Urgency

Medium

Quick answer

On Vodafone's ZTE ZXHN F6600P ONT, the Internet light off means there is no active WAN session or IP address. Check the PON and LOS lights, restart with the Reset button for one second (settings are kept) and, if it stays off, call Vodafone.

Safety first

Stop and check this first

  • Holding the Reset button for more than 5 seconds factory resets the ONT and erases its configuration: only do it if Vodafone asks you to.
  • Do not open the casing and do not stare into the optical interface (PON port): the manual warns of possible eye injury.
  • Use only the included power adapter and do not extend its cable: the manual says the device will not work if you do.

Safe checks you can perform

  • Check the Power light
  • Read the PON and LOS lights
  • Restart without losing the configuration
  • Report the light states to Vodafone

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Remote connection check with Vodafone
  • Do not attempt this professional task: Vodafone technician visit

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Remote connection check with Vodafone

    What they doVodafone technical support checks your ONT's WAN configuration, the Internet session status and the IP address assignment for your line.

    They must show youthe session and IP status of your line in their system.

    In writingthe ticket number, the diagnosis and the action taken.

  2. Vodafone technician visit

    What they doIf the connection cannot be restored remotely, a Vodafone technician checks the ONT and the line at home, with an optical power reading and a line test from the exchange.

    They must show youthe optical power reading at the ONT and the line test result.

    In writingthe power value, the cause found and whether the ONT is replaced.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Check the Power light

    No special tools

    Who:
    you.
    How:
    look at the Power light: solid green means the device is on; if it is off, check the On/Off switch and that the original adapter is plugged in properly, with no extension on the power cable.
    Result that matters:
    ruling out the Internet light being off just because the device has no power.
    If Power is off:
    switch the device on and wait for all the lights to start.
    If Power is solid green:
    the device is on, continue with the fibre lights.
    Evidence to keep:
    photo of the front with all the lights.

  2. Read the PON and LOS lights

    No special tools

    Who:
    you.
    How:
    look at PON and LOS: PON solid green with LOS off means correct registration and correct optical power; PON blinking or LOS red points to a fibre problem, which is a different case.
    Result that matters:
    knowing whether the fault is in the fibre or only in the Internet connection.
    If PON solid green and LOS off:
    the fibre is fine and the session or IP is missing.
    If PON blinks or LOS is red:
    check the fibre cable without bending it or looking into the connector, and contact Vodafone.
    Evidence to keep:
    photo of the PON, LOS and Internet lights.

  3. Restart without losing the configuration

    No special tools

    Who:
    you.
    How:
    with the device on, hold the side Reset button with a needle for one second: the manual says this restarts it and the current configuration is not lost.
    Result that matters:
    the Internet light turning solid green once the session and IP are back.
    If Internet solid green:
    the connection works again.
    If it stays off:
    do not try long presses and call Vodafone.
    Evidence to keep:
    time of the restart and the Internet light state afterwards.

  4. Report the light states to Vodafone

    No special tools

    Who:
    you, with Vodafone technical support.
    How:
    explain that Power and PON are solid green, LOS is off and the Internet light stays off after a restart, so they check the session and WAN configuration of your line.
    Result that matters:
    Vodafone checking the part of the connection you cannot touch.
    If they fix it remotely:
    the Internet light stays solid green.
    If they cannot fix it remotely:
    ask for a ticket number and a technician visit date.
    Evidence to keep:
    ticket number and photos of the lights before and after.

What it means

The ZTE ZXHN F6600P manual published by Vodafone (in Spanish) says the Internet light off means device powered off, no WAN interface configured, session disconnected by either end, or no IP address on the interface (no static IP or after a DHCP release). It is an Internet connection fault, above the GPON fibre link shown by the PON and LOS lights. Solid green means connectivity with an IP assigned. The light alone never proves the ONT is faulty.

Symptoms and causes

Probable causes · in order

  • Internet session disconnectedCommon

    According to the manual, the light goes off if the session was disconnected at the request of either end, the router or the Vodafone network.

    Evidence: ZXHN F6600P GPON ONT Manual de Usuario (Vodafone España)

  • No IP address assignedPossible

    The manual includes an interface with no IP address: no static IP configured, or because a DHCP release of the IP has taken place.

    Evidence: ZXHN F6600P GPON ONT Manual de Usuario (Vodafone España)

  • WAN interface not configuredPossible

    The light also stays off if no WAN interface is configured on the device, a configuration that belongs to Vodafone.

    Evidence: ZXHN F6600P GPON ONT Manual de Usuario (Vodafone España)

  • Device switched offLess common

    The first cause in the table is the simplest: the device is off, and then the Power light is off too, which shows solid green when on.
