outlets, wait until the power-on LED on the blade server flashes slowly before
pressing the blade server power-control button. During this time, the service
processor in the BladeCenter management module is initializing; therefore,
the power-control button on the blade server does not respond.
2. While the blade server is starting up, the power-on LED on the front of the
server is lit steady. See “Controls and LEDs” on page 8 for the power-on LED
states.
v
If a power failure occurs, the BladeCenter unit and then the blade server can
start automatically when power is restored (if the blade server is configured
through the BladeCenter management module to do so).
v You can turn on the blade server remotely by means of the service processor in
the BladeCenter management module.

v If your operating system supports the Wake on LAN
®
feature and the blade
server power-on LED is flashing slowly, the Wake on LAN feature can turn on the
blade server under the following conditions:
– The Wake on LAN feature has not been disabled through the
management-module Web interface.
– The blade server was previously turned on and the operating system was shut
down properly.
Turning off the blade server
When you turn off the blade server, it is still connected to power through the
BladeCenter unit. The blade server can respond to requests from the service
processor, such as a remote request to turn on the blade server. To remove all
power from the blade server, you must remove it from the BladeCenter unit.
Shut down your operating system before you turn off the blade server. See your
operating system documentation for information about shutting down the operating
system. Improper shutdown of a blade server will prevent that blade server from
being restarted using Wake on LAN.
The blade server can be turned off in any of the following ways:
v You can press the power-control button on the blade server (behind the control
panel door). This starts an orderly shutdown of the operating system, if this
feature is supported by your operating system.
Note: After turning off the blade server, wait at least 5 seconds before you press
the power-control button to turn on the blade server again.
v If the operating system stops functioning, you can press and hold the
power-control button for more than 4 seconds to turn off the blade server.
v The management module can turn off the blade server.
Note:
After turning off the blade server, wait at least 30 seconds for the hard disk
drives to stop spinning before you remove the blade server from the
BladeCenter unit.

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: 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.

Power-control button: This button is located behind the control panel door. Press
this button to manually turn the blade server on or off.
Note: This button has effect only if local power control is enabled for the blade
server. Local power control is enabled and disabled through the BladeCenter
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 BladeCenter 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 or
network activity.
Location LED: When this blue LED is lit, it has been turned on remotely by the
system administrator to aid in visually locating the blade server. The location LED
can be turned off through the BladeCenter management-module Web interface or
through the IBM Director Console.

v Running a BIOS update diskette on a blade server
v Updating the diagnostics on 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 see 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. A blade server that occupies more than one blade
bay is identified by the lowest bay number that it occupies.
If you install the Microsoft
®
Windows
®
2000 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 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).
Information LED: When this LED is lit, it indicates that a noncritical event has
occurred. A light path diagnostics LED on the processor board or I/O board is also
lit to help isolate the error. The information LED can be turned off through the
BladeCenter management-module Web interface or through the 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 will turn off only after the error is
corrected.
