Some
models
have
an
optional
hard
disk
drive
mounting
bracket
1
installed.
When
this
bracket
is
installed,
access
to
some
of
the
CRUs
or
FRUs
inside
the
chassis
is
restricted.
Note:
There
appears
to
be
two
drive
bays
in
the
bracket.
However,
due
to
thermal
restrictions,
only
the
bay
2
at
the
rear
of
the
chassis
can
be
used
to
install
a
hard
disk
drive.
See
“Pivoting
or
removing
the
optional
hard
disk
drive
mounting
bracket”
on
page

To
replace
the
computer
cover,
