Appendix C. Error Recovery Procedures - IBM 7208 Service Manual

C.0 Appendix C. Error Recovery Procedures
Use Figure 30 to resolve error messages that appear on the LCD of the 7208 Tape Drive Model 342:
1. Determine the fault symptom code (FSC) in the error message (the first two digits in the message). For example, in error message
ERR 1: AD 58 C0, the FSC is AD.
2. Locate the FSC in Figure 29 in topic B.0 and identify the error recovery procedure (ERP) number for that FSC.
3. Locate the ERP number in Figure 30, and identify the recommended error recovery procedure. If two or more ERP codes are listed for
the fault symptom code in Figure 29 in topic B.0, perform the action for the first code, then perform the action for the second code, and
so on.
