ECG078/0698 TECHNOLOGY BRIEF (cont.) ... Integrated Management Display The IMD (Figure 13) is a backlit liquid crystal display (LCD) 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 13: Integrated Management Display with sample alert message. A 5V 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 both 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. Also during POST, all event logs, system information, and administrator information upload from the system nonvolatile RAM. During runtime, new events are stored in both 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 Application Specific Integrated Circuit (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 even if the OS is down. The administrator has the ability 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. Auto-Default ROM Configuration When the system is first powered on, the system ROM detects the unconfigured state of the hardware and provides default configuration settings for most devices. By providing this initialization, the system can run Diagnostics and other software applications before running the normal SmartStart and System Configuration applications. If the user inserts a System Configuration, Diagnostics, or SmartStart CD in the CD-ROM drive prior to powering on the server, the system ROM will boot using that CD. If the system ROM does not detect one of these CDs, the user will be prompted for the intended operating system. The system will reboot if any operating system-dependent configurations have changed with the new operating system selection. If the selected operating system-dependent configurations are the 19
