# Update enclosure firmware

Select a new SPP and update the firmware for all hardware components in an enclosure. When setting a new firmware baseline for an enclosure, you have the option to update the:

- Enclosure only (OA firmware)

- Enclosure, logical interconnect, and the server profiles (OA, interconnect, and server firmware including iLO)

  | NOTE: If you update the enclosure, logical interconnect, and the server profiles, the previous firmware version stored in the server profile is replaced with the new firmware version. You can downgrade or reinstall the firmware using a force upgrade. When you set the `forceInstallFirmware` attribute to `false`, the firmware bundle that you select is applied regardless of what version is installed on the enclosure, logical interconnects, and server profiles.

### Prerequisites

- Minimum required session ID privileges: Infrastructure administrator or Server administrator

- A firmware bundle, also known as Service Pack for ProLiant (SPP), uploaded to the appliance
