Distinguishing CRUs and FRUs

Distinguishing CRUs and FRUs

This chapter describes how to replace customer replaceable units (CRUs) and field replaceable units (FRUs).

CRU

CRUs are components that users can replace at the deployment site by referring to the operation guide.

  • Operators: customers
  • Replaceable modules: power modules, BBU modules, fan modules, disk modules, expansion modules, and optical modules

Customers are allowed to replace CRUs, but are prohibited from replacing other components to prevent personal injury and device damage.

FRU

FRUs are components that users can replace at the deployment site by referring to the operation guide.

  • Operators: Huawei technical support engineers and maintenance engineers as well as technical support engineers and maintenance engineers certificated by Huawei
  • Replaceable modules: controllers, interface modules, system subracks, and cables

To effectively check software and hardware status and ensure the successful replacement of an FRU, use the FRU replacement tool of OceanStor SmartKit to guide you through the replacement.
