Using Virtual Media 63

o

Locked–Synchronizes the KVM and Virtual Media sessions so that when a user disconnects a

KVM connection, the Virtual Media connection to that server is also disconnected. A local user
attempting to switch to a different server is also disconnected. The Reserve option overrides the

Locked option.

o

Reserve–A Virtual Media connection can be accessed only with the user name and no other user
can create a KVM connection to that server. The Reserve option overrides the Locked option.

o

CD ROM–Enables Virtual Media sessions to the first detected CD drive. Select this checkbox to
establish a Virtual Media CD connection to a server. Clear this checkbox to end a virtual media

CD connection to a server.

o

Mass Storage–Enables Virtual Media sessions to the first detected mass storage drive. Select this
checkbox to establish a Virtual Media mass storage connection to a server. Clear this checkbox

to end a Virtual Media mass storage connection to a server.

o

Write Access–Enables a target server to write data to the Virtual Media during a Virtual Media
session. Read access is always enabled during a Virtual Media session.

Using USB composite media devices

The Virtual Media interface adapters are USB composite devices that present one CD or DVD drive and

one mass storage (floppy, USB key, and so on) device. Each Virtual Media session is static (not dynamic),

which means you cannot change the device that you are mapping until the current session has ended.

You can change the device through the local KVM menu interface or by manually removing the device
from the console switch.
If you map a Virtual Media session using another composite USB device (such as a composite USB key)

then the same conditions apply. The first device of each type to be presented for mapping is recognized

and all subsequent devices are ignored. For example, if you use a USB key to boot as either a USB floppy
or USB hard disk drive, the ability to map each device depends upon the order in which each device is

presented.
Because local Virtual Media functionality does not distinguish between types of mass storage, Windows®

recognizes each device as removable storage, regardless of how each device is presented.

Disabling the USB 2.0 function

If your target server BIOS or operating system does not support USB 2.0 devices or composite USB 2.0

devices, you must disable the USB 2.0 function of the USB 2.0 interface adapter with Virtual Media from
the console switch local OSD, allowing the interface adapter to operate in 1.1 mode. You should limit the

interface adapter to USB 1.1 speed only if the interface adapter functionality is not working properly. The

interface adapter functionality is not working properly, for example, if the keyboard and mouse are not

working properly, if the server hangs while booting up, if an installation program fails, or if Virtual Media

is not working properly.
