Remote Console KVM operation, Main window | Lenovo TD230 specification

Chapter 5. Remote Console (KVM) operation

The Remote Console is the redirected screen, keyboard and mouse of the remote host system where the Remote Management Module is installed. To use the Remote Console window of your managed host system, the browser must include a Java* Runtime Environment plug-in. If the browser has no Java support, such as with a small handheld device, the user can maintain the remote host system using the administration forms displayed by the browser.

Starting the Remote Console opens a new window to display the screen content of the host system. The Remote Console acts as if the administrator were sitting directly in front of the screen of his/her remote system. This means the keyboard and mouse can be used in the usual way.

Launch the redirection console

The Remote Console is the redirected keyboard, video and mouse of the remote host system where the Remote Management Module is installed. Launch the remote console KVM redirection window from this page.

Step 1. Click Launch Console to launch the redirection console and remotely manage the server.

Step 2. A pop-up window is displayed and begins to download the Java Network Launch Protocol — jviewer.jnlp file. This in turn downloads the standalone Java application implementing the Remote Console.

Both Microsoft Internet Explorer and Mozilla Firefox browsers are supported.

Notes:

•You must install the Java Run-Time Environment (JRE, version 6 update 10 or later) on the client prior to the launch of a JNLP file.

•The client browser must allow pop-up windows from the Remote Management Module IP address.

The Remote Console window is a Java Applet that establishes TCP connections to the Remote Management Module module. The protocol that is run over these connections is a unique KVM protocol and not HTTP or HTTPS. This protocol uses ports #7578 for KVM, #5120 for CDROM media redirection, and #5123 for Floppy/USB media redirection. Your local network environment must permit these connections to be made, i.e. your firewall and, in case you have a private internal network, your NAT (Network Address Translation) settings have to be configured accordingly.

Main window

Starting the Remote Console opens an additional window.

The window displays the screen content of your remote server. The Remote Console will behave as if you were located at the remote server. The responsiveness may be slightly delayed depending on the bandwidth and latency of the network between the Remote Management Module and Remote Console. Enabling KVM and/or media encryption on the Configuration ➙ Remote Session web page will degrade performance as well.

The Remote Console window always shows the remote screen in its optimal size. This means it will adapt its size to the size of the remote screen initially and after the screen resolution of the remote screen has been changed. However, you can always resize the Remote Console window in your local window as usual.
