Troubleshooting checklist

Much of the troubleshooting required for the EIU is handled at the frame,
shelf, and software load levels. There are, however, some problems that
operating company personnel can troubleshoot at the EIU level.
Table 30 lists the problems that the operating company and customers can
encounter. The table also lists probable causes, referenced to the list at the end
of the table.
