The Compaq ProLiant 7000 and ProLiant 6500 servers are the first standards-based servers to incorporate industry-standard PCI Hot Plug technology. This technology, pioneered by Compaq, adds hot-plug capabilities to existing PCI adapters for increased system availability and serviceability.

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.

OS selection may be changed during subsequent reboots. SERVICEABILITY FEATURES By providing easy access to server components, the ProLiant 7000 design further reduces the downtime associated with upgrades and field maintenance. The processor board, memory boards, and the I/O board are mounted using - Compaq ProLiant 7000 | Compaq ProLiant 7000 Server Technology - Page 21
bus it supports create more power and thermal load than the current Pentium Pro-based systems. In planning for the Pentium II Xeon processor and 4-way requirements, Compaq engineered the ProLiant 7000 power supplies and chassis with "headroom" to accommodate this additional load.

board, the I/O board, and the I/O slots. Processor Board The ProLiant 7000 processor board is placed on a sheet metal subpan, as shown in Figure 15. The ProLiant 7000 Pentium Pro-based servers can be adapted to a new Pentium II Xeon-based system by simply removing the old subpan and sliding the new - Compaq ProLiant 7000 | Compaq ProLiant 7000 Server Technology - Page 23
panel inserts can be replaced to upgrade server. CONCLUSION As business requirements become more demanding, Compaq will continue to deliver servers that meet those requirements and that can be expanded to meet future needs as well. The ProLiant 7000 offers many hot-plug and redundant technologies

Compaq ProLiant 7000 Server Technology
This technology brief describes the high-performance, high-availability, and management
technologies built into the Compaq ProLiant 7000 Server.
The high-performance
technologies include Intel’s 32-bit Pentium® II Xeon™ processor, as well as
improvements to the ProLiant 7000’s PCI bus architecture.
Compaq has fulfilled its
promise to extend the functionality of the ProLiant 7000 by providing an upgrade path to
four or eight Pentium II Xeon processors.
The high-availability technologies include: PCI Hot Plug technology, redundant network
interface controllers, redundant hot-plug power supplies, drives, and fans; and
redundant processor power modules.
The ProLiant 7000 design also contains easy-
access components that reduce downtime for service or upgrades.
The ProLiant 7000
incorporates key management technologies, such as the Integrated Management Display,
Integrated Remote Console, and Auto-Default ROM Configuration, that further enhance
availability.
The intended audience for this paper is the engineer or system administrator familiar
with existing Compaq technology and servers.
For those less familiar with Compaq
technology, please see the related technology briefs referenced in this document.
