Processor Slots (V, X, Y, AB)

Each Pentium® II Xeonprocessor is packaged in a SEC cartridge. The cartridge includes the processor core with an integrated 16 KB primary (L1) cache; the secondary (L2) cache; a thermal plate; and a back cover.

The processor implements MMXtechnology and maintains full

backward compatibility with the 8086, 80286, Intel386, Intel486, Pentium, and Pentium Pro processors.

Each SEC cartridge connects to the system board through a Slot 2 edge connector. The cartridge is secured by a retention bracket attached to the system board. Depending on configuration, the server has one to four processors.

The processor external interface is multiprocessor (MP)-ready and operates at 100 MHz. The processor contains a local advanced programmable interrupt controller (APIC) for interrupt handling in MP and uniprocessor (UP) environments. The system SMP design supports up to four processors and is Intel MP Specification v1.1 and 1.4 compliant.

The second-level cache is located inside the SEC cartridge. The cache includes burst pipelined synchronous static RAM (BSRAM) and is offered in 512 KB, 1 MB, and 2 MB configurations, with ECC that operates at the full core clock rate.

Each processor cartridge requires two VRMs to provide power to the processor core and the second-level cache, respectively. The full details of the installation of processors and VRMs are provided in “VRM Connectors (P, Q, R, S, T, U)” on page 20.

Power Connectors

There are several power connectors that provide power for the system board. Some of these connectors provide power for specialized functions.

Main Power Connector, Primary (W)

The primary power connectors provide the majority of the power to the system board. These connectors are designed to accommodate the power supply installed in the system.
