	same as unplugging a USB device. Before switching ownership of the optical 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.

	Ethernet port designated as Planar Ethernet 2 is routed to Ethernet switch module 1.
	Verify the designations through your operating system settings or by testing:
	1.	Install only one switch module, in I/O-module bay 1.
	2.	Enable only one of the Ethernet controllers on the blade server. Make note of the
		designation the blade server operating system has for the controller.
	3.	Ping an external computer on the network connected to the switch module.
	If you can ping the external computer, the Ethernet controller you enabled is the
	upper controller in the blade server and is associated with Ethernet switch 1.

	blade servers but not to pinging the management module or objects connected to its
	external Ethernet port, such as the network management station. To get accurate
	results, always specify multiple repetitions (>1) in the ping request, and ignore the
	first ping response from that request. See the IBM 4-Port Gb Ethernet Switch Module
