If this optical module is not delivered from Huawei or is not customized for Huawei, replace it with a Huawei-customized optical module. Cause 2: Temperature of the installed optical
This article summarizes several solutions for using optical modules with switches and common problems encountered during usage, along with specific solutions.
Troubleshooting Optical Module Issues Symptom An optical port cannot go Up. The optical module cannot be properly identified and optical module information cannot be obtained. After
This document describes how to check the switch interface or port status and how to locate an interface physically down fault and restore the interface to the up state.Major causes of the interface physically
Symptom When a 10GE optical interface of a switch is connected to a remote device using a GE optical module, there is a possibility that the 10GE optical interface fails to go Up.
The following uses the Moduletek SFP-10G-LR module connected to a Huawei S6700 switch as an example to introduce how to read information of the connected optical module on a
For details about the optical modules supported by optical ports on switches, see "Appearance and Structure" of a specific switch model in the Hardware Description. The following figure shows the
I see LCM_EV_PFM_SEEPROM_READ_ERROR in the events and MOD_STATUS_ERRDOWN in the system log. 2022 Dec 1 17:04:19 spk-ptt-nexus-c9508-1
Execute the command, display transceiver diagnosis interface [ interface-type interface-number ], display optical transceiver diagnostic
Introduction This guide provides a structured approach to troubleshooting network link failures in AI data centers, specifically targeting issues where the link cannot up. Walking you from physical-layer
Optical Modules on the Local and Remote Devices Cannot Communicate Fault Description A switch is connected to a remote device through optical interfaces and optical fibers. The two optical ports are
CloudEngine 16800, 12800, 9800, 8800, 7800, 6800, and 5800 Series Switches Troubleshooting Guide (V100 and V200) Optical Interface Interconnection Is Abnormal on CE
Displaying Optical Module Information Context When the optical module on an interface is faulty, you can run the display commands to view information about the optical module.
If it is not a Huawei-certified optical module, replace it with a Huawei-certified optical module. If the optical module is installed on a GE port, run the display interfaceGigabitEthernet x/x/x command to
Check whether the optical module is Huawei-certified. If it is not certified by Huawei, replace it with a Huawei certified one. Remove and reinstall the optical module.
If optical modules that are not certified for Huawei data center switches are used on devices, the devices will generate a large number of alarms to prompt users to replace these optical
A Huawei S12708 switch experienced excessive fan spinning due to a faulty optical module. Replacing the module resolved the issue. This incident highlights the importance of
The optical module type does not match the interface configuration. If the optical module or card for the interface is replaced after the current configurations take effect and the new optical module or card
Replace the optical module and optical fiber preferentially. If a wavelength division multiplexing or transmission device exists on the link, remove the intermediate device to make the local and remote
