Intel® Server Board S2600JF TPS Platform Management Functional Overview 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 Integrated 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 (both supporting encryption). 4.12.1.3 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. 4.12.1.4 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. 4.12.1.5 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 Integrated BMC reset (for example, due to an Integrated BMC Watchdog initiated reset or Integrated BMC reset after Integrated BMC firmware update) will require the session to be re-established. KVM sessions persist across system reset, but not across an AC power loss. 4.12.1.6 Timeout The remote KVM session will automatically timeout after a configurable amount of time (30 minutes is the default). The default inactivity timeout is 30 minutes, but may be changed through the embedded web server. Remote KVM activation does not disable the local system keyboard, video, or mouse. Remote KVM is not deactivated by local system input, unless the feature is disabled locally. 4.12.1.7 Usage Revision 1.3 53 Intel order number G31608-004
