Attention:
These
notices
indicate
possible
damage
to
programs,
devices,
or
data.
An
attention
notice
appears
before
the
instruction
or
the
situation
in
which
damage
might
occur.
Note:
These
notices
provide
important
tips,
guidance,
or
advice.
Use
the
reference
numbers
in
parentheses,
for
example
(1),
at
the
end
of
each
notice
to
find
the
matching
translated
notice.
For
all
danger,
caution,
and
attention
notices,
see
the
IBM
System
Safety
Notices

Inspecting
the
SAN
Volume
Controller
for
unsafe
conditions
Use
caution
when
working
in
any
potential
safety
hazardous
situation
that
is
not
covered
in
the
safety
checks.
If
unsafe
conditions
are
present,
determine
how
serious
the
hazards
are
and
whether
you
can
continue
before
you
correct
the
problem.
Before
you
start
the
safety
inspection,
make
sure
the
power
is
off,
and
the
power
cord
is
disconnected.
Each
machine
has
required
safety
items
installed
to
protect
users
and
service
personnel
from
injury.
This
guide
addresses
only
those
items.
Important:
Good
judgment
must
also
be
used
to
identify
potential
safety
hazards
due
to
attachment
of
non-IBM
features
or
options
not
covered
by
this
inspection
guide.
If
any
unsafe
conditions
are
present,
you
must
determine
how
serious
the
apparent
hazard
could
be
and
whether
you
can
continue
without
first
correcting
the
problem.
For
example,
consider
the
following
conditions
and
their
potential
safety
hazards:
Electrical
hazards
(especially
primary
power)
Primary
voltage
on
the
frame
can
cause
serious
or
lethal
electrical
shock.
Explosive
hazards
A
damaged
CRT
face
or
a
bulging
capacitor
can
cause
serious
injury.
Mechanical
hazards
Loose
or
missing
items
(for
example,
nuts
and
screws)
can
cause
serious
injury.
Perform
the
following
steps
to
inspect
each
SAN
Volume
Controller
node
for
unsafe
conditions.
If
necessary,
see
any
suitable
safety
publications.
1.
Turn
off
the
SAN
Volume
Controller
and
disconnect
the
power
cord.
2.
Check
the
frame
for
damage
(loose,
broken,
or
sharp
edges).
3.
Check
the
power
cables
using
the
following
steps:
a.
Ensure
that
the
third-wire
ground
connector
is
in
good
condition.
Use
a
meter
to
check
that
the
third-wire
ground
continuity
is
0.1
ohm
or
less
between
the
external
ground
pin
and
the
frame
ground.
b.
Ensure
that
the
power
cord
is
the
appropriate
type,
as
specified
in
the
parts
listings.
c.
Ensure
that
the
insulation
is
not
worn
or
damaged.
4.
Check
for
any
obvious
nonstandard
changes,
both
inside
and
outside
the
machine.
Use
good
judgment
about
the
safety
of
any
such
changes.
