4-18 Upgrading Your System
Processors
The following sections provide procedures for installing and removing the
Pentium
III 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 backboard, depending on the number of installed
processors.
Each S.E.C. cartridge installs in a Slot 2 connector on the CPU backboard. 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:
Your system may have up to four processors on
a CPU backboard and up to eight processors if a second
CPU backboard is installed. All installed 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.
!
CAUTION
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.
!
WARNING
If the system was running, any processor and heat sink
installed is hot. To avoid the possibility of a burn, let the
components cool for 10 minutes before continuing with these
procedures.
