Updating Firmware From a Tape Cartridge

Updating Firmware on Sled-Mounted and Desktop DLT2000XT Tape

Drives

Follow these steps:

1. Make sure tape operations are ﬁnished. For the ﬁrmware update to be successful,

the drive must have passed the power-on self-test (POST).

2. Remove any cartridge in the DLT2000XT tape drive and close the load/unload

handle.

3. Press down and hold the Unload button for about six seconds until the Write Protect

LED blinks. This indicates that the drive subsystem has recognized your request for

ﬁrmware update mode and is waiting for the sequence to complete.

If the Write Protect LED does not blink, make sure that

• the drive passed the POST

• the drive is unloaded

• the drive handle is in the down position

4. Release the Unload button. Immediately (within four seconds) press it again, for less

than one second.

The Write Protect and Tape in Use LEDs blink, indicating that the drive subsystem

recognizes that ﬁrmware update mode has been selected.

If selecting the ﬁrmware update mode is not successful, the Write Protect LED stops

blinking within several seconds. Try the procedure again. If the drive and controller

are not communicating properly, you cannot select ﬁrmware update.

5. Once you have successfully selected ﬁrmware update mode, load the update

cartridge into the drive. The Write Protect and Tape in Use LEDs temporarily go

dark as the DLT2000XT tape drive reads the tape and examines the new ﬁrmware

data. Calibration and directory processing cause the tape to move for a few minutes

before data is actually read.

Caution: Never turn off power to the DLT2000XT tape drive while the ﬁrmware is

being updated. Doing so interrupts the update process, and can damage the unit.

The drive automatically veriﬁes that the data is a valid DLT2000XT ﬁrmware

upgrade. Firmware update mode is automatically cleared at this point.
