Troubleshooting
LED Symptom Action
All LEDs are on. If the LEDs remain on after ten minutes, the RTU is not
functional. Contact the NSP.
ALM LED remains
on. The power-on self-test may have failed. Unplug the unit and
reapply power. If the alarm light is still on, contact the NSP.
ALM and TST
LEDs are blinking. Firmware download may be in progress. If firmware download
is not in progress or the LEDs remain on after ten minutes,
contact the NSP.
DSL LED is off. Verify that the DSL cable is securely installed on both ends.
If the problem continues, contact the NSP.
DSL LED continues
to blink after the
power-on self-test. The RTU is attempting to establish the DSL link or adjusting
the rate of the DSL line due to line conditions. If the DSL LED
continues to blink for more than ten minutes, contact the NSP.
DSL LED is on and
there is no data
transmission. The DSL link has been established but there is no data
transmission. Verify the Ethernet connection. If the problem
persists, contact the NSP.
DSL and Ethernet
LEDs are on and
there is no data
transmission. The DSL and the Ethernet links have been established but
there is no data transmission. If the problem continues, contact
the NSP.
Ethernet LED is off. Verify that the Ethernet 10BaseT cable is securely installed at
both ends, and that a PC is connected and powered on.
Verify that the correct crossover cable is installed. Refer to
Installing the Hotwire 5216 RTU , page 8.
PWR LED is off. Check that the power cord is securely installed on both ends.
If no LEDs are on, the power supply may be defective. Test the
outlet to verify power. If the problem persists, contact the NSP.
If other LEDs are on, the PWR light may be burned out. Unplug
the unit and reapply power; watch all LEDs during the
power-on self-test to verify that the PWR LED is functioning.
TST LED is on. A test initiated by the NSP may be active. Wait five minutes. If
the TST LED does not go off, contact the NSP.
