Notes:
1. The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard, mouse, CD-ROM drive, and
diskette drive. The BladeCenter unit uses USB for internal communication with
these devices.
2. Although the keyboard attached to the BladeCenter unit is a PS/2
keyboard, communication with it is through a USB bus. When you are running
an operating system that does not have USB drivers, such as in the following
instances, the keyboard responds very slowly.
v Running the blade server integrated diagnostics
v Running a BIOS update diskette on a blade server
v Updating the diagnostics on a blade server
v Running the Broadcom firmware CD for a blade server
3. If you install Microsoft
current owner of the keyboard, video, and mouse, a delay of up to one minute
occurs the first time you switch the keyboard, video, and mouse to the blade
server. During this one-time-only delay, the blade server Device Manager
enumerates the keyboard, video, and mouse and loads the device drivers. All
subsequent switching takes place in the normal keyboard-video-mouse
switching time frame (up to 20 seconds).
4. The blade-error LED, information LED, and location LED can be turned off
through the BladeCenter management-module Web interface or the IBM
Director console. The IBM Director program is a system-management product
that comes with the BladeCenter unit.
