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.

S170_QSG.fm Page 7 Wednesday, March 13, 2013 10:23 PM

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.
