5.
Label
each
cable
that
connects
to
the
RAID
controller
that

the
battery.
6.
Use
the
storage
management
software
to
take

before
you
can
replace
the
RAID
controller
battery.
For
the
proper
shutdown
sequence,

CRU
bottom
up
on
a
flat
surface.
Using
a
#2
Phillips
head
screwdriver,
remove
the
six
screws
(three
on
each
side
of
the
RAID
controller)
that
hold
the
RAID
controller
bottom
panel
to
the
sides
of
the
RAID
controller,
as
shown
in
10.
Slide
the
RAID
controller
bottom
panel
away
from
the
front
side
of
the
RAID
controller
(away
from
the
SFP
slots
and
black
center
latch)
to
unlatch
it
from
the
side
panels.
11.
Carefully
flip

that
holds
the
battery
access
panel.
Carefully
slide
the
access
panel
toward
the
front
to
unlatch
it
from
the
three
pins
mounted
on
the
RAID
controller
bottom
panel.
13.
Remove
the
battery
unit
and
place
it
on
a
dry,
level
surface.
If
this
battery
is
a
replacement
battery,
then
replace
the
old
battery
with
the
new
one.
14.
Write
the
battery
replacement
information
on
the
label
on
the
battery
pack.
