System firmware updates

This section provides information and instructions for updating the system firmware. You may need to
perform these steps if you are installing an option or if your support representative has instructed you to
update your firmware.
Downloading the firmware update image and update instructions from the Web is preferred.
Always check the NAS Gateway 500 Support Web site for the latest firmware images and update
instructions. The Web address is: http://www.ibm.com/servers/storage/support/download.html.
Notes:
1. Firmware update installation is not concurrent. Installation of the firmware will cause an unconditional
reboot of the system. Therefore, all user operations should be gracefully terminated before firmware
updates are applied.
