Figure 2-4 AX23 Self-Test Code (STRG-1)
The codes for DUA3. DUAl, and DUAO should be 7s. The code for the
STRG-1 controller should be .0001. The code for DUA2 should be a 1. If
any other code (except 7 (off-line) or F (controller failure)) appears for DUA2,
check lhe drive for power, make sure the test diskette is loaded properly, and
check the cables for a good collllection. If the code is still not a 1, the
problem is either in the drive. on the MSC module, in the cables. or on the
system module. Refer to Table 2-5 to determine the cause of the problem. A
complete listing of the self-test codes are listed in Appendix E.
