Huawei ONT LED Status & it’s Function
Huawei ONT LED Status & it’s Function:
There are many LEDs in Huawei ONT. Such as CATV, WPS, WLAN, USB, TEL1 – TEL2, LAN1 – LAN4, LOS/PON, POWER. We can simply troubleshoot by follow Huawei ONT LED Status. So at first we need to introduce with every ONT LEDs & it’s function. So let’s go…….
In the preceding table, if the LED status is marked “Blinking” but the frequency is not specified, it indicates that the blinking frequency of the LED is determined by the data traffic transmitted.
Description of LEDs:
PON and LOS are GPON LEDs. The status of PON and LOS reflects the connection between GPON terminal and the optical line terminal (OLT). The following table describes the status of the PON and LOS LEDs.
When the LEDs are in the states as described in No. 5, that is, the OLT detects that the device is a rogue ONT, rectify the fault in time and replace the rogue ONT.
