4.1
Upgrading Firmware From Tape
The 5242 tape drive allows you to upgrade firmware by inserting a firmware upgrade cartridge. The
process takes approximately 3 minutes to complete.
Caution: Do not disconnect power at any time during the upgrade process, particularly when the
front panel lights are flashing, or it may result in the drive having corrupt firmware or no
firmware at all. The drive will then have to be returned to the factory.
1. If the firmware upgrade is incompatible with your hardware, no upgrade takes
place. The tape is ejected after 1 minute instead of the usual 3 minutes.
2. The upgrade tape must not be write-protected.
3. The upgrade tape can only be used a certain number of times. After that, a tape
drive reformats it for normal data use. However, it is not advisable to use it for
data.
4. You cannot convert a firmware upgrade tape for normal use.
4.1.1 Upgrading the Firmware
4.1.1.1 Check that the tape drive is not engaged in any SCSI activity. The tape LED is off and the
NonStop server is not going to be accessing the drive.
4.1.1.2 Insert the firmware upgrade tape cartridge into the drive.
4.1.1.3 The upgrade process automatically takes place. During the actual erasure and reprogramming of
the firmware, it is critically important that you do not power down the tape drive. The front panel
LEDs flash rapidly during this critical time.
4.1.1.4 After about 3 minutes, when the upgrade is complete, the firmware cartridge ejects. Remove it, and
replace it in its box.
