Device Suggested action
Pressing F1 brings up
browser help instead of
performing BladeCenter T
management functions.
Connecting to the BladeCenter T management module through the Web interface
does not provide proper coverage for the F1 key. In particular, pressing F1 to access
the Configuration/Setup Utility when a blade server is started brings up browser help
instead of the Configuration/Setup Utility.
This problem is peculiar to the Sun Java browser plug-in. Use the Microsoft virtual
machine (VM) that is built in to the browser.
Remote console has
keyboard entry problems with
Sun Java plug-
When you are redirecting the server console (remote console function) of a blade
server that is running Microsoft Windows 2000 or Windows XP and using the Sun
Java plug-in (Java Virtual Machine), the remote console can have keyboard entry
problems.
Use the Microsoft Java Virtual Machine (JVM) or Java Runtime Environment (JRE)
on the blade server instead of using the Sun Java Virtual Machine. The Microsoft
JVM comes with the Windows XP Service Pack 1. You can obtain the Microsoft JVM
for Windows 2000 from the Microsoft corporation. If you are using the Internet
Explorer browser version 6.0 or later to log into the management module and use the
remote control function, you must also adjust the browser settings:
1. Click Tools → Internet Options → Advanced tab.
2. Under the Java (Sun) section, uncheck the checkbox next to ’Use Java 2 v1.4. for
<applet> (requires restart)’
Management-module problems
The management module
password cannot be reset.
If you forget the management-module password, you will not be able to access the
BladeCenter T management module. The management-module password cannot be
overridden, and the management module will need to be replaced.
Management module does
not complete changeover to
redundant module on
hardware failure.
Replace the management module.
Media tray problems
Media tray access is lost
temporarily during
management module restart.
When the BladeCenter T management module is restarted, use of the media tray
(CD-ROM drive and USB ports) is lost temporarily. If you or a failure condition
initiates a management module restart while I/O activity is taking place on the media
tray, the disruption can interrupt reads to the CD-ROM drive or lose data being
written to a diskette.
Note: You can restart the management module through the Web interface to the
management module or from a network management station, such as the IBM
Director console. Some failures on the BladeCenter T unit can result in the
management module restarting automatically.
Make sure there is no I/O activity on the media tray before you restart the
management module.
Monitor problems
The monitor works when you
start the BladeCenter T unit,
but goes blank when you
start some application
programs in the blade
servers.
See the IBM 4-Port Gb Ethernet Switch Module for BladeCenter T Installation Guide
for instructions on how to ping through the Telnet interface.
