1 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, 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, use the management module 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 USB ports.
2 Information LED: When this amber LED is lit, it indicates that information about a system error for
the blade server has been placed in the management-module event log. The information LED can be
turned off through the Web interface of the management module or through IBM Director Console.
3 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 after one of the following events:
v Correcting the error
v Reseating the blade server in the BladeCenter unit
v Cycling the BladeCenter unit power
4 Power-control button: This button is behind the control panel door. Press this button to turn on or
turn off the blade server.
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 Web interface of the management module.
Press the power button for 5 seconds to begin powering down the blade server.
5 NMI reset (recessed): The nonmaskable interrupt (NMI) reset dumps the partition. Use this recessed
button only as directed by IBM Support.
6 Power-on LED: This green LED indicates the power status of the blade server in the following
manner:
v Flashing rapidly: The service processor is initializing the blade server.
v Flashing slowly: The blade server has completed initialization and is waiting for a power-on command.
v Lit continuously: The blade server has power and is turned on.
Note: The enhanced service processor can take as long as three minutes to initialize after you install the
BladeCenter PS700 blade server, at which point the LED begins to flash slowly.
