This Service Maintenance Manual is a troubleshooting guide that can be used
for reference when servicing Prioris XL 6000 Series 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 Prioris XL 6000 Series servers to be serviced since many
of the diagnostic tests are designed to test more than one product.
CAUTION:
Digital recommends that only A+ 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 atttempt 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.
