Service Library: Upgrade Firmware
This page displays the current library and drive firmware versions. Firmware can
be downloaded to the host then uploaded to the drive in the library by using this
page.
In the first line you can see the actual loaded firmware revision or level installed
on the drive. Click Browse... to choose the firmware file you have downloaded
from the web site on the first drive you want to update (You can not update 2
drives at the same time). Be sure you choose the correct firmware for your drive
type. After pressing the Update button the file will be sent to the drive and the
drive will be upgraded.

Note: During the update no host drive action is possible. The drive update takes

approximately 5 minutes. The system status panel (in the right of the
browser window) will change from ″update″ to ″ready″.
