4-10 Upgrading Your System
Installing/Removing the Processor Cartridge
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 system board, depending on the
number of installed processors.
Each S.E.C. cartridge installs in a Slot 2 connector on the 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: Your system may have up to four processors. 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 system
board using an antistatic wrist strap attached to chassis
ground.
!
WARNING
If the system was running, any processor and heat sink
installed on the board is hot. To avoid the possibility of a
burn, let the components cool for 10 minutes before
continuing with these procedures.
Installing a Processor Cartridge
Use the following procedure to install a processor cartridge.
Note: All installed processors must be matched in
speed. If your system has less than four processors, and
you are adding one, then you must remove the termination
board in the empty Slot 2 connector. Remove a termination
board the same way as a cartridge.
