TECHNOLOGY BRIEF (cont.) TCP/IP - transmission control protocol/internet protocol TC000603TB ... Integrated Management Display The IMD (Figure 12) is a backlit liquid crystal display that allows administrators to enter server and contact information. Just as importantly, the IMD displays critical information, warning messages, and error messages in an easy-to-understand format. 11:21 AM Fan Removed Main System: Fan ID: 2 Figure 12: Integrated Management Display with sample alert message. A 5-volt auxiliary power line supplies power to the IMD whenever the server power line is plugged in. Even if the server power goes down, the auxiliary line continues to power the IMD so that critical information, such as the last error message and the administrator's name, can be obtained. The IMD unit contains its own static memory. This memory contains the software code to control the IMD and the text messages shown on the display. All software enhancements added in the future will be available through a flashable ROMPaq. During POST, all event logs, system information, and administrator information are uploaded from the system nonvolatile RAM. During runtime, new events are stored in the nonvolatile RAM and the IMD SRAM. If the IMD unit is removed and replaced, all key event and system information is still available. Integrated Remote Console IRC consists of a Compaq designed ASIC and associated firmware. IRC allows out-of-band, or asynchronous, management capabilities such as remote console and remote reset. These capabilities are independent of the state of the network OS. With IRC, an administrator has full text mode video and keyboard access to access the server, perform diagnostics, reset the system, watch the reset process remotely, and view reset sequences, regardless of whether the OS is functional. For more information about IRC, refer to the Compaq technology brief Remote Server Management with Integrated Remote Console, document number 582A/1096. Remote Insight Board/PCI Option The optional Remote Insight Board/PCI provides seamless remote access and control independent of both the server OS and the server hardware. The Remote Insight Board/PCI is also fully integrated with Compaq Insight Manager. An administrator can remotely access the Remote Insight menu through the Insight Manager interface or through a web browser. The web browser uses the PPP dial-in connection with its user authentication and security features or a TCP/IP connection, rather than an unsecured Internet web connection. Like IRC, the Remote Insight Board/PCI can be used when the server OS is not functioning. Unlike IRC, Remote Insight can be used even when the server hardware is not functioning or power is lost. If a server power loss occurs, Remote Insight's battery backup provides power for at least 30 minutes-long enough to send out power-down alerts. 21
