SSG 140 Series Hardware Installation and Configuration Guide
24 Connecting the Device to a Network
Connecting Ethernet Ports
To establish a high-speed connection, connect the provided Ethernet cable from the
Ethernet port marked 0/0 on an SSG 140 device to the external router. The device
autosenses the correct speed, duplex, and MDI/MDIX settings.
Connecting Serial (AUX/Console) Ports
You can connect to the untrusted network with an RJ-45 straight-through serial
cable and an external modem.
Connecting PIMs
This section explains how to connect the device PIMs to an untrusted network.
To connect the PIMs to a device, 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.
3. Arrange the cable as follows to prevent it from dislodging or developing stress
points:
a. Secure the cable so that it is not supporting its own weight as it hangs to
the floor.
b. Place any excess cable out of the way in a neatly coiled loop.
c. Use fasteners to maintain the shape of the cable loops.
To configure the PIMs, see “PIM Configuration” on page 35.
WARNING: Make sure that you do not inadvertently connect the Console, AUX, or
Ethernet ports on the device to the telephone outlet.
WARNING: To reduce the risk of fire, use only 26 AWG or larger UL listed or CSA
certified telecommunication line cord.
NOTE:For ISDN U interface support, an external NT-1 device is required.
