the keyboard, mouse, and video has been transferred to this blade server. It can take approximately 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 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, such as in the following situations, the keyboard responds very slowly: v Running the blade server integrated diagnostics v Running a BIOS update diskette on a blade server v Updating the diagnostics on a blade server v Running the Broadcom firmware CD for a blade server If there is no response when you press the keyboard/mouse/video select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade server. You can also press keyboard keys in the following sequence to switch keyboard/mouse/video control between blade servers: NumLock NumLock blade_server_number Enter Where blade_server_number is the two-digit number for the blade bay in which the blade server is installed. If you install Microsoft Windows 2000 on the blade server while it is not the current owner of the keyboard, video, and mouse, a delay of up to 1 minute occurs the first time you switch the keyboard, video, and mouse to the blade server. During this one-time-only delay, the blade server device manager enumerates the keyboard, video, and mouse and loads the device drivers. All subsequent switching takes place in the normal keyboard-video-mouse switching time frame (up to 20 seconds). Power-control button: This button is behind the control panel door. Press this button to manually turn on or turn off the blade server. Note: The power-control button has effect only if local power control is enabled for the blade server. Local power control is enabled and disabled through the management-module Web interface. Power-on LED: This green LED indicates the power status of the blade server in the following manner: v Flashing rapidly - The service processor on the blade server is handshaking with the management module. v Flashing slowly - The blade server has power but is not turned on. v Lit continuously - The blade server has power and is turned on. Activity LED: When this green LED is lit, it indicates that there is hard disk drive, flash drive, or network activity. Chapter 2. Blade server power, controls, and indicators 17

the
keyboard,
mouse,
and
video
has
been
transferred
to
this
blade
server.
It
can
take
approximately
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
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,
such
as
in
the
following
situations,
the
keyboard
responds
very
slowly:
v
Running
the
blade
server
integrated
diagnostics
v
Running
a
BIOS
update
diskette
on
a
blade
server
v
Updating
the
diagnostics
on
a
blade
server
v
Running
the
Broadcom
firmware
CD
for
a
blade
server
If
there
is
no
response
when
you
press
the
keyboard/mouse/video
select
button,
you
can
use
the
management-module
Web
interface
to
determine
whether
local
control
has
been
disabled
on
the
blade
server.
You
can
also
press
keyboard
keys
in
the
following
sequence
to
switch
keyboard/mouse/video
control
between
blade
servers:
NumLock
NumLock
blade_server_number
Enter
Where
blade_server_number
is
the
two-digit
number
for
the
blade
bay
in
which
the
blade
server
is
installed.
If
you
install
Microsoft
Windows
2000
on
the
blade
server
while
it
is
not
the
current
owner
of
the
keyboard,
video,
and
mouse,
a
delay
of
up
to
1
minute
occurs
the
first
time
you
switch
the
keyboard,
video,
and
mouse
to
the
blade
server.
During
this
one-time-only
delay,
the
blade
server
device
manager
enumerates
the
keyboard,
video,
and
mouse
and
loads
the
device
drivers.
All
subsequent
switching
takes
place
in
the
normal
keyboard-video-mouse
switching
time
frame
(up
to
20
seconds).
Power-control
button:
This
button
is
behind
the
control
panel
door.
Press
this
button
to
manually
turn
on
or
turn
off
the
blade
server.
Note:
The
power-control
button
has
effect
only
if
local
power
control
is
enabled
for
the
blade
server.
Local
power
control
is
enabled
and
disabled
through
the
management-module
Web
interface.
Power-on
LED:
This
green
LED
indicates
the
power
status
of
the
blade
server
in
the
following
manner:
v
Flashing
rapidly
-
The
service
processor
on
the
blade
server
is
handshaking
with
the
management
module.
v
Flashing
slowly
-
The
blade
server
has
power
but
is
not
turned
on.
v
Lit
continuously
-
The
blade
server
has
power
and
is
turned
on.
Activity
LED:
When
this
green
LED
is
lit,
it
indicates
that
there
is
hard
disk
drive,
flash
drive,
or
network
activity.
