[Background Information]
TNH2SL1D, TNH2SP3D, and TNH2PL3T boards are developed based on OptiX OSN 550 V100R003 and are used on OptiX OSN 500 V100R002 to replace TNH1SL1D, TNH1SP3D, and TNH1PL3T boards.
TNH2 boards are applied to OptiX OSN 500 V100R002 using the hardware independence technology. Software of OptiX OSN 500 earlier than V100R002SPC305 does not contain the driver for TNH2 boards. The NEs dynamically load the driver stored in the flash memory of TNH2 boards. Then the NEs use the interface that is used to access the driver of TNH1 boards to access the driver of the TNH2 boards. In this case, TNH1 boards can be replaced by TNH2 boards without changes on the NE software.
The driver stored in the flash memory of TNH2 boards is called the hardware independent driver.
[Problem Description]
Trigger conditions:
The OptiX OSN 500 version is earlier than V100R002C01SPC305 (5.62.02.16). A TNH2SL1D board (independent driver version: 120) or TNH2SP3D board (independent driver version: 120) is installed.
Symptom:
After a TNH2SL1D board is installed in the extended slot of the NE, the board fails to go online and the physical board cannot be queried on the NMS. After a TNH2SP3D board is installed, the NE becomes unreachable. After the TNH2SL1D board or TNH2SP3D board is installed on an OptiX OSN 500 V100R002C01SPC305 (5.62.02.16) or later, the board goes online normally.
Identification method:
This issue is triggered when both of the following conditions are met:
1. The OptiX OSN 500 version is earlier than V100R002C01SPC305 (5.62.02.16).
:ver
BIOS 8.26.21T01 20131122 14:00:56 inactive

2. The independent driver version of the TNH2SL1D board or TNH2SP3D board is 120.
If the board is installed in slot 3, the address for querying the independent driver version is 0x53460090. If the board is installed in slot 4, the address for querying the independent driver version is 0x53C60090.
For the TNH2SL1D board, the three digits after tnh2slxd.hwx indicate the independent driver version.

[Root Cause]
If the NE version is earlier than V100R002C01SPC305 (5.62.02.16), the NE software does not contain the driver for the TNH2SL1D or TNH2SP3D board. The NE must load the independent driver from the flash memory of the board. If the independent driver version of the TNH2SL1D or TNH2SP3D board is 120, the driver interface defined by the driver is different from that defined by the NE. Therefore, the board fails to go online, or NE tasks are suspended.
[Impact and Risk]
After a TNH2SL1D board is installed, the board fails to go online. After a TNH2SP3D board is installed, the NE becomes unreachable.
[Measures and Solutions]
Recovery measures:
Remove the TNH2SL1D or TNH2SP3D board.
Workarounds:
Before installing a TNH2SL1D or TNH2SP3D board, upgrade the OptiX OSN 500 to V100R002C01SPC305 (5.62.02.16) or later.
Preventive measures:
Upgrade the independent driver or the OptiX OSN 500 software.
1. Upgrade the independent driver:
Upgrade the independent driver of the TNH2SL1D board to version 131, and that of the THN2SP3D board to version 130. For details, see the attachment《OptiX OSN 500 Independent Driver Upgrade&Downgrade Guide》.
2. Upgrade the OptiX OSN 500 software:
Upgrade the NE software to V100R002C01SPC305 (5.62.02.16) or later.
