Keyboard or mouse problems
Use this information to diagnose and resolve keyboard and mouse issues.
To check for keyboard or mouse problems, complete the following steps until the problem is solved:
Step 1. Make sure that:
• Both the blade server and the monitor are turned on.
• The keyboard/video/mouse select button LED on the front of the blade server is lit, indicating
that the blade server is connected to the shared keyboard and mouse.
• The keyboard or mouse cable is securely connected to the active BladeCenter advanced
management module.
• The keyboard or mouse works with another blade server.
Step 2. Check for correct advanced management module operation (see the documentation for your
BladeCenter chassis).
Note:
Some BladeCenter chassis types have several management-module components that might
have to be tested or replaced (see the
Installation Guide
for your advanced management module
for more information).
Step 3. Replace the keyboard or mouse.
Step 4. Replace the advanced management module (see the documentation for your BladeCenter chassis).
If these steps do not solve the problem, it is likely a problem with the blade server. See “Keyboard or mouse
problems” on page 256.
Media tray problems
Use this information to diagnose and resolve media tray issues for the blade server.
To check for problems with the media tray (removable media drives and USB ports), complete the following
steps until the problem is solved:
Step 1. Make sure that:
• The media-tray select button LED on the front of the blade server is lit, indicating that the blade
server is connected to the shared media tray.
• The media tray devices work with another blade server.
Step 2. Determine whether the problem affects more than one media tray component:
• USB ports
• CD or DVD drive
Step 3. For problems that affect only a USB port:
a. Make sure that the USB device is operational. If you are using a USB hub, make sure that the
hub is operating correctly and that any software that the hub requires is installed. Connect the
USB device directly to the USB port, bypassing the hub, to check its operation.
b. Reseat the following components:
1. USB device cable
2. Media tray cable (if applicable)
3. Media tray
c. Replace the following components one at a time, in the order shown, restarting the blade
server each time:
1. USB cable (if applicable)
2. Media tray cable (if applicable)
