Hardware replacement procedures

  • Replacing a power supply
    Replacing a power supply (PSU) involves disconnecting the target PSU from the power source, unplugging the power cable, removing the old PSU, installing the replacement PSU, and then reconnecting the replacement PSU to the power source.
  • Hot-swapping a fan module
    To swap out a fan module without interrupting service, you must perform a specific sequence of tasks.
  • Replacing the controller module
    You must review the prerequisites for the replacement procedure and select the correct one for your version of the ONTAP operating system.
  • Replacing a DIMM
    You must replace a DIMM in the controller module when your system registers an increasing number of correctable error correction codes (ECC); failure to do so causes a system panic.
  • Replacing an NVDIMM
    You must replace the NVDIMM in the controller module when your system registers that the flash lifetime is almost at an end or that the identified NVDIMM is not healthy in general; failure to do so causes a system panic.
  • Replacing the boot media
    The boot media stores a primary and secondary set of system (boot image) files that the system uses when it boots.
  • Replacing the real-time clock battery
    You replace the real-time clock (RTC) battery in the controller module so that your system’s services and applications that depend on accurate time synchronization continue to function.
  • Replacing a PCIe or mezzanine card
    To replace a PCIe or mezzanine card, you must disconnect the cables and any SFP and QSFP modules from the cards, replace the failed PCIe or mezzanine card, and then recable the cards.
  • Replacing the NVDIMM battery
    To replace the NVDIMM battery, you must remove the controller module, remove the battery, replace the battery, and then reinstall the controller module.
  • Replacing the caching module
    You must replace the caching module in the controller module when your system registers a single AutoSupport (ASUP) message that the module has gone offline; failure to do so results in performance degradation.
  • Replacing the chassis
