If there is no response when you press the KVM select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade server. Notes: 1. The operating system in the blade server must provide USB support for the blade server to recognize and use the keyboard and mouse, even if the keyboard and mouse have PS/2-style connectors. 2. If you install a supported Microsoft Windows operating system 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 that you switch the keyboard, video, and mouse to the blade server. All subsequent switching takes place in the normal KVM switching time frame (up to 20 seconds). Activity LED: When this green LED is lit, it indicates that there is activity on the hard disk drive or network. Location LED: The system administrator can remotely turn on this blue LED to aid in visually locating the blade server. When this LED is turned on, the location LED on the BladeCenter unit is also lit. The location LED can be turned off through the management-module Web interface or through IBM Director Console. Information LED: When this amber LED is lit, it indicates that information about a system error in the blade server has been placed in the management-module event log. The information LED can be turned off through the management-module Web interface or through IBM Director Console. Blade-error LED: When this amber LED is lit, it indicates that a system error has occurred in the blade server. The blade-error LED turns off only after the error is corrected. Media-tray select button: Press this button to associate the shared BladeCenter unit media tray (removable-media drives and front-panel USB ports) with the blade server. The LED on the button flashes while the request is being processed and then is lit when the ownership of the media tray has been transferred to the blade server. It can take approximately 20 seconds for the operating system in the blade server to recognize the media tray. If there is no response when you press the media-tray select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade server. Note: The operating system in the blade server must provide USB support for the blade server to recognize and use the removable-media drives and front-panel USB ports. Power-control button: This button is behind the control panel door. Press this button to 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.

system
in
the
blade
server
must
provide
USB
support
for
the
blade
server
to
recognize
and
use
the
keyboard
and
mouse,
even
if
the
keyboard
and
mouse
have
PS/2-style
connectors.

If
you
install
a
supported
Microsoft
Windows
operating
system
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
that
you
switch
the
keyboard,
video,
and
mouse
to
the
blade
server.
All
subsequent
switching
takes
place
in
the
normal
KVM
switching
time
frame
(up
