Solving Shared Media Tray Problems - IBM power PS700 Problem Determination And Service Manual

2. Verify that power management is set correctly for your BladeCenter unit configuration.
3. Verify whether the problem is being experienced on more than one blade server.
4. Perform a test of the failing function on a blade server that is known to be operational.
5. Try the blade server in a different blade bay.
6. Try a blade server that is known to be operational in the blade bay with the failing blade server.
7. Verify that the blade server and the monitor are powered on.
8. Check for problems with the media tray (removable media drives and USB ports), as described in

"Solving shared media tray problems."

9. Check for network connection problems, as described in "Solving shared network connection
problems" on page 225.
10. Check for power problems, as described in "Solving shared power problems" on page 225.
11. Check for video problems, as described in "Solving shared video problems" on page 226.
Solving shared media tray problems
Problems with BladeCenter shared resources might appear to be in the blade server, but might actually be
a problem in a BladeCenter unit media tray component.
To check the general function of shared BladeCenter media tray resources, perform the following
procedure.
1. Verify that the media-tray select button LED on the front of the blade server is lit.
A lit media-tray select button LED shows that the blade server is connected to the shared media tray.
2. Verify that the media tray devices work with another blade server.
3. Verify which components of the media tray are affected.
Components include:
v USB ports
v Diskette drive
v CD or DVD drive
4. Troubleshoot USB port problems if USB ports are the only failing component.
a. Make sure that the USB device is operational.
b. If using a USB hub, make sure that the hub is operating correctly and that any software the hub
requires is installed.
c. Plug the USB device directly into the USB port, bypassing the hub, to check its operation.
d. Reseat the following components:
v USB device cable
v Media tray cable (if applicable)
v Media tray
e. 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)
3) Media tray
