Maintenance
j.
If LED combination 7-0 is
being
displayed
(indicating
the
successful
completion
of
the
self test), run DSM for more
extensive troubleshooting.
(Refer
to
the
support-user/DSM
operations described in the HP 30010A/30020A/B Intelligent
Network Processor Diagnostic Procedures Manual.)
k.
If any other combination of lighted LEDs (not already covered
in steps f through j)
is being displayed as a result of your
having pressed the RESTART switch in step d, replace the
INP
PCA
board
(part
no.
30020-60009).
(See paragraph 4-18,
"Replacement of the PCA Board".)
NOTE
When sending PCA boards to
the
factory
for
replacement,
refer
to
paragraph
4-19,
"Reshipment
Instructions".
Include in the package your noted obser-
vations from step b;
they may be
help-
ful
during
factory-level
trouble-
shooting.
Also, if a
5-0
or
3-0
LED
pattern
was
observed in step b, an INP
dump
file
may
have
been
created
in
PUB.SYS
(labeled INPLOGnn , where nn is
in the range from 00 to
99).
If
they
can
be
located,
these
INPLOG
files
should also be included in
the
package
with
the
defective
equipment.
(See
Appendix B for
further
information
on
the INP dump files.)
4-15. Off-Board Loopback Testing
When support-user
diagnostic
testing
is
required
beyond
the
physical
limits
of
the
INP PCA board, certain portions of the
data communications network can be synthesized.
A test hood and/
or a test connector are needed for
testing
with
certain
cable
options
(see
table
1-2
for
test
equipment
compatibility
information).
These test attachments are used with the off-board
loopback tests described in the HP 30010A/30020A/B Intelligent
Network
Processor
Diagnostic
Procedures Manual.
The test hood
and test connector are illustrated in figure 1-1
and
listed
by
part
number
in
table
1-2.
Th~
test attachments are used as
follows:
