Device Type (Component Type) ​

Change History ​

iBMC 4-segment versionRevision DateDescriptionRevised By
3.10.02.332024-06-01The component type 95 is added, which points to the optical module and is used to display the Redfish interface for data collection.Shi Junguo
3.15.06.032024-06-05The component type 96 is added to specify the main type of the event reported by the HDU(High-voltage Distribute Unit) alarm.Guan Mao Le
3.15.06.032024-06-05The component type 94 is added as the event body type reported by the module (HiAM) object alarm.Xu Junlin
3.17.01.072024-11-07The component type 97 is added, which is used as the event body type for NP board alarm reporting.Sun Yuanxing
5.06.00.012024-12-26The 0x19 power transfer board is reused. The naming differences are as follows:
A power transfer board is a device used to transfer electric energy from one power supply to another. It is usually used in wireless charging or power transmission systems. It can transfer electric energy from one source to another without using traditional wires or plugs.
A power adapter board is a device used to adapt the output voltage and current of a power adapter (such as a power plug) to the requirements of a specific device. It is usually used to convert an alternating current into a direct current, and provide the direct current for an electronic device to use.		Yuan Jia
5.08.00.012024-02-17The component type 98 is added, which is used as the event type reported by the LCN board.He Shijie 00873585
Not involved2025-05-19The component type 252=0xFC and Ascend software alarms (such as MindIE and MindCluster) are added.Cao Chengjian c00616303

iBMC V3: Fru Type and Component Type are defined in the same way. The exception part of Fru Type is separated.

Class and attribute: Fru.Type, Component.Type

Scenario ​

When information about a specified FRU is obtained through precise locating, the recommended obtaining mechanism is as follows: Run the Get Fruid Info command to obtain the FRU ID through the device_type=xx;group_id=xx;device_number=xx; parameter (xx is a hexadecimal value and is configured by the invoker. For example, the equipment personnel configure the FRU ID based on the BOM 0302 code). Then, query or set the electronic label and query the version information based on the FRU ID.

https://anytestlab.huawei.com/business/tuManage/detail?tuSolutionId=1000011600

Scenario 2:

1) Query the FRU types corresponding to all FRU IDs. 2) Find the FruId corresponding to the BCU/NPU and query information such as the UID based on the FruId.

Application scenario: (Query the component or FRU whose FruId is 0. The FRU whose FruName is BMC is preferred.)
For the Tianchi model, set FruId to 0 for the component whose FruName is BMC (FRU type is 26). The event body is chassisBMC/MotherBoard.For non-Tianchi models, set FruId to 0 for the component whose FruName is Mainboard (component type is 16).
