HOME / Huawei optical module firmware flashing - Umele Photonics & Micro-Optics Europe
Have you ever experienced: the network cable in the computer room suddenly breaks in the middle of pulling, and the fiber optic interface does not match and you stare blankly; temporary
This is a modified transceiver that we can use for non-disassembly flashing. The tricky part here is that the bootdelay in the uboot environment variables is set to 0, so we must
Furthermore, PON cards or modules can only interconnect with Huawei''s equipment due to proprietary mechanisms. The rule is: port mode, RTU license, optical module, and the
Displaying Optical Module Information You can use the display commands to view information about the optical module on an interface, including conventional information, manufacturing information, and
To upgrade the modem on an interface card, run the module-upgrade transport-dcm slot slot-id module module-id directory command. The upgrade file name of an interface card is the
Usage Guidelines The display pon-transceiver interface pon command output includes the optical wavelength, identifier, transmission distance, version, bias current, voltage, and various alarm
Follow these guidelines when replacing an optical module: Wear an ESD wrist strap or gloves when replacing the cables. Ensure that the new optical module has the same center wavelength and
Use the idle optical module on the storage device to exchange with PO and check whether the fault is rectified. If the fault persists, it indicates that the optical module is not faulty. If
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 interface GigabitEthernet x/x/x command to
An Optical Module Has Normal Transmit Power but Many Packets Are Dropped on the Port Due to Bit Errors Use an optical power meter to check whether the receive power of the optical module is in the
Flash the firmware image to image0 or image1 via SSH or via TTL serial as usual. After flashing, it is absolutely necessary to connect to the SFP via telnet using the IP 192.168.1.10:
When certifying an optical module, Huawei comprehensively verifies the functions of the optical module to ensure the optical module quality. The functions include the installation and removal, transmit and
Services on the device are affected when the optical module is removed and inserted, or the device is restarted or upgraded. It is recommended that customer''s permission be obtained before performing
Select a product series ofOptical Accessto get manuals & documentation of Product Instruction, Installation/Upgrade, Configuration/Commissioning, Operation/Maintenance,Fault Management,
Due to an outbreak in Zhuhai, I returned home from school and naturally completed the documentation at home. Initially, I was inspired to start tinkering after reading the article MA5671A
Procedure Check whether the optical modules have been certified by Huawei. Devices must use optical modules certified by Huawei. Those that are not certified by Huawei cannot ensure service reliability,
The optical module installed on the optical interface is not certified for Huawei data center switches. The optical module type does not match the optical fiber type.
