HOME / Huawei switches do not show optical ports - Umele Photonics & Micro-Optics Europe
For example, if a non-XGE optical module is installed on an XGE port, the rate of the optical module does not match the port rate. In this case, replace the current optical module with a supported optical
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
Problem: All optical ports cannot be connected, and the indicator lights are not on. Solution: To solve this problem, you can follow these steps: Check if the fiber and optical modules
When connecting two devices, check whether optical modules match optical interfaces, whether optical modules match fiber models, and whether optical modules and fibers are connected correctly.
If a message is displayed, indicating that the optical module is not in position, remove and then properly insert the optical module. If the auto-negotiation mode is used but the interface cannot go Up, set the
As soon as the port speed is changed, the name of the ports change from 100GE to 40GE. The QSFP28 cables, which was accepted in the 100GE modus, wasn''t be recognized.
If there is a Huawei logo on the label, the optical module has been certified for Huawei data center switches. If not, send the model of the optical module to technical support personnel.
This facilitates optical module management and maintenance. To avoid these alarms, disable the alarm function for optical modules that are not certified for Huawei data center switches.
In this post, we will explore the top 5 Huawei display commands that can make your daily tasks easier and improve your understanding of what is happening behind the scenes.
Here is an example on how to query or display optical power of an interface in a Huawei Router. This is tested using NetEngine40E Universal Service Router or NE40E running version 8.x OS. display
To determine whether optical modules delivered for Huawei switches before July 1, 2013 are certified ones, contact Huawei technical support. If your optical modules are delivered after July 1, 2013, use
Huawei switches using non-certified optical module may not be able to read the information, can not guarantee the accuracy of the information read, recommend the use of Huawei certified optical
When connecting switches through optical ports, pay attention to the following points: The optical modules used on both ends must have the same wavelength.
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 switches do not support cards but downlink ports on the switch panel can be used as stack ports, these downlink ports can be used for stacking, and uplink ports can be connected to an uplink network.
Therefore, non-Huawei-certified switch optical modules are not recommended. When a non-Huawei-certified switch optical module is used, the following problems often occur: The optical module cannot
If the problem is not caused by the optical modules, fibers, or intermediate device, connect the switch to another interface or replace the switch to check whether
