Step 2: Properly fix the SMG analog gateway.
If you do not need to place the gateway on the rack, simply fix the 4 rubber foot pads. Otherwise,
you should first fix the 2 angle brackets onto the chassis and then place the chassis on the rack.
Step 3: Connect the power cord.
Make sure the device is well grounded before you connect the power cord. Check if the power
socket has the ground wire. If it doesn’t, use the grounding stud on the rear panel of the device
(See Figure 1-3) for earthing.
Step 4: Connect the network cable.
Step 5: Connect the telephone line. The line from PSTN should be connected to FXO port
(port with red LED flashing); the line from station should be connected to FXS port (port
with green LED flashing).
