Memory problems
Suggested action
If the wrong language is displayed, update the firmware or operating system with the
correct language in the blade server that has ownership of the monitor.
If the problem remains, call for service.
v Make sure that the mouse cable is securely connected to the BladeCenter
management module, and that the keyboard and mouse cables are not reversed.
v Verify that the mouse works correctly with other blade servers.
v Verify that the mouse is recognized as a USB device, not PS2, by your blade
server. Although the mouse is a PS2-style device, communication with the mouse
is through an internal USB bus in the BladeCenter chassis. Some operating
systems permit you to select the type of mouse during installation of the operating
system. Select USB.
If the problem remains, call for service.
Verify that:
1. The power LED on the front of the BladeCenter unit is on.
2. The LEDs on all the BladeCenter power modules are on.
3. If the blade server or attached storage expansion unit is in blade bay 7-14, power
modules are in power bays 1, 2, 3 and 4.
4. The power-on LED on the blade server control panel is blinking slowly.
v If the power LED is blinking rapidly and continues to do so, the blade server is
not communicating with the management module; reseat the blade server.
v If the power LED is off, the blade bay is not receiving power or the blade
server is defective; call for service.
5. Local power control for the blade server is enabled (use the BladeCenter
management module Web interface to verify), or the blade server was instructed
through the management module (Web interface or IBM Director) to turn on.
If you just installed an option in the blade server, remove it, and restart the blade
server. If the blade server now turns on, you might have installed more options than
the power to that blade bay supports.
Try another blade server in the blade bay.
If the problem remains, call for service.
