Remote Insight provides several important troubleshooting features that none of the other Compaq tools can. Remote Insight provides both numeric and alphanumeric paging. Other essential troubleshooting features are provided by Remote Insight through its multiple diagnostic capabilities. It captures videotext of the last two reset sequences in addition to the last failure sequence. It can also access several management logs that are unavailable through IRC. For additional information about the Remote Insight Board/PCI, see the white paper Compaq Remote Insight Board/PCI: Hardware and Software Architecture, document number ECG072/0798. SERVICEABILITY FEATURES The ProLiant 8500 server defines a new level of serviceability with a unique modular design that includes five components: the processor/memory module, the media module, the I/O module, the power supplies, and a system midplane. As shown in Figure 13, the removable, drawer-like modules and power supplies connect to a common system midplane. This virtually cable-free design eases serviceability and future upgrades, since a module can be removed and replaced with little effort.

The system midplane is the backbone of the ProLiant 8500 server: all power and signals pass through it. The midplane is held in place with two thumbscrews and allows a virtually cable-free design and tool-free serviceability. High-density connectors and a positive interlocking mechanism allow the midplane to provide a highly reliable interconnect. The design of the chassis has been enhanced with a sliding top access panel that provides easy access to the I/O module and the processor and memory module. The modularity of the ProLiant 8500 server permits the chassis to be emptied completely to eliminate heavy lifting. Cam levers allow each module to be easily removed, and four lift assist handles make rack mounting the 22
