The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive bays. However, when you attach an external SCSI device to an optional SCSI adapter, you must set a unique ID for the device. See the information that comes with the device for instructions to set its SCSI ID. You can attach external SCSI devices using an optional SCSI adapter. To select and order the correct adapter for use with external devices, contact your IBM marketing representative or authorized reseller. When using an optional SCSI adapter, you must also connect the SCSI adapter to the SCSI LED connector on the system board to receive an indication of SCSI hard disk drive activity. Note: On server models that support SATA hard disk drives, you can attach only an external SCSI tape drive to an optional SCSI adapter. See "System board internal connectors" on page 86 for the location of the SCSI connectors. For information about the maximum length of SCSI cable, see the American National Standards Institute (ANSI) SCSI standards on the ANSI Web site at http://www.ansi.org/. Adhering to these standards will help to ensure that the server operates correctly. Universal Serial Bus connectors Use a Universal Serial Bus (USB) 2.0 connector to connect a USB device. USB 2.0 technology transfers data at up to 480 Mb per second (Mbps) with a maximum of 127 devices and a maximum signal distance of 5 meters (16 ft) per segment (if the device that is attached to the server is a USB 2.0 device). If multiple USB devices are attached to the server, the USB hub must be 2.0; otherwise, all USB 2.0 devices will transfer data at 12 Mbps. Using Plug and Play technology, USB devices are configured automatically. The following illustration shows a USB connector. 1 4 Use a 4-pin cable to connect a device to a USB connector. If you need to connect more USB devices than the server has USB connectors for, use a USB hub to connect additional devices. If you connect a PS/2 (non-USB) keyboard to the keyboard connector, USB ports and devices are disabled during POST. If you connect a USB keyboard that has a mouse port, the keyboard emulates a mouse, and you cannot disable the mouse settings in the Configuration/Setup Utility program. Video connector Use the video connector to connect a monitor to the server. The connector is dark blue to help you identify it. The following illustration shows an industry-standard 15-pin analog video connector on the rear of the server. 5 1 15 11 66 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

The
hot-swap-drive
backplane
controls
the
SCSI
IDs
for
the
internal
hot-swap
drive
bays.
However,
when
you
attach
an
external
SCSI
device
to
an
optional
SCSI
adapter,
you
must
set
a
unique
ID
for
the
device.
See
the
information
that
comes
with
the
device
for
instructions
to
set
its
SCSI
ID.
You
can
attach
external
SCSI
devices
using
an
optional
SCSI
adapter.
To
select
and
order
the
correct
adapter
for
use
with
external
devices,
contact
your
IBM
marketing
representative
or
authorized
reseller.
When
using
an
optional
SCSI
adapter,
you
must
also
connect
the
SCSI
adapter
to
the
SCSI
LED
connector
on
the
system
board
to
receive
an
indication
of
SCSI
hard
disk
drive
activity.
Note:
On
server
models
that
support
SATA
hard
disk
drives,
you
can
attach
only
an
external
SCSI
tape
drive
to
an
optional
SCSI
adapter.
See
“System
board
internal
connectors”
on
page
86
for
the
location
of
the
SCSI
connectors.
For
information
about
the
maximum
length
of
SCSI
cable,
see
the
American
National
Standards
Institute
(ANSI)
SCSI
standards
on
the
ANSI
Web
site
at
Adhering
to
these
standards
will
help
to
ensure
that
the
server
operates
correctly.
Universal
Serial
Bus
connectors
Use
a
Universal
Serial
Bus
(USB)
2.0
connector
to
connect
a
USB
device.
USB
2.0
technology
transfers
data
at
up
to
480
Mb
per
second
(Mbps)
with
a
maximum
of
127
devices
and
a
maximum
signal
distance
of
5
meters
(16
ft)
per
segment
(if
the
device
that
is
attached
to
the
server
is
a
USB
2.0
device).
If
multiple
USB
devices
are
attached
to
the
server,
the
USB
hub
must
be
2.0;
otherwise,
all
USB
2.0
devices
will
transfer
data
at
12
Mbps.
Using
Plug
and
Play
technology,
USB
devices
are
configured
automatically.
The
following
illustration
shows
a
USB
connector.
1
4
Use
a
4-pin
cable
to
connect
a
device
to
a
USB
connector.
If
you
need
to
connect
more
USB
devices
than
the
server
has
USB
connectors
for,
use
a
USB
hub
to
connect
additional
devices.
If
you
connect
a
PS/2
(non-USB)
keyboard
to
the
keyboard
connector,
USB
ports
and
devices
are
disabled
during
POST.
If
you
connect
a
USB
keyboard
that
has
a
mouse
port,
the
keyboard
emulates
a
mouse,
and
you
cannot
disable
the
mouse
settings
in
the
Configuration/Setup
Utility
program.
Video
connector
Use
the
video
connector
to
connect
a
monitor
to
the
server.
The
connector
is
dark
blue
to
help
you
identify
it.
The
following
illustration
shows
an
industry-standard
15-pin
analog
video
connector
on
the
rear
of
the
server.
