Troubleshooting Topics
General troubleshooting tips
When

does
not
perform
as
expected,
look
for
symptoms
that
might
point
to
the
cause.
Performing
the
following
actions
can
help
diagnose
the
problem:
•
Check
the
state
of
the
LEDs
on
the
CPM
and
other
modules
in
the
platform,
especially
the
power
and
out
of
service
LEDs.
•
Check
temperatures
on
the
CPM.
If
the
Radisys
Shelf
Manager
is
used,
see
the
troubleshooting
information
in
the
Shelf
Management
Software
Reference
for
details
on
how
to
perform
these
queries.
•
Verify
the
IP
address
and
the
subnet
mask
assignment.
See
the
Software
Guide
for
Management
Processors
and
General
Purpose
Computing
Processors
