System Board Connectors     21
Processor Slots (V, X, Y, AB)
Each Pentium
®
 II Xeon
 processor 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 MMX
 technology 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.
