8 Deploying Samba on IBM Eserver BladeCenter
Like the IBM Eserver BladeCenter’s media tray, this control panel also has system
information LEDs. The only difference is that the blade’s panel also has control switches,
which are detailed below.
Media-select button Press this button to associate the CD-ROM drive, diskette drive,
and USB port with this blade server. This button lights when the
ownership of the CD-ROM drive, diskette drive, and USB port
transfers to this blade server.
Blade-error This LED is also known as the blade system-error LED. When this
amber LED is on, it indicates a system error has occurred in the
blade.
Information When this amber LED is on, it indicates information about a system
error for this server has been placed in the BladeCenter System
Error log.
Location This blue LED is turned on in response to a programmed condition,
or remotely by the system administrator, to aid in blade
identification for maintenance. The location LED on the
IBM Eserver BladeCenter will be on also. Turn off the location
LED after maintenance is complete.
Activity When this green LED is on, it indicates that there is activity in the
blade server; this includes hard disk and network activity.
Power-on While the IBM Eserver BladeCenter has AC power, this green
LED turns on and stays on when you turn on your blade server.
Console select button Press this button to associate the keyboard, mouse, and video
ports with this blade server. This button lights when the ownership
of the keyboard, mouse, and video transfers to this blade server.
Power-control button This button is located behind the control panel door. Press this
button to manually turn the blade server on or off.
1.2.3 BladeCenter Management Module
The BladeCenter Management Module’s primary function is to provide systems management
for your IBM Eserver BladeCenter and blade servers, but it does have other important
functions such as multiplexing the keyboard/video/mouse (KVM) to provide a local console
for the individual blade servers and configuring the BladeCenter unit and switch modules. The
management module communicates with all of the key components of the IBM Eserver
BladeCenter including the switch, power and blower modules, as well as the blade servers
themselves. The management module detects the presence, absence and condition of each
of these components. A picture of the BladeCenter Management Module is shown in
Figure 1-6 on page 9.
Note: The power-control button only has effect if the local power control option is enabled
via the Management Module.
