sessions).
• Lock Status - Whether KVM and virtual media sessions are locked. See Virtual media session

To disconnect one or more target device active sessions:
NOTE: To disconnect a session, a user must have unit view access rights and a preemption level that is greater
than or equal to the session user.
1. In a Units View window containing target devices (see Accessing Units View windows on
page 106), click on a target device Status field. The Active Sessions window for that target
device will open.
2. Click the checkbox to the left of the sessions. To disconnect all sessions, click the checkbox to
the left of Duration at the top of the list. (If you do not have permission to disconnect an active
session, you will not be able to select its checkbox or the checkbox at the top of the list.)
3. Click Disconnect. A confirmation dialog box will appear.
For virtual media sessions on supported KVM switches - If you attempt to disconnect an active
virtual media session or a KVM session that is locked to a virtual media session, a
confirmation message is displayed, indicating that any virtual media mappings will be
disconnected. Confirm or cancel. See Using Virtual Media on page 279.
4. Confirm or cancel the disconnect.
Active modem sessions
In the event the primary network fails, you may establish a session to an ACS console server
through a modem/ISDN dial-up connection method. This connection may be established using the
SSH Passthrough client or the ACS console server plug-in. To configure the SSH Passthrough
settings, see Enabling SSH Passthrough on page 195. To configure the ACS console server plug-in
settings, see the ACS console server plug-in online help.
Secure connections
During the initial dial-up connection attempt, the DSView 3 DialUp service will authenticate the
ACS console server and establish a connection using a Point-to-Point Protocol (PPP). Password
Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) are
supported. In addition to the PAP and CHAP methods, a One Time Password (OTP) authentication
may also be used for analog modem dial-up connections. (OTP is not supported on ISDN modems.)
A secret password will be generated for every dial-up request, and each password will only be valid
for a single attempt. Once authenticated, a secure connection will be established.
