5-1. INTRODUCTION

This chapter provides service and repair assistance instructions, service diagrams, a complete electronic parts list for the printed circuit board assembly and a reference to the controller's self diagnostic.

5-2.

SERVICE DIAGRAMS

The controller board jumper and component loca-tions, and schematic diagrams (Figure 5-1 through 5-3) are included at the end of this chapter. Note that these diagrams are intended only for reference; they reflect the iSBC 215 controller design at the time this manual was printed. The schematics and component location diagrams packaged with the controller reflect the design version shipped and thus super-cede the diagrams in this manual.

5-3.

SERVICE AND REPAIR ASSISTANCE United States customers can obtain service and repair assistance from Intel by contacting the Intel Product Service Hotline in Phoenix. Arizona.

Customers outside the United States should contact their sales source (Intel Sales Office or Authorized Distributor) for service information and repair assistance.

Before calling the Product Service Hotline, you should have the following information available:

a. Date you received the product.

b. Complete part number of the product (including dash number). On boards, this number is usually silk-screened onto the board. On other MCSD products, it is usually stamped on a label.

c. Serial number of product. On boards, this num-ber is usually stamped on the board. On other MCSD products, the serial number is usually stamped on a label.

d. Shipping and billing addresses.

e. If your Intel Product warranty has expired, you must provide a purchase order number for billing purposes.

f. If you have an extended warranty agreement, be sure to advise the Hotline personnel of this agreement.

CHAPTER 5 SERVICE INFORMATION

Use the following numbers for contacting the Intel Product Service Hotline:

Telephone:

All U.S. locations,

Except Alaska, Arizona, & Hawaii (800) 528-0595

All other locations: (602) 869-4600 TWX Number:

910 -951 - 1330

Always contact the Product Service Hotline before returning a product to Intel for repair. You will be given a repair authorization number, shipping instructions, and other important information which will help Intel provide you with fast, efficient service. If you are returning the product because of damage sustained during shipment or if the product is out of warranty, a purchase order is required before Intel can initiate the repair.

5-4.

SELF DIAGNOSTIC

A self diagnostic is provided with the iSBC 215 controller, stored in the on-board PROM. It performs a go/no-go test of the controller hardware and firmware. If the controller passes the test, it indicates with a high degree of certainty that the controller is operating properly. See the discussion of the diagnostic in Chapter 3 for a description of the program and instructions for initiating the operation.

5-5. REPLACEABLE COMPONENTS

This section contains the information necessary to procure replacement components directly from commercial sources. Component manufacturers have been abbreviated in the parts list with a two to five character code. Table 5-1 cross-references the manufacturer's code with the name and location of the prime commercial source. Table 5-2 lists all the replaceable components on the controller board.

Note that the components that are available com-mercially are listed in the "MFR CODE" column as

"COML" and that they are ordered by description (OBD). Procure commercially-available components from a local distributor whenever possible.
