What is FRU (Field Replaceable Unit)?
| F.A.Q. • SupportWhat is FRU (Field Replaceable Unit)?
In the context of DMI (Desktop Management Interface), FRU (Field Replaceable Unit) refers to specific information about hardware components that can be replaced by the user or a technician. DMI is an interface used for collecting and managing information about computer hardware. FRU Information in DMI is detailed data describing these replaceable components. This information may include:
- FRU Identifier: A unique identifier assigned to each replaceable component.
- Component Description: The name and description of the component, e.g., "500W Power Supply" or "8GB DDR4 Memory Module."
- Serial Number: A unique serial number for the component.
- Manufacturer: The name of the component's manufacturer.
- Production Date: The date when the component was manufactured.
- Component Status: Information about the status of the component, e.g., "Functional" or "Defective."
For example:
This information is stored in NVRAM (Non-Volatile RAM) or EEPROM (Electrically Erasable Programmable Read-Only Memory) on the motherboard or on the component itself. This allows IT management systems to automatically identify and track the status of individual server components, facilitating hardware management and maintenance.
In short, FRU in the context of DMI refers to information about replaceable hardware components that are managed and monitored through the DMI interface.
