By default, numerous alarm messages will be generated when a non-original Huawei module is used. Huawei
Displaying Optical Module Information You can use the display commands to view information about the optical
Run the display transceiver verbose command to check the power of the optical module. Check whether the interface
Context You can set optical power alarm so that the device generates alarms if the transmit or receive power of an optical module
With hands-on experience in Huawei OLT and ONT configuration, U2000 NMS deployment, iMaster NCE-FAN Lite
Huawei Technical Support provides comprehensive solutions and assistance for managing and resolving issues related to Huawei
If neither transmit nor receive power alarms are displayed on the two ends but the two interfaces are still down,
Setting Optical Power Alarm Thresholds Context You can set optical power alarm so that the device generates alarms if the transmit
The device has two types of optical module power alarms: warning and alarm. A warning is reported when the difference between
You can configure the alarm thresholds for the power of optical modules to shield unnecessary alarms. To check alarm information,
If optical modules that are not certified for Huawei data center switches are used on devices, the devices will generate a large
Check “Alarm information” section for warnings, LOS Alarm means no inbound signal, execute display this to check
The device data bus is abnormal because of the data bus defects of the non-Huawei-certified optical module. Some non-Huawei
This article summarizes several solutions for using optical modules with switches and common problems encountered
Non-Huawei-certified switch optical modules may fail to work normally. If non-Huawei-certified switch optical modules
Check historical alarms. If many up/down alarms of the interface were generated for a long time, the interface status is unstable. You
When these optical modules are used on devices, the devices will also generate non-Huawei-certified optical module
ALM-3276800043 Indicates that the optical power exceeds the upper alarm threshold or falls below the lower alarm threshold 136196
Moduletek Laboratory has sorted out mainstream switch brands with customized compatibility restrictions, and
