Powering
the
System
On
and
Off
Power
for
the
I/O
subsystems
is
controlled
by
the
attached
processor
subsystem
and
the
System
Power
Control
Network
(SPCN).
For
information
about
procedures
to
power
the
system
on
and
off,
refer
to
the
service
guide
of
the
processor
subsystem
to
which
the
I/O
subsystem
is
attached.
Power-On
Self-Test
After
power
is
turned
on
and
before
the
operating
system
is
loaded,
the
system
does
a
power-on
self-test
(POST).
The
RIO
loop
that
connects
the
I/O
subsystems
to
the
system
unit
is
tested.
Tests
are
also
performed
on
the
installed
adapters
and
devices
in
the
I/O
subsystems.
If
an
error
occurs
during
the
POST,
an
error
code
is
displayed
on
the
system
operator
panel
LCD
that
indicates
which
part
is
failing
and
which
subsystem
contains
the
error.
