Table 5. Diagnostic and maintenance functions (continued)
Function Code 7 - Run LDI or RS-422 Wrap Test
Causes the tape drive to perform a check of the circuitry from and to the LDI or RS-422 connector.
Before you select this function, attach an LDI or RS-422 wrap plug to the tape 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. If you cycle past 7,
continue to press the unload button until it redisplays.
4. To select the function, press and hold the unload button for 3 seconds. After you select the function, 7 flashes
and the tape drive automatically starts the test:
v If the test is successful, it loops and begins again. To halt the test, press the unload button. The test continues
to the end of its loop and then stops. The tape drive then displays 0 and exits maintenance mode.
v If the test fails, 9 displays, the test stops, and the tape drive exits maintenance mode. To resolve the error,
locate 9 in Table 8 on page 49.
