Repair Philosophy
Field Repair Philosophy for the Series 300 Computers and the HP 98568 Bus Expander is
assembly level. This Ineans that when a failure occurs, the problem is diagnosed to the assembly
having the failed part. That assembly is then replaced. Replacement assemblies are available
through local HP Sales and Service Offices.
SOIne assemblies may be replaced with rebuilt ones instead of new ones. Other assemblies are
only available as new ones. Refer to the Series 300 Service Handbook, Chapter 8, Replaceable
Parts, for infornlation on replacement parts.
Schematics
In support of the repair philosophy, this manual contains information to the assembly level.
Schematics are not available for these products.
Supported Configurations
Only Series 300 Conlputer Systems with Hewlett-Packard approved parts, accessories, peripher-
als, operating systems and application programs are supported by Hewlett-Packard. Any Series
300 Computer System with other than HP approved hardware or software connected or installed
must have the non-HP approved hardware and software removed by the customer before On-Site
or Service Center repair is accomplished.
Hewlett Packard Support
Hewlett-Packard provides service support in three ways:
• On-Site Repair.
• Service Center Repair.
• Customer Repair.
Each of these are explained in the sections below.
On-Site Repair
For On-Site Repair, an HP Customer Engineer goes to the customers site, troubleshoots, and
repairs the hardware to the assembly level. The defective assembly is replaced with a new or
rebuilt assembly. This service is available through a service contract or a time-and-materials
basis.
Hewlett-Packard Service Center Repair
The customer returns the defective product to the nearest HP Repair Center. An HP Customer
Engineer repairs the product to the assembly level in the same manner as On-Site Repair. Upon
being repaired, the product is returned to the customer. Contact your nearest HP Sales and
Service Office for the location of the HP Repair Center, typical turn-around times, and shipping
instructions.
