Important Do not interrupt this process after you begin.

Ensure that the server is in the service processor standby state. The service processor standby state is indicated when the server is powered off, and when the power-on LED on the control panel is flashing slowly.
Insert the USB flash drive into one the following USB ports: One of the two black USB ports (P1-C1-Tx) on the rear of a rack-mounted or stand-alone system.Note The blue USB 3.0 ports are for logical partition. For additional information, see the Location Codes section in your host model's service guide. The firmware level is loaded automatically. The level of firmware on the USB flash drive will be installed on both the P and T sides of the service processor assembly.The following checkpoints are posted on the control (operator) panel during the installation of the firmware:
- C100B100: The firmware image is being unpacked.
- C100B101: The firmware image is being installed on a side of the flash.
- C100B102: The firmware image is being installed on the other side of the flash.
- C100B103: The firmware installation has been completed successfully.Notes
  - After inserting the USB flash drive, the initial checkpoint code might take about 5 minutes to display on the control panel, and might be displayed for about 10 minutes.
  - After the initial checkpoint is passed, the secondary checkpoint code might take about 5 minutes to display on the control panel, and might be displayed for about 10 minutes.
  - The final checkpoint code might be displayed on the control panel for about 10 seconds.
  Note If a C100B104 code is displayed, the firmware installation has failed. Perform the following steps:
  1. Ensure that the USB flash drive contains the firmware fix. If necessary, copy the firmware to the USB flash drive again.
  2. Retry the task with another USB flash drive.
  3. If necessary, replace the service processor assembly.

After checkpoint C100B103 is displayed on the control panel, you can safely remove the USB flash drive.
