USB is an emerging serial interface standard for telephony and multimedia devices. It uses Plug and Play technology to determine the type of device attached to the connector. Notes: 1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB ports and devices will be disabled during the power-on self-test (POST). 2. If you install a USB keyboard that has a mouse port, the USB keyboard emulates a mouse and you will not be able to disable the mouse settings in the Configuration/Setup Utility program. USB cables and hubs You need a 4-pin cable to connect devices to USB 1 or USB 2. If you plan to attach more than two USB devices, you must use a hub to connect the devices. The hub provides multiple connectors for attaching additional external USB devices. USB technology provides 12 megabits-per-second (Mbps) speed with a maximum of 127 external devices and a maximum signal distance of five meters (16 ft.) per segment. USB-port connectors Each USB port has an external connector on the rear of the server for attaching USB compatible devices.

Universal
Serial
Bus
ports
Your
server
has
two
Universal
Serial
Bus
(USB)
ports,
which
configure
automatically.
USB
is
an
emerging
serial
interface
standard
for
telephony
and
multimedia
devices.
It
uses
Plug
and
Play
technology
to
determine
the
type
of
device
attached
to
the
connector.
Notes:
1.
If
you
attach
a
standard
(non-USB)
keyboard
to
the
keyboard
connector,
the
USB
ports
and
devices
will
be
disabled
during
the
power-on
self-test
(POST).
2.
If
you
install
a
USB
keyboard
that
has
a
mouse
port,
the
USB
keyboard
emulates
a
mouse
and
you
will
not
be
able
to
disable
the
mouse
settings
in
the
Configuration/Setup
Utility
program.
USB
cables
and
hubs
You
need
a
4-pin
cable
to
connect
devices
to
USB
1
or
USB
2.
If
you
plan
to
attach
more
than
two
USB
devices,
you
must
use
a
hub
to
connect
the
devices.
The
hub
provides
multiple
connectors
for
attaching
additional
external
USB
devices.
USB
technology
provides
12
megabits-per-second
(Mbps)
speed
with
a
maximum
of
127
external
devices
and
a
maximum
signal
distance
of
five
meters
(16
ft.)
per
segment.
USB-port
connectors
Each
USB
port
has
an
external
connector
on
the
rear
of
the
server
for
attaching
USB
compatible
devices.
The
following
table
shows
the
pin-number
assignments
for
the
USB-port
connectors
on
the
rear
of
your
server.
