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
5. Troubleshoot the diskette drive if it is the only failing component. If there is a
diskette in the drive, make sure that:
v The diskette is inserted correctly in the drive.
v The diskette is good and not damaged; the drive LED light flashes once per
second when the diskette is inserted. (Try another diskette if you have one.)
v The diskette contains the necessary files to start the blade server.
v The software program is working properly.
v The distance between monitors and diskette drives is at least 76 mm (3 in).
6. Troubleshoot the CD or DVD drive if it is the only failing component.
v Verify that the CD or DVD is inserted correctly in the drive. If necessary,
insert the end of a straightened paper clip into the manual tray-release
opening to eject the CD or DVD. The drive LED light flashes once per
second when the CD or DVD is inserted.
v Verify that the CD or DVD is clean and not damaged. (Try another CD or
DVD if you have one.)
