Completing
the
FRU
replacement
After
replacing
FRUs,
you
need
to
install
any
removed
parts,
replace
the
cover,
and
reconnect
any
cables,
including
telephone
lines
and
power
cords.
Also,
depending
on
the
FRU
that
is
replaced,
you
might
need
to
confirm
the
updated
information
in
the
Setup
Utility
program.
Note:
When
the
power
cord
is
first
plugged
in,
the
computer
might
appear
to
turn
on
for
a
few
seconds
and
then
turn
off.
This
is
a
normal
sequence
to
enable
the
computer
to
initialize.
1.
Ensure
that
all
components
have
been
reassembled
correctly
and
that
no
tools
or
loose
screws
are
left
inside
your
computer.
2.
Reposition
any
cables
that
might
impede
the
replacement
of
the
computer
cover.
Important
Correctly
route
all
power
supply
cables
to
avoid
interference
with
the
drive
bay
assembly.
Keep
cables
clear
of
the
hinges
and
sides
of
the
computer
chassis.
3.
Position
the
computer
cover
on
the
chassis
so
that
the
rail
guides
on
the
sides
of
the
cover
engage
the
rails
and
push
the
cover
to
the
closed
position
until
it
snaps
into
position.
4.
If
the
cover
is
secured
with
thumbscrews,
install
them.
5.
Reconnect
the
external
cables
and
power
cords
to
the
computer.
See
“Rear
connectors”
on
page
84.
6.
If
you
have
replaced
the
system
board,
you
must
update
(flash)
the
BIOS.
See
“Flash
update
procedures”
on
page
211.
7.
Some
FRU
replacements
require
the
configuration
to
be
updated.
See
Chapter
6,
“Using
the
Setup
Utility,”
