Hi Friend,
These equipments came into EOM and EOS. Huawei no longer provides firmware update support for them.

End of Marketing (EOM): The EOM date is the date from which the acceptance of the POs for new deployments and capacity expansions will be rejected. The product is no longer sold after this date. Note: Capacity expansion orders of storage products can still be accepted for two years after EOM for new sites.
End of Service and Support (EOS): After the EOS date, all services will be discontinued, and customers will not be able to use any service for this product, such as service hotlines.
Thank you
