VECTOR 4
TECHNICAL INFORMATION
PART V - TROUBLESHOOTING GUIDE
The following section outlines troubleshooting procedures for
hardware-related failures of the Vector 4 single-board computer,
The troubleshooting procedures are divided into two parts: a
flowcharted procedure in which the system is run in a controlled
environment until the symptom is duplicated; and a series of
symptom-check tables, where the symptoms identified in the first
procedure are referenced to their possible causes. The location of
each checkpoint on the single-board computer can be found in
Exhibit VI-12, a fold-out located at the rear of the book. When
using the symptom-check, wave form, or test point tables, you can
open Exhibit VI-12 for easy reference from any page.
CAUTION
The console cover is an integral part of the cooling system of the Vector 4.
If the cover will be removed for service for a period of one hour or longer,
remove hard disk drive to allow proper air circulation.
