Lit continuously
: The blade server has power and is turned on.
When the blade server is on, pressing this button causes an orderly shutdown of the blade server so that
it is safe to remove. This includes shutting down the operating system (if possible) and removing power
from the blade server.
Note:
If you press the power button on the blade server that is part of a scalable blade complex running
as a single partition, both blade servers in the partition power on or shut down.
If an operating system is running, you might have to press the button for approximately 4 seconds to
initiate the shutdown.
Attention:
Pressing the button for 4 seconds forces the operating system to shut down immediately.
Data loss is possible.
KVM select button/LED
Press this button to associate the shared BladeCenter chassis keyboard, video, and mouse (KVM) ports
with the blade server. The LED on this button flashes while the request is being processed and then is lit
when the ownership of the keyboard, video, and mouse has been transferred to the blade server. It can
take approximately 20 seconds to switch the keyboard, video, and mouse control to the blade server.
Using a keyboard that is directly attached to the advanced management module, you can press
keyboard keys in the following sequence to switch KVM control between blade servers instead of using
the KVM select button:
NumLock NumLock
blade_server_number
Enter
Where
blade_server_number
is the two-digit number of the blade server bay in which the blade
server is installed. A blade server that occupies more than one blade server bay is identified by the
lowest bay number that it occupies.
If there is no response when you press the KVM select button, you can use the advanced management
module web interface to determine whether local control has been disabled on the blade server. See the
IBM BladeCenter Advanced Management Module: User's Guide
for more information.
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 MicrosoftWindows 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).
Media tray select button/LED
Press this button to associate the shared BladeCenter chassis media tray (removable-media drives) 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 advanced
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.
