7.2 DLT4000 Firmware Update Overview
The DLT4000 Cartridge Tape Subsystem family can automatically update the
controller firmware directly from a tape containing the appropriate information.
The user places the subsystem into Firmware Update Mode via the front panel and
then simply load a tape that includes the DLT4000 firmware image file.
The subsystem automatically reads and verifies the tape information as a valid
DLT4000 firmware image. If the image data passes all the verifications, the image
data is installed into the controller's nonvolatile code memory.
This chapter details the firmware update procedure.
Before doing the procedure, remember:
_________________________ CAUTION _________________________
During the firmware update, when the new image is actually being
programmed into the FLASH EEPROMs, a powerfail (but not BUS
RESET) causes the controller module to be unusable. When doing a
firmware update, take reasonable precautions to prevent a powerfail.
