Unload Button Function How to Initiate the Function
Rewind the tape into the
cartridge and eject the
cartridge from the drive
Press the Unload Button once. The Status Light flashes green while the drive is
rewinding and unloading.
Note: During a rewind and eject operation, the drive does not accept SCSI commands
from the server.
Place the drive in
maintenance mode
Ensure that the drive is unloaded. Then, within two seconds, press the Unload Button
three times. The drive is in maintenance mode when the Status Light becomes solid
amber and
0
appears in the SCD.
Note: While in maintenance mode, the drive does not accept SCSI interface
commands.
Scroll through the
maintenance functions
While in maintenance mode, press the Unload Button once per second to increment
the display characters by one. When you reach the character of the diagnostic or
maintenance function that you want (see “Diagnostic and Maintenance Functions” on
page 15), press and hold the Unload Button for three seconds.

0
displays. Then press and hold the Unload Button for three seconds. Maintenance
mode is exited when the Status Light becomes solid green and the SCD becomes
blank.
Force a drive dump (part of
the maintenance mode)
Attention: If the drive detects a permanent error and displays an error code, it
automatically forces a drive dump (also known as a save of the firmware trace). If
you force a drive dump, the existing dump will be overwritten and data will be lost.
After you force a drive dump, do not turn off the power to the drive or you may lose
the dump data.
Choose one of the following procedures:
v
If the drive is in maintenance mode (Status Light is solid amber), refer to “Function
Code 4: Force a Drive Dump” on page 18.
v
If the drive is in operating mode (Status Light is solid or flashing green), press and
hold the Unload Button for ten seconds.
If captured dump data exists, the drive places it into a dump area.
Reset the drive Press and hold the Unload Button on the drive for ten seconds. The drive saves a
dump of the current drive state, then reboots to allow communication. Do not cycle
power as this will erase the contents of the dump.
Inserting a Tape Cartridge
To insert a tape cartridge:
1. Ensure that the drive is powered-on.
2. Ensure that the write-protect switch is properly set (see “Write-Protect Switch”
on page 34).
3. Grasp the cartridge so that the write-protect switch faces you (

in Figure 7
on page 14).
4. Slide the cartridge into the tape load compartment.
Notes:
a.
If the cartridge is already in an ejected position and you want to reinsert it,
remove the cartridge then insert it again.
