CSG SIP Communications Gateway
Installing the Hardware
1. Connect an Ethernet cable connected to your network to the Network port on the back of the CSG.
2. Connect an Ethernet cable an IP Phone port. This will be used during the initial configuration of the
CSG.
3. Connect the provided power supply to the unit’s DC connector. The unit immediately receives
power once you connect a power source to it.
4. When the unit completes the boot process, the left-most eight LEDs indicate how the analog ports
are configured. A red light indicates the port is FXO, and a green light indicates the port is FXS. If
the light for a port is off, the port is not installed.
5. Connect telephones to the analog ports that are configured as FXS ports and connect phone lines to
the analog ports that are configured as FXO ports. If you are using the CSG-500, you can skip this
step.

The analog port configuration is selected when purchasing your CSG unit.
If you are using the CSG-544, do NOT connect analog ports 1-4 to a phone line.
Since both the FXS ports and the phone lines supply power, the hardware could
sustain damage. This damage is not covered under the AMX standard warranty.
