Problem DescriptionA bureau OSN3500 new expansion of a N4EGS4 single board, single board expansion up, the single board can be normal work, network management can also be added to the normal, is the STATE light red. After configuring the service, the board does not report any alarms.
Host version is: 18.50P01
Host version is: 18.50P01
Alarm informationNone
Processing1, due to the R8 host does not support the N4EGS4 single board, in the network management to create a N3EGS4, this is correct, the single board version is also with the host supporting.
2, replaced a single board, or the same phenomenon.
3, replaced the slot or the same phenomenon.
4, reversing the main control board or the same phenomenon.
5, after on-site verification, found that the N4EGS4 single board configuration of the Gigabit power module, but the host does not support the Gigabit power module, the host will be upgraded to R9, the problem is solved.
6、If you can not upgrade to R9 version, you can only replace the electric module with an optical module.

Root Cause 1、Single board failure
2、Slot failure
3、Fault fault
4、Single board specification host does not support
2、Slot failure
3、Fault fault
4、Single board specification host does not support
Recommendations and SummaryWhen encountering this strange phenomenon, you can consider whether the version of the single board matches or not, and whether some specifications of the single board are not supported by the host. It is recommended that R&D should report some alarms to indicate that the module is not correct in this scenario.
In addition, whether the EGS4 board is configured with an optical module or an electrical module can be confirmed by checking the manufacturing information of the board.
