CD-ROM drive is not
recognized after being
switched back to blade
server running Windows
2000 Advanced Server with
SP3 applied. (When the CD-
ROM drive is owned by
blade server x, is switched to
another blade server, then is
switched back to blade
server x, the operating
system in blade server x no
longer recognizes the CD-
ROM drive. This happens
when you have not safely
stopped the drives before
switching ownership of the
CD-ROM drive, diskette
drive, and USB port (media
tray).)
✏
NOTE
Because the SBCE unit uses a USB bus to communicate with
the media tray devices, switching ownership of the media tray
to another blade server is the same as unplugging a USB
device.
• Before switching ownership of the CD-ROM drive (media tray) to another
blade server, safely stop the media tray devices on the blade server that
currently owns the media tray, as follows:
1. Double-click the Unplug or Eject Hardware icon in the Windows
taskbar at the bottom right of the screen.
2. Select USB Floppy and click Stop.
3. Select USB Mass Storage Device and click Stop.
4. Click Close.
You can now safely switch ownership of the media tray to another blade
server.

Diskette drive problems
Symptom FRU/action
Diskette drive activity LED
stays on, or the system
bypasses the diskette drive. 1. If there is a diskette in the drive, verify that:
• The diskette is inserted correctly in the drive.
• The diskette is good and not damaged. (Try another diskette if you
have one.)
— The drive light comes on (one-second flash) when the diskette is
inserted.
• The diskette contains the necessary files to start the computer.
• The diskette drive is enabled in the Configuration/Setup utility
program.
• The software program is working properly.
• The cable is installed correctly (in the proper orientation).
2. To prevent diskette drive read/write errors, be sure the distance between
monitors and diskette drives is at least 76 mm (3 in.).
