4 Plan the Installation
Decide how you are going to configure the Cisco S170 Web
Security Appliance within your network.
The Cisco S170 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 To monitor true client IP addresses, the L4 traffic
monitor should always be configured inside the firewall
and before NAT (Network Address Translation).
5 Install the Appliance in a Rack
Install the Cisco S170 Web Security Appliance using either the
slide rails or fixed rack mount brackets. For information about
these installation options, see the Cisco 170 Series Hardware
Installation Guide.
Appliance Placement in a Rack
• Ambient Temperature—To prevent the 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 appliance.
• Mechanical Loading—Be sure that the appliance is level
and stable to avoid any hazardous conditions.
