20 Blue Coat SG200 Series
Section B: Placing the SG200 into the Network
This procedure describes a typical scenario for placing the SG200 into your network. Use this procedure
for the following circumstances:
• You have already completed an initial configuration on the SG200.
• You are going to complete an initial configuration on the SG200 using a direct serial port connection or
a remote Web browser setup.
Because the appliance comes with a pass-through card, bridging is set up by default. You do not need to
set up a bridge between the two interfaces.
The following instructions are an example of a typical network scenario—placing the SG200 between the
LAN and a router or firewall connected to the WAN. If you do not know how to place the SG200 into your
own network, consult with your IT administrator. For less common network configurations, such as using
WCCP or a Layer 4 switch, refer to the
Blue Coat ProxySG Configuration and Management Guide Suite .
To Place the SG200 into the Network:
1
Connect the SG200 to the WAN—connect one end of an Ethernet cable (straight or crossover
depending on your network topology) to one of the SG200’s Ethernet ports (either one). Connect the
other end to the router or firewall connected to the WAN.
2
Connect the SG200 to the LAN—connect one end of an Ethernet cable (straight or crossover
depending on your network topology) into the other Ethernet port on the SG200. Connect the other
end to the LAN (such as a PC or a hub).
3
Verify that the network link is established by checking the network connection LEDs at the back of the
SG200. If the network connection is functioning, the left-hand LED on each connection glows green
(see Figure 2-2 on page 13).
If the network connection does not function, see “A Network Link is Not Established” on page 41.
Note: The SG200 Series is designed to fail open. For example, if the appliance loses power, it is
designed to allow network traffic to pass through its bridge ports. If you prefer the
appliance to fail closed and block all traffic in the event of a power loss, you must remove
the pass-through card. See
Removing the Pass-Through Card on page 47.
