Preface
P
This Service Maintenance Manual is a troubleshooting guide that can be used for
reference when servicing DIGITAL Servers.
DIGITAL reserves the right to make changes to this Service Maintenance Manual
without notice. Accordingly, the illustrations and procedures in this document might
not apply to all DIGITAL Servers to be serviced since many of the diagnostic tests
are designed to test more than one product.
CAUTION:
DIGITAL recommends that only A+/DIGITAL
Server certified engineers attempt to repair this equipment.
All troubleshooting and repair procedures are detailed to
support subassembly/module level exchange. Because of the
complexity of the individual boards and subassemblies, no
one should attempt to make repairs at the component level or
make modifications to any printed circuit board. Improper
repairs can create a safety hazard. Any indications of
component replacement or circuit board modifications might
void any warranty or exchange allowances.
