Troubleshooting
Synapse User's Guide
Probable Cause
There is no power to the
device.
The Ethernet cable is
unplugged.
The Gateway needs time to
restore service.
The PSTN line is not in the
correct jack.
Corrective Action
Ensure the AC plug is plugged into an electrical outlet not
powered by a wall switch.
Verify that the AC power outlet has power, such as
plugging in some other AC device. If nothing works,
contact an electrician or use another power outlet.
Verify that the DC plug is plugged into the power jack
marked on the front of the Gateway.
Ensure that one end of the Ethernet cable is plugged into
the port marked LAN on the front of the Gateway and that
the other end is plugged into your office LAN.
Confirm that the Ethernet port light next to the Ethernet
port on the Gateway is green. If it is not, unplug the cable
and plug it in again.
There may be a problem with the office network. Check if
other network devices, such as computers, are
communicating with the network. If not, then contact your
IT administrator.
Allow at least 30 seconds for the Gateway to boot up
again after a power failure.
Make sure there is a PSTN line plugged into Line 4.
Make sure an analog phone is plugged into the bypass
jack (using a modular line cord).
