NOTE:
With several products, after the firmware file is selected, a message is displayed to inform
the certain requirements such as important prerequisites for updating with the new firmware, or
noteworthy functional changes (such as a new LED sequence). Be sure to read any such messages
and take appropriate actions. If the device is either not visible to L&TT and operating system or
both after the firmware is updated successfully, follow the process indicated in the Firmware Update
window to ensure the updated device is fully visible and usable by the system. Make sure you
follow this entire procedure before calling HP customer support. In case the device is still not
accessible, call HP customer support for assistance.

revisions, select the check box to downgrade to the older firmware revisions.
•
