User guide

You can also select the keyboard language for the local port, scan mode time, enable/disable the setup port
password and select a user preemption level. The preemption level of users determines whether they may
disconnect another user’s serial or KVM session with a target device. Preemption levels range from 1 - 4, with 4
being the highest level. For example, a user with a preemption level of 4 may preempt other level 4 users, as
well as those with a level 1, 2 or 3 setting.
To change the default preemption level (administrator only):
1. From the side navigation bar, select Unit View - Appliance - Appliance Settings - Ports - Local Port UI to
open the Local Port UI Settings screen.
2. Select or deselect the Disable Local Port User Authentication checkbox.
3. Select one of the following options from the User Access Level drop-down menu:User, User Administrator
or Appliance Administrator.
4. Select a number 1 - 4 from the User Preemption Level drop-down menu.
5. Click Save.
Virtual Media
You can determine the behavior of the switch during a virtual media session using the options provided in the
Appliance Virtual Media Session Settings screen. Table 3.4 outlines the options that can be set for virtual media
sessions.
For information about using virtual media in a KVMsession, see Virtual Media on page 41.
Setting Description
Session Settings:
Virtual Media
locked to KVM
session
The locking option specifies whether a virtual media session is locked to the KVM session on the
target device. When locking is enabled (default) and the KVM session is closed, the virtual media
session will also be closed. When locking is disabled and the KVM session is closed, the virtual media
session will remain active.
Session
Settings:Allow
Reserved
Sessions
Ensures that a virtual media connection can only be accessed with your username and that no other
user can create a KVM connection to that target device. When the associated KVM session is
disconnected, the virtual media session may be disconnected according to the Locked setting in the
Virtual Media dialog box.
Drive Mappings:
Virtual Media
Access Mode
You may set the access mode for mapped drives to 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 server. When the
access mode is read-write, the user will be able to read and write data from/to the mapped drive. If
the mapped drive is read-only by design (for example, certain CD/DVD drives or ISO images), the
configured read-write access mode will be ignored. Setting the read-only mode can be helpful when
a read-write drive such as a mass storage device or a USB removable media is mapped, and you
wish to prevent the user from writing data to it.
Encryption Level
You may configure encryption levels for virtual media sessions. The choices are: None (default), 128-
bit SSL(ARCFOUR), DES, 3DES and AES.
Virtual Media
Access per
IQModule:Enable
VM/Disable VM
If the MergePoint Unity 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. You can either enable or disable virtual media for each
IQmodule. If the KVM switch does not support virtual media, this section and associated buttons and
links are not displayed.
