Chapter 4. Managing Firmware

• A RXT-150 is running a version of
firmware that changes how data is
written to the media.
• A RXT media pack is loaded that has
never been written to using this
firmware.
• The RXT-150 writes Auto Firmware to
the RXT media pack, and writes data to
the pack using the newest format.

Technology Note: How Auto Firmware Works
RXT-150 drives contain firmware, and RXT media packs store a copy of the drive firmware on the pack as
Auto Firmware. For the RXT-150 to read data from a RXT media pack, the drive firmware must be at or exceed
the media’s Auto Firmware level. If it isn’t, you are notified to upgrade the drive with the pack’s Auto
Firmware.
Drive has firmware that writes
data using a newer format; the
drive firmware is copied onto the
pack as Auto Firmware.
Pack now has data
that can only be read
by a drive with
firmware at or above
the pack’s Auto
Firmware version
This pack is put into a RXT-150 that can’t
read the pack’s data because the drive’s
firmware is not at or above the pack’s Auto
Firmware version. A message notifies the
user to update the RXT-150, optionally
using the pack’s Auto Firmware.
If the pack has User
Firmware at a
higher level
than the Auto
Firmware, the
user could
upgrade
using User
Firmware.
• A RXT-150 is running a version of
firmware that writes data in an older
format.
• A user inserts a RXT media pack with
data written using a newer firmware
version.
• The user is informed of the
discrepancy.
• The user can now update the RXT-150
using the RXT media Auto Firmware
Note: All RXT-150 drives with the most recent level of firmware can read data
written using earlier versions of RXT-150 firmware.
