Chapter 5. Sharing resources among the blade servers
Your
Eserver
BladeCenter Type 8677 unit provides resources that are available to
all blade servers at all times, such as power modules, cooling, system
management, and network switches; no user intervention is required. Some
resources are selectable for use by a single blade server at a time, such as the
CD-ROM drive, diskette drive, and USB port unit (media tray), or the
keyboard-video-mouse unit. There are two ways to select resources for a blade
server:
v
Each blade server has two selection buttons on the front of the blade:
CD
and
.
– To switch the keyboard, video, and mouse to a specific blade server, press
the button on that blade server.
– To switch the CD-ROM, diskette drive, and USB port to a specific blade
server, press the
CD
button on that blade server.
The management module immediately assigns the resource to the blade server
requesting it.
v You can use the management module Web interface to change ownership of the
keyboard, video, and mouse, or the CD-ROM drive, diskette drive, and USB port
(
Blade tasks → Remote control ).
v
Press keyboard keys in the following sequence to switch KVM control between
blade servers:
NumLock NumLock <blade server number> Enter
Where <blade server number> is the two-digit number for the blade bay in which
the blade server is installed.
You will need to press the Shift key to switch KVM control when using the
28L3644 (37L0888) keyboard. If the above key sequence does not switch KVM
control, do the following steps:
1. Press and hold the Shift key.
2. Press keyboard keys in the following sequence:
NumLock NumLock <blade server number> Enter
3. Release the Shift key.
Notes:
1. It can take approximately 20 seconds for the operating system in the
switched-to blade server to recognize the CD-ROM drive, diskette drive, and
USB port, or the keyboard, video, and mouse.
2. If you install Microsoft Windows 2000 on a blade server while it is not the
current owner of the keyboard, video, and mouse, the first time the blade server
requests ownership after the operating system has been installed, it can take up
to one minute for the operating system to recognize the devices (this is a
one-time-only occurrance).
3. 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.
4. You can use the management module Web interface to enable or disable the
select buttons ( Blade tasks → Remote control ) on the blade servers.
