Stage Symptom

Suspected Cause and Action To Be Taken

The POWER lamp in the front access

area of the Gateway is not lit in green.



Check if the power cord plug is firmly inserted

in the outlet.



Try connecting any other device to the outlet to

see if the power is supplied to the outlet.



If the power cord is plugged to a service outlet

of any other device such as PC, plug the power

cord directly to a mains outlet. Otherwise,

disconnection of power to the service outlet

also disconnects power to the Gateway.



Check if the power cord is free of damage. If

you find any damage, immediately unplug the

power cord from the outlet.

The ALARM lamp in the front access

area of the Gateway is lit in red.

The Gateway is in error. Restart the Gateway by

unplugging and plugging the power cord with an

interval of 10 seconds or longer between

unplugging and plugging.

When the WAN port in the rear access

area of the Gateway is in use, the WAN

lamp in the front access area is not lit in

green or not blinking in green.



Check if both the Gateway and the WAN side

equipment are turned on.



Reconnect the LAN cable between the WAN

port of the Gateway and the LAN port of the

WAN side equipment until you hear a click from

each port connection.
