The rfru command is used to display the fru information.


rfru frutype Frunum






Fru type.

The value is "0", "1", "3", "7", "10", "11", "16", "29", or "31", a hexadecimal value is also supported. where:

  • "0": Bbu type.

This value is only valid in x86 devices integrating disks and controllers.]

  • "1": EAR type.
  • "3": Cbu type. [Note:This value is only valid in ARM devices integrating disks and controllers.]
  • "7": Board type.
  • "10": Power type.
  • "11": iocard type. [Note:This value is invalid in disk enclosures.]
  • "16": Back board type.
  • "29": Fan type (17,500 spd). [Note: This value is invalid in the 4 U high-density disk enclosure with 75 disk slots.]
  • "31": Unified fan type. [[Note: This value is only valid in the 4 U high-density disk enclosure with 75 disk slots.


Number of the fru component whose information is to be obtained.


Multiple fru components of the same fru type may exist in the environment. If the value of Frunum is greater than the actual number of fru components, no information will be displayed.

This parameter can be obtained by querying the FRU quantity in the system. A hexadecimal value is also supported.


serial port mode

Usage Guidelines



Run the "rfru 0 0" command to display the information about fru whose frutype and Frunum are both 0.
