Controls and LEDs This section describes the controls and light-emitting diodes (LEDs) on the blade server. You must open the door to access the controls and LEDs. Note: The control panel door is shown in the closed (normal) position in this illustration. You must open the control panel door to access the power-control button. CD/diskette/USB select button Blade-error LED Information LED Location LED Activity LED Power-on LED CD Keyboard/ mouse/ video select button Power-control button CD/diskette/USB select button: Press this button to associate the CD-ROM drive, diskette drive, and USB port with this blade server. The LED on this button flashes while the request is being processed, then is steady when the ownership of the CD-ROM drive, diskette drive, and USB port has been transferred to this blade server. It can take approximately 20 seconds for the operating system in this blade server to recognize the CD-ROM drive, diskette drive, and USB port. The operating system in the blade server must provide USB support for the blade server to recognize and use the CD-ROM drive, diskette drive, and USB port. The BladeCenter unit uses USB for internal communication with these devices. If there is no response when you press the CD/diskette/USB select button, you can use the management-module Web interface to see whether local control has been disabled on the blade server. Keyboard/mouse/video select button: Press this button to associate the keyboard port, mouse port, and video port with this blade server. The LED on this button flashes while the request is being processed, then is steady when the ownership of the keyboard, mouse, and video has been transferred to this blade server. It can take up to 20 seconds to switch the keyboard, video, and mouse control to the blade server. Although the keyboard that is attached to the BladeCenter unit is a PS/2®-style keyboard, communication with it is through the Universal Serial Bus (USB). The operating system in the blade server must provide USB support for the blade server to recognize and use the keyboard and mouse. The BladeCenter unit uses USB for internal communication with these devices. When you are running an operating system that does not have USB device drivers, the keyboard responds very slowly. 8 BladeCenter HS40 Type 8839: Hardware Maintenance Manual and Troubleshooting Guide

Press
this
button
to
associate
the
CD-ROM

port
with
this
blade
server.
The
LED
on
this
button
flashes
while
the
request
is
being
processed,
then
is
steady
when
the
ownership
of
the
CD-ROM
drive,
diskette
drive,
and
USB
port
has
been
transferred
to
this
blade
server.
It
can
take
approximately
20
seconds
for
the
operating
system
in
this
blade
server
to
recognize
the
CD-ROM
drive,
diskette
drive,
and
USB
port.
The
operating
system
in
the
blade
server
must
provide
USB
support
for
the
blade
server
to
recognize
and
use
the
CD-ROM
drive,
diskette
drive,
and
USB
port.
The
BladeCenter
unit
uses
USB
for
internal
communication
with
these
devices.
If
there
is
no
response
when
you
press
the
CD/diskette/USB
select
button,
you
can
use
the
management-module
Web
interface
to
see
whether
local
control
has
been
disabled
on
the
blade
server.

select
button:
Press
this
button
to
associate
the
keyboard
port,

processed,
then
is
steady
when
the
ownership
of
the
keyboard,

and
video
has
been
transferred
to
this
blade
server.
It
can
take
up
to
20
seconds
to
switch
the
keyboard,
video,
and
mouse
control
to
the
blade
server.
Although
the
keyboard
that
is
attached
to
the
BladeCenter
unit
is
a
PS/2
®
-style
keyboard,
communication
with
it
is
through
the
Universal
Serial
Bus
(USB).
The
operating
system
in
the
blade
server
must
provide
USB
support
for
the
blade
server
to
recognize
and
use
the
keyboard
and
mouse.
The
BladeCenter
unit
uses
USB
for
internal
communication
with
these
devices.
When
you
are
running
an
operating
system
that
does
not
have
USB
device
drivers,
the
keyboard
responds
very
slowly.
