Power LED Is Off
If the Power and other LEDs are off when your modem router is turned on:
• Check that the power cord is correctly connected to your modem router and the power
supply adapter is correctly connected to a functioning power outlet.
• Check that you are using the power adapter supplied in the package with this product.
If the error persists, you could have a hardware problem. Contact technical support.
Power LED Is Red
When the modem router is turned on, it performs a power-on self-test, during which time the
Power LED turns red. If the Power LED does not turn green within a minute or so or if it turns
red at any other time during normal operation, there is a fault within the modem router.
