Function code 7: Run RS-422 wrap test

Note: This function is described here for information only. It is not supported on the IBM TS2260,
TS2270, or the TS2280 tape drive.
This test causes the drive to process 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 this function is selected, 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 23.
3. Press Unload once per second until
7
past , continue to press Unload until the code is displayed again.
4. To select the function, press and hold Unload for 3 seconds. After you select the function,
and the drive automatically starts the test.
v If no error is detected, the diagnostic test loops and begin again. To stop the loop, press Unload for
1 second and release. When the loop ends,
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 Table 17 on page 65. 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

8
Function code erases the field microcode replacement (FMR) data and rewrites the cartridge memory
on the tape. This action 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 23.
2. Press Unload once per second until
Unload once per second until the code reappears.)
3. Press and hold Unload for three or more seconds, then release it to select function
changes to a flashing
4. Insert the FMR data cartridge (or the tape drive exits Maintenance mode). The SCD changes to a
8
flashing . 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.
Note: If you inserted an invalid tape cartridge, error code
inserted a write-protected cartridge, or the media has read-only compatibility, error code
in the SCD. In either case, the tape drive unloads the cartridge and exits Maintenance mode after the
cartridge is removed.
v If the tape drive creates the scratch tape successfully, it rewinds and unloads the new tape, exits
Maintenance mode, and the tape is ready to use.
