Requirements for replacing a power canister

If you plan to replace a power supply, keep the following requirements in mind.

• You have a replacement power canister that is supported for your controller shelf or drive shelf model.
• You have one power canister that is installed and running.
• You have an ESD wristband, or you have taken other antistatic precautions.
• You can replace a power canister while your storage array is powered on and performing host I/O operations, as long as the following conditions are true:

  • The other power canister in the shelf has Optimal status.
    Note

    While you perform the procedure, the other power canister supplies power to both fans to ensure that the equipment does not overheat.
  • The OK to remove field in the Details area of the Recovery Guru in ThinkSystem System Manager displays Yes, indicating that it is safe to remove this component.
    Attention

    If the second power canister in the shelf does not have Optimal status or if the Recovery Guru indicates that it is not OK to remove the power canister, contact technical support.
