Function Code 7: Run RS-422 Wrap Test
This test causes the drive to perform a check of the circuitry from and to the LDI
or RS-422 connector.
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.
2. Within a 1.5-second interval, press the Unload Button three times. The Status
Light becomes solid amber, which means that the drive is in maintenance
mode.
3.
Press the Unload Button once per 1.5 seconds 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 the test is successful, it loops and begins again. To half the test, press the
Unload Button. The test continues to the end of its loop and then stops. The
drive then displays
0
and exits maintenance mode.
v If the test fails,
9
displays, the test stops, and the drive exits maintenance
mode. To resolve the error, locate
9
in Table 15 on page 75
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 32.
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:
v If the operation is successful, the tape drive displays function code
0
,
rewinds and unloads the newly converted scratch data cartridge, and exits
maintenance mode.
v If the operation is not successful, an error code displays. To determine the
error, locate the code in Table 15 on page 75. To clear the error, turn the
power off, then on again.
