(media-r). This feature allows a user to interactively use the keyboard, video, and mouse (KVM) functions of
the remote server as if the user were physically at the managed server.
KVM redirection console support the following keyboard layouts: English, Dutch, French, German, Italian,
Russian, and Spanish.
KVM redirection includes a “soft keyboard” function. The “soft keyboard” is used to simulate an entire
keyboard that is connected to the remote system. The “soft keyboard” functionality supports the following
layouts: English, Dutch, French, German, Italian, Russian, and Spanish.
The KVM-redirection feature automatically senses video resolution for best possible screen capture and
provides high-performance mouse tracking and synchronization. It allows remote viewing and configuration in
pre-boot POST and BIOS setup, once BIOS has initialized video.
Other attributes of this feature include:
 Encryption of the redirected screen, keyboard, and mouse
 Compression of the redirected screen.
 Ability to select a mouse configuration based on the OS type.
 supports user definable keyboard macros.
KVM redirection feature supports the following resolutions and refresh rates:
• 640x480 at 60Hz, 72Hz, 75Hz, 85Hz, 100Hz
• 800x600 at 60Hz, 72Hz, 75Hz, 85Hz
• 1024x768 at 60Hx, 72Hz, 75Hz, 85Hz
• 1280x960 at 60Hz
• 1280x1024 at 60Hz
• 1600x1200 at 60Hz
• 1920x1080 (1080p),
• 1920x1200 (WUXGA)
• 1650x1080 (WSXGA+)
7.1.1 Remote Console
The Remote Console is the redirected screen, keyboard and mouse of the remote host system. 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.
The Remote Console window is a Java Applet that establishes TCP connections to the BMC. 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. When
encryption is enabled, the protocol uses ports #7582 for KVM, #5124 for CDROM media redirection, and
#5127 for Floppy/USB media redirection. The local network environment must permit these connections to be
made, i.e. the firewall and, in case of a private internal network, the NAT (Network Address Translation)
settings have to be configured accordingly.
7.1.2 Performance
The remote display accurately represents the local display. The feature adapts to changes to the video
resolution of the local display and continues to work smoothly when the system transitions from graphics to text
or vice-versa. The responsiveness may be slightly delayed depending on the bandwidth and latency of the
network.
Enabling KVM and/or media encryption will degrade performance. Enabling video compression provides the
fastest response while disabling compression provides better video quality.
For the best possible KVM performance, a 2Mb/sec link or higher is recommended.
The redirection of KVM over IP is performed in parallel with the local KVM without affecting the local KVM
operation.
