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.
7.1.3 Security
The KVM redirection feature supports multiple encryption algorithms, including RC4 and AES. The actual
algorithm that is used is negotiated with the client based on the client’s capabilities.
7.1.4 Availability
The remote KVM session is available even when the server is powered-off (in stand-by mode). No re-start of
the remote KVM session shall be required during a server reset or power on/off. An BMC reset (e.g. due to an
BMC Watchdog initiated reset or BMC reset after BMC FW update) will require the session to be re-
established.
KVM sessions persist across system reset, but not across an AC power loss.
7.1.5 Usage
As the server is powered up, the remote KVM session displays the complete BIOS boot process. The user is
able interact with BIOS setup, change and save settings as well as enter and interact with option ROM
configuration screens.
At least two concurrent remote KVM sessions are supported. It is possible for at least two different users to
connect to same server and start remote KVM sessions
7.1.6 Force-enter BIOS Setup
KVM redirection can present an option to force-enter BIOS Setup. This enables the system to enter F2 setup
while booting which is often missed by the time the remote console redirects the video.
7.2 Media Redirection
The embedded web server provides a Java applet to enable remote media redirection. This may be used in
conjunction with the remote KVM feature, or as a standalone applet.
