Abstract

This article describes a technique which allows a user to isolate a problem in a processing system between the file adapter and the file unit efficiently and without adding any wrap cable or using external tools. In a processing system where there is a floppy file or a hard file, the problem of isolating an error to a field replacable unit (FRU) level may be tedious and costly. This comes from the fact that the file assembly consists of a file adapter, cable(s) and file(s) as shown in Fig. 1. If there is a problem in the adapter, the cable or the file, it can be manifested to the CPU as error in reading a file or writing a file.
