494 IBM BladeCenter JS23 and JS43 Implementation Guide
Consoles of the IBM BladeCenter JS23 and JS43
Like the previous JS12 and JS22 BladeCenter servers, the IBM BladeCenter
JS23 and JS43 blades have a graphics adapter. This graphics adapter makes it
possible to use the KVM switch that is built into the Advanced Management
Module to gain access to the console of the blade.
An alternative method to gain access to the console is the usage of Serial Over
LAN, or SOL.
You can use either the graphical console or the SOL console during POST. A
JS23/JS43 blade will start the first time as default with the graphical console as
long as you do not change this. The blade will ask, after first power on, which
console should be used as active console. If you miss this point during POST you
need to enter the System Maintenance Services menu from a graphical console
and change the console. See “System Management Services menu” on
page 501 for information about how to change the active console.
Graphical console
The graphical console is available by either using the connected keyboard,
display, and mouse on a management module installed in the BaldeCenter
chassis, or the remote control function of the Advanced Management Module.
Using keyboard, video, and mouse connected to a
management module to gain access to the graphical console
The physical console connected to a management module will most of the time
not be used. If you are working locally at the BladeCenter, you may use this
console to access blades. There is one analog console available that is switched
via the KVM switch that is built into the management module between the blades
in the chassis. To switch the console you may use the keyboard/video select
button that is placed on the front panel of each blade. Figure A-1 on page 495
shows the location of the front panel itself as well as the control elements on the
panel of an IBM BladeCenter JS23 and JS43.
