Description of the problem

The previous host version of OSN1500 device V100R009 cannot query the fan speed. A Huawei OSN1500 transmission device fan reports a TEMP_OVER alarm, and returns Unregistered command when querying the fan speed through the :cfg-get-fanspeed command.

Alarm Information

TEMP_OVER.

Unregistered command

Processing

Query the "OptiX OSN3500_OSN2500_OSN1500 V100R003 and 7500V100R001 Command Line Manual", 5.36.13.XX (V1R3) or above version of the host can support this command, the host version of this network element is 5.36.13.47P01, the version conditions are met, check the version matching table. BIOS, ExtBios, FPGA, etc. are all matching, suspecting that the host is faulty, but querying several other OSN1500 network elements with the same OSN1500 version, the results are the same, and the commands :cfg-set-fanspeed, cfg-get-faninfo also return the Unregistered command.

Root Cause

1. The host version is low and does not support the command;

2, Mismatch of host software, BIOS, ExtBios, FPGA, etc. leads to errors;

3, host failure.

Suggestions and Summary

The relevant data is returned to the R&D for analysis with the result that Huawei OSN1500B transmission equipment does not support the query of fan speed in this version, and the host version V1R9 and later versions support it.
