v Large system memory
The memory bus in your blade server supports up to 4 GB (8 GB with availability
of 2 GB DIMMs) of system memory. The memory controller provides support for
up to four industry-standard 2.5 V, 184-pin, double-data-rate (DDR), PC2100,
registered synchronous dynamic random-access memory (SDRAM) with error
correcting code (ECC) DIMMs. For the most current list of supported DIMMs, see
the Server Proven list.
v Light Path Diagnostics
The Light Path Diagnostics feature provides LEDs to assist in isolating problems
with the blade server. An LED on the blade server control panel is lit if an
unusual condition or a problem occurs. If this happens, you can look at the LEDs

System-board LED locations
The following illustration shows the location of the LEDs on the system board. You
might need to refer to this illustration when solving problems with the blade server.
You need to remove the blade server from the BladeCenter unit, open the cover,
and press the Light Path Diagnostics button to light any error LEDs that were
turned on during processing.
Note: Power is available to relight the Light Path Diagnostics LEDs for a short
period of time after the blade server is removed from the BladeCenter unit.
During that period of time, you can relight the Light Path Diagnostics LEDs
for a maximum of 25 seconds (or less, depending on the number of LEDs
that are lit and the length of time the blade server is removed from the
BladeCenter unit) by pressing the Light Path Diagnostics button. The Light
Path Diagnostics power present LED (CR111) lights when the Light Path
Diagnostics button is pressed if power is available to relight the blade-error
LEDs. If the Light Path Diagnostics power present LED does not light when
the Light Path Diagnostics button is pressed, no power is available to light
the blade-error LEDs and they will be unable to provide any diagnostic
information.

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 powering up, the power-on LED on the front of the
server is lit. See “Blade server controls and LEDs” on page 15 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, if the Wake on LAN feature has not been disabled through the
management-module Web interface.

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.
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 its hard disk
drives to stop spinning before you remove the blade server from the
BladeCenter unit.

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 up to 20 seconds for the operating system in this blade server to
recognize the CD-ROM drive, diskette drive, and USB port.
If there is no response when you press the CD/diskette/USB select button, you can
use the management-module Web interface to see if local control has been
disabled on the blade server.
Blade-error LED: When this amber LED is lit, it indicates that a system error has
occurred in the blade server.
Information LED: When this amber LED is lit, it indicates that information about a
system error for this blade server has been placed in the BladeCenter system error
log.
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
on the BladeCenter unit will be lit also.
Activity LED: When this green LED is lit, it indicates that there is hard-disk-drive or
network activity.
Chapter 2. Blade server power, controls, and indicators 15
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 ac power but is not turned on.
v Lit continuously - The blade server has ac power and is turned on.
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.
If there is no response when you press the keyboard/mouse/video select button,
you can use the management-module Web interface to see if 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.
Power-control button: This button is behind the control panel door. Press this
button to manually turn the blade server on or off.
Note: The power-control button has effect only if local power control is enabled for
