Chapter 2. Power, controls, and indicators Use this information to view power features, turn on and turn off the blade server, and view the functions of the controls and indicators. Blade server controls and LEDs Use this information for details about the controls and LEDs on the blade server. The following illustration identifies the buttons and information LEDs on the blade-server control panel. Power LED Activity LED Location LED Information LED Fault LED Power button NMI button KVM select button/LED Media-tray select button/LED Power-on LED: This green LED indicates the power status of the blade server in the following manner: v Flashing rapidly: While the service processor in the blade server is initializing and synchronizing with the management module, the power-on LED flashes rapidly, and the power-control button on the blade server does not respond. This process can take approximately two minutes after the blade server has been installed. If the LED continues to flash rapidly, the blade server might not have power permissions assigned to it through the Advanced Management Module, the BladeCenter unit does not have enough power to turn on the blade server, or the service processor (IMM) on the blade server is not communicating with the Advanced Management Module. v Flashing slowly: The blade server has power supplied and is ready to be 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 activity on the external storage device 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 lit, the location LED on the BladeCenter unit is also lit. The location LED can be turned off through the Advanced-Management-Module Web interface or through IBM® Director Console.

Power-on LED:
This green LED indicates the power status of the blade server in
the following manner:
v
Flashing rapidly: While the service processor in the blade server is initializing
and synchronizing with the management module, the power-on LED flashes
rapidly, and the power-control button on the blade server does not respond. This
process can take approximately two minutes after the blade server has been
installed. If the LED continues to flash rapidly, the blade server might not have
power permissions assigned to it through the Advanced Management Module,
the BladeCenter unit does not have enough power to turn on the blade server,
or the service processor (IMM) on the blade server is not communicating with
the Advanced Management Module.
v
Flashing slowly: The blade server has power supplied and is ready to be 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 activity on the
external storage device 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 lit, the location LED on the
BladeCenter unit is also lit. The location LED can be turned off through the
Advanced-Management-Module Web interface or through IBM
®
Director Console.
