2. PRISMAsync Controller Firmware

CAUTION
The parameters of the USB flash drive, used as the USB stick and USB
Key, are very specific (see Table 79 – USB Flash Drive Specifications (for
the USB Key and USB Stick))). Using a USB flash drive that does not
meet these parameters may result in an error when backing up the
system or an error during firmware installation.
WARNING
The USB flash drives used to create a system backup and to install
firmware must not be used interchangeably. The preparation process to
install firmware requires that the USB flash drive be formatted. Any data
on the USB flash drive would be lost. This includes system backup data.
a) PRISMAsync Controller System Backup
A USB flash drive (USB key) is included with the PRISMAsync
controller. The USB Key is available to save a back up of the
PRISMAsync controller system and licenses.
It is highly recommended that a service technician create a system
backup to the USB key after device installation, a major system
change or a system upgrade.
A service technician can restore the PRISMAsync controller system
and licenses after an upgrade or system failure. The USB key must
be kept with the imagePRESS Device.
b) PRISMAsync Controller Firmware Updates
A USB flash drive (USB stick), is available for purchase, to upgrade
or restore the PRISMAsync controller firmware. The process to
prepare the USB stick, to make it ready to install firmware, formats
the USB stick (eliminating all contents) and downloads the new
firmware to the USB stick.
During the PRISMAsync Controller firmware update process, the
current firmware is erased and replaced by firmware installed from
the USB stick. Therefore, it is highly recommended that the service
technician/system engineer backup the system using a separate USP
Flash drive (the USB key), see System Backup. After the Firmware
update, the installed licenses can be restored using the USB key.
Once the USB stick has been used to update firmware on the
PRISMAsync controller, it cannot be used again to update firmware
until the preparation process has been repeated.
