Escala BL460 - Problem Determination and Service Guide
Using a keyboard that is directly attached to the management module, you can press keys
in the following sequence to switch keyboard and video 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. When you use some keyboards, such as the 28L3644
(37L0888) keyboard, hold down the Shift key while you enter this key sequence.
If there is no response when you press the keyboard/video select button, you can use the
Web interface of the management module to determine whether local control has been
disabled on the blade server.
2 Media-tray select button:
Press this button to associate the shared Bull Blade Chassis - Enterprise media tray
(removable-media drives and front-panel USB ports) with the blade server. The LED on the
button flashes while the request is being processed, then is lit when the ownership of the
media tray has been transferred to the blade server. It can take approximately 20 seconds
for the operating system in the blade server to recognize the media tray.
If there is no response when you press the media-tray select button, use the management
module to determine whether local control has been disabled on the blade server.
Note The operating system in the blade server must provide USB support for the blade
server to recognize and use the removable-media drives and USB ports.

When this amber LED is lit, it indicates that information about a system error for the blade
server has been placed in the management-module event log. The information LED can be
turned off through the Web interface of the management module or through IBM System
Director Console.
4 Blade-error LED:

• Correcting the error.
•
Reseating the blade server in the Bull Blade Chassis - Enterprise.
•
Cycling the Bull Blade Chassis - Enterprise power.
