At least one encryption level must be specified for the keyboard and mouse. When you specify
more than one SSL encryption type, the switch negotiates the strongest algorithm that is
supported by both sides. The strongest algorithm is AES, followed by 128 bit, 3DES and DES.
7. Click Save and then click Close. The Units View window will open.
To change the virtual media session settings on a KVM switch:
This procedure is valid for KVM switches that support virtual media.
1. In a Units View window containing appliances (see Accessing Units View windows on
page 106), click on the KVM switch name.
2. Click Appliance Settings in the side navigation bar and then click Sessions. The Appliance
Sessions window will open.
3. Click Settings in the side navigation bar and then click Virtual Media. The Appliance Virtual
Media Session Settings window will open.
4. In the Session Lock area, enable the Virtual Media locked to KVM session checkbox if you
wish to close the virtual media session when the associated KVM session is closed. When this
feature is disabled an active virtual media session will remain active when the associated KVM
session is closed.
5. In the Drive Mappings area, choose an access mode from the Virtual Media Access Mode
menu: read-only or read-write.
When the access mode is read-only, the user will not be able to write data to the mapped drive
on the client machine. When the access mode is read-write, the user will be able to read and
write data to the mapped drive.
If the drive is a read-only drive (for example, CD/DVD drives or ISO images), the access mode
setting will be ignored. If the drive on the client machine is read-write (for example, a mass
storage device or USB removal media), setting read-only access mode will prevent the user
from writing data to the client machine.
6. In the Encryption Level area, enable one or more encryption levels for the virtual media
session: DES, 3DES, 128-Bit SSL or AES. Any combination of selections (or no selection) is
valid.
7. If the KVM switch supports virtual media, the Virtual Media Access per IQ Module section
lists all USB2 or PS2M IQ modules. The list includes details about each IQ module, including
a virtual media status of Enabled or Disabled. The list of IQ modules may require multiple
pages; you can filter the list by column or click the arrows to move to a page. You can also
click Customize to specify what is displayed in this section. For information about filtering and
customizing, see Using Windows on page 26.
Select the checkbox next to each IQ module for which you want to enable/disable virtual
media and click Enable VM or Disable VM respectively. The preset virtual media status is
enabled.
