Figure 21: Basic Cabling Example
Connecting a Device Using Ethernet Ports
To establish a high-speed connection, connect the provided Ethernet cable from the
Ethernet port marked 0/2 (ethernet0/2, which is in the Untrust security zone) on an
SSG 500M Series device to the external router. The device auto-senses the correct
speed, duplex, and MDI/MDIX settings.
Connecting a Device Using Serial (AUX) Ports
You can connect to the untrusted network with an RJ-45 straight through serial
cable and external modem.
Connecting PIMs to an Untrusted Network
You can connect Ethernet and WAN PIMs to an untrusted network. To connect the
PIMs to a network, perform the following steps:
1. Have ready a length of the type of cable used by the interface.
2. Insert the cable connector into the cable-connector port on the interface
faceplate.
