An Overview of the Maintenance Tasks
The tasks in this document are divided into three categories. One is Routine
Maintenance, which documents the simple routine maintenance tasks
required by the system. Routine maintenance is always the responsibility of
the customer, regardless of whether the customer has purchased a
maintenance contract. These tasks consist of periodically cleaning the fan
filters at the bottom of the cabinets and cleaning the heads of the tape units.
The second category includes the Troubleshooting and Fault Clearing
procedures. These procedures are used to identify the source of faults and
potential solutions. The Maintenance Service of System Administrative
Services supports these procedures.
The Maintenance Service is a software program provided with the system's
base software that isolates and diagnoses faulty equipment and software.
Faulty units are automatically taken out of service by the system. The system
also provides for manually taking units out of service.
The third category is Replacing Cabinet Subassemblies. Because of the
system's modular design, most equipment can be quickly removed and
replaced by spare units. (The customer should have a spare for each type of
equipment on the site.) Except for the specific cabinet subassemblies
documented here, the equipment should be removed and replaced according to
the detailed procedures in the Installation Guide for Cabinet Systems,
450-1011-201.
