Note: This function is described here for information only. It is not supported on
the TS2250 Tape Drive.
This test causes the drive to perform a check of the circuitry and connector for the
RS-422 interface. This connector supports the Library Drive Interface (LDI) and the
Automation Drive Interface (ADI).
Before selecting this function, attach an LDI or RS-422 wrap plug to the drive's LDI
or RS-422 connector (in place of the LDI or RS-422 cable).
1. Make sure that no cartridge is in the drive, and the appropriate wrap plug is
attached to the RS-422 connector.
2.
Place the drive in Maintenance Mode. For instructions, see “Entering
Maintenance Mode” on page 3-9.
3. Press the Unload Button once per second until
7
appears in the
Single-character Display (SCD). If you cycle past
7
, continue to press the
Unload Button until it displays again.
4. To select the function, press and hold the Unload Button for three seconds.
After you select the function,
7
flashes and the drive automatically starts the
test.
v If no error is detected, the diagnostic test loops and begins again. To stop
the loop, press
Unload
for 1 second and release. When the diagnostic test
ends,
0
temporarily appears in the SCD, and the tape drive exits
Maintenance Mode.
v If an error is detected, the Fault light flashes and the drive posts an error
code to the SCD. To determine the error, locate the code in Appendix A,
“Error Codes and Messages,” on page A-1. To clear the error either turn the
power off and then on again, or reboot the drive by pressing and holding
Unload for 10 seconds.
Function Code 8: Unmake FMR Tape
Function Code
8
erases the field microcode replacement (FMR) data and
rewrites the cartridge memory on the tape. This converts the cartridge into a valid
scratch (blank) data cartridge.
1. Place the drive in maintenance mode. For instructions, see “Entering
Maintenance Mode” on page 3-9.
2. Press the Unload Button once per second until
8
appears in the SCD. (If you
cycle past the desired code, press the Unload Button once per second until the
code reappears.)
3. Press and hold the Unload Button for three or more seconds, then release it to
select function
8
. The SCD changes to a flashing
C
.
4. Insert the FMR data cartridge (or the tape drive exits maintenance mode). The
SCD changes to a flashing
8
. The tape drive erases the firmware on the tape
and rewrites the header in the cartridge memory to change the cartridge to a
valid scratch (blank) data cartridge. The drive then ejects the cartridge and exits
Maintenance Mode.
