Processors

The following paragraphs provide procedures for installing and removing the Pentium
II Xeon Processor Single Edge Contact (S.E.C.) cartridge. Use these procedures when
upgrading or replacing your processor(s). Each processor is packaged in a S.E.C.
cartridge. The cartridge includes the processor core with an integrated 16 KB primary
(L1) cache, secondary (L2) cache, heat sink, and a back cover. The processors are
supported by one or more voltage regulator modules (VRM) on the CPU baseboard,
depending on the number of installed processors.
Each S.E.C. cartridge installs in a Slot 2 connector on the CPU baseboard. Each slot
must contain either a processor cartridge or a termination board (if there are less than
four processors installed). The VRM modules are installed in a bank of VRM sockets
adjacent to the processors.
Note:
processors must be matched for speed. If replacing a processor, the
replacement processor must match the speed of all installed
processors. If upgrading a processor, all processors must be
upgraded to match.
Electrostatic discharge (ESD) can damage components; place them
on an antistatic surface. Update the CPU baseboard using an
antistatic wrist strap attached to chassis ground.
