to configure the appliance, without changing the IP address.
If you use the serial console, see Connect to the Appliance, page 7.
Temporarily Change Your IP Address on Windows
Note The exact steps depend on the version of your operating system.
Procedure
Step 1 Connect your laptop to the primary Management Port (labeled M1) using the cross over or Ethernet cable
included in the system box. The Cisco Web Security Appliance uses the M1 Management port only. See
“Plan the Installation” section on page 5.
Step 2 Go to the Start menu and choose Control Panel.
Step 3 Double-click Network and Sharing Center.

Connect to the Appliance
Note The connection diagram in each topic shows the default configuration using a management computer
connected to your private network. Your deployment may vary depending on your basic logical network
connectivity, ports, addressing, and configuration requirements.
Cisco S195 Appliance
Step 1 Plug one end of the straight power cable into the power supply on the back panel of the appliance.
Note It is optional to order a separate power cable and connect to the second power supply at the back
panel of the appliance for redundancy.
Step 2 Plug the other end into an electrical outlet.
Step 3 Plug the Ethernet cables into the appropriate ports on the back panel of the appliance.
•The proxy ports are labeled P1 and P2.
–
P1 only enabled: When only P1 is enabled, connect it to the network for both incoming and
outgoing traffic.
–
P1 and P2 enabled: When both P1 and P2 are enabled, you must connect P1 to the internal
network and P2 to the internet.
•The traffic monitor ports are labeled T1 and T2.
–
Simplex tap: Ports T1 and T2; one cable for all packets destined for the internet (T1) and one
cable for all packets coming from the internet (T2).
–
Duplex tap: Port T1; one cable for all incoming and outgoing traffic.
Step 4 Connect your laptop to the Management port (M1) using the Ethernet cable included in the system box.
Step 5 Power up the appliance by pressing the On/Off switch on the front panel of the appliance. You must
wait 10 minutes for the system to initialize each time you power up the system. After the appliance
powers up, a solid green light on the front panel indicates that the appliance is operational.
1 Management port (M1) - (192.168.42.42) 2 Management computer (192.68.42.43)
3 Traffic monitor port 1 (T1) 4 WAN modem
5 Internet

Connect to the Appliance
Caution 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.
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.
Step 6 See the AsyncOS for Cisco Web Security Appliances User Guide for further configuration.
