Slot 2refers to the physical and electrical specification for the 330-leadSingle Edge Contact Cartridge(or edge-connector) used byIntel'sPentium II XeonandPentium III Xeon.

When first introduced,Slot 1Pentium IIswere intended to replace thePentiumandPentium Proprocessors in the home, desktop, and low-endsymmetric multiprocessing(SMP) markets. The Pentium II Xeon, which was aimed at multiprocessor workstations and servers, was largely similar to the ordinary Pentium II, being based on the sameP6Deschutescore, differing by offering the choice of L2 cache capacity of 1024 or 2048 KB besides 512 KB,and by operating it at the core frequency (the Pentium II used cheaper third-party SRAM chips, running at 50% of CPU speed, to reduce cost).

Because the design of the 242-lead Slot 1 connector did not support the full-speed L2 cache of the Xeon, an extended 330-lead connector was developed. This new connector, dubbed 'Slot 2', was used for Pentium II Xeon (codenamed 'Drake') and Pentium III Xeon (codenamed 'Tanner' and 'Cascades'). Slot 1 was finally replaced by theSocket 370with the revisedPentium IIIcodenamedTualatinfor the low power dual-processor servers, and Slot 2 bySocket 603withPentium 4-basedXeon (codenamed Foster)for workstations and quad-processor servers.
