v If you are installing a SCSI removable-media drive, use the one-drop SCSI cable that comes with the drive and connect it to SCSI channel A (SCSI1). See "Power and signal cables for internal drives" on page 26 for additional information about cabling drives and "System-board internal connectors" on page 8 for the location of IDE and SCSI connectors on the system board. v If there are open connectors on the cable connecting an existing IDE drive, you can use this cable to connect the new drive. The 4-connector SCSI cable that comes with non-hot-swap model servers cannot be used to connect a SCSI drive in bay 2. 13. Route the signal cable so that it does not block the airflow to the rear of the drives or over the microprocessor and memory. 14. If you have another drive to install or remove, do so now. 15. If you have other options to install or remove, do so now; otherwise, replace the support bracket (see "Removing and installing the support bracket" on page 14), replace the bezel (see "Replacing the bezel" on page 39), and then go to "Completing the installation" on page 38. Installing a hot-swap SCSI hard disk drive in bay 4, 5, 6, 7, 8, or 9 Some server models support hot-swap hard disk drives. The SCSI ID for each hot-swap hard disk drive is printed on the hot-swap lock bar. Before you install a hot-swap hard disk drive, read the following information: v Inspect the drive tray for signs of damage. v Make sure that the drive is correctly installed in the tray. v To maintain proper system cooling, do not operate the server for more than 10 minutes without either a drive or a filler panel installed in each drive bay. v All hot-swap drives in the server must have the same speed rating; if you mix speed ratings, all drives will operate at the speed of the slowest drive. v You do not have to turn off the server to install hot-swap drives in the hot-swap drive bays. v Set the drive jumpers either to disable auto-start or to delay startup, to prevent overtaxing the system power supply by all drives trying to spin up at once. v Install hot-swap hard disk drives in this sequence: bay 9, bay 8, bay 7, bay 6, bay 5, and bay 4. v If your server has an optional RAID adapter, see the documentation that comes with the adapter for instructions for installing a hard disk drive. v Each hot-swap drive has two LEDs: the hard disk drive activity LED and the hard disk drive status LED. When the green hard disk drive activity LED is flashing, it indicates that the controller is accessing the hard disk drive. When the amber hard disk drive status LED is lit continuously, it indicates that the drive is faulty and must be replaced. When the amber hard disk drive status LED is flashing, it indicates that the drive is being rebuilt. The server hot-swap bays are connected to a SCSI backplane. This backplane is the printed circuit board behind the bay. The backplane controls the SCSI IDs for the hot-swap drives. The following illustration shows how to install a hot-swap hard disk drive.

v
If
you
are
installing
a
SCSI
removable-media
drive,
use
the
one-drop
SCSI
cable
that
comes
with
the
drive
and
connect
it
to
SCSI
channel
A
(SCSI1).
See
“Power
and
signal
cables
for
internal
drives”
on
page
26
for
additional
information
about
cabling
drives
and
“System-board
internal
connectors”
on
page
8
for
the
location
of
IDE
and
SCSI
connectors
on
the
system
board.
v
If
there
are
open
connectors
on
the
cable
connecting
an
existing
IDE
drive,
you
can
use
this
cable
to
connect
the
new
drive.
The
4-connector
SCSI
cable
that
comes
with
non-hot-swap
model
servers
cannot
be
used
to
connect
a
SCSI
drive
in
bay
2.

Route
the
signal
cable
so
that
it
does
not
block
the
airflow
to
the
rear
of
the
drives
or
over
the
microprocessor
and
memory.

If
you
have
another
drive

remove,
do
so
now.

have
other
options
to

remove,
do
so
now;
otherwise,
replace
the
support
bracket
(see
“Removing
and
installing
the
support
bracket”
on
page
14),
replace
the
bezel
(see

Installing
a
hot-swap
SCSI
hard
disk
drive
in
bay
4,
5,
6,
7,
8,
or
9
Some
server
models
support
hot-swap
hard
disk
drives.
The
SCSI
ID
for
each
hot-swap
hard
disk
drive
is
printed
on
the
hot-swap
lock
bar.
Before
you
install
a
hot-swap
hard
disk
drive,
read
the
following
information:
v
Inspect
the
drive
tray
for
signs
of
damage.
v
Make
sure
that
the
drive
is
correctly
installed
in
the
tray.
v
To
maintain
proper
system
cooling,
do
not
operate
the
server
for
more
than
10
minutes
without
either
a
drive
or
a
filler
panel
installed
in
each
drive
bay.
v
All
hot-swap
drives
in
the
server
must
have
the
same
speed
rating;
if
you
mix
speed
ratings,
all
drives
will
operate
at
the
speed
of
the
slowest
drive.
v
You
do
not
have
to
turn
off
the
server
to
install
hot-swap
drives
in
the
hot-swap
drive
bays.
v
Set
the
drive
jumpers
either
to
disable
auto-start
or
to
delay
startup,
to
prevent
overtaxing
the
system
power
supply
by
all
drives
trying
to
spin
up
at
once.
v
Install
hot-swap
hard
disk
drives
in
this
sequence:
bay
9,
bay
8,
bay
7,
bay
6,
bay
5,
and
bay
4.
v
If
your
server
has
an
optional
RAID
adapter,
see
the
documentation
that
comes
with
the
adapter
for
instructions
for
installing
a
hard
disk
drive.
v
Each
hot-swap
drive
has
two
LEDs:
the
hard
disk
drive
activity
LED
and
the
hard
disk
drive
status
LED.
When
the
green
hard
disk
drive
activity
LED
is
flashing,
it
indicates
that
the
controller
is
accessing
the
hard
disk
drive.
When
the
amber
hard
disk
drive
status
LED
is
lit
continuously,
it
indicates
that
the
drive
is
faulty
and
must
be
replaced.
When
the
amber
hard
disk
drive
status
LED
is
flashing,
it
indicates
that
the
drive
is
being
rebuilt.
The
server
hot-swap
bays
are
connected
to
a
SCSI
backplane.
This
backplane
is
the
printed
circuit
board
behind
the
bay.
The
backplane
controls
the
SCSI
IDs
for
the
hot-swap
drives.
The
following
illustration
shows
how
to
install
a
hot-swap
hard
disk
drive.
