Introduction

Installing a second processor increases the capabilities of your DIGITAL Server
3220/3220R. This chapter describes the configuration guidelines that must be
followed prior to upgrading your server as well as detailed procedures on removing
and installing a processor module.

Processor Configuration Guidelines

To upgrade to a dual processor configuration you must purchase and install a
processor upgrade kit. Contact your authorized DIGITAL sales representative for
more information.
Apply the following guidelines to your processor upgrade:
•
Single processor modules must be installed in the primary processor socket
(CPU1) and have a termination card installed in the second processor
socket (CPU2). The termination card must be removed prior to installing a
second processor.
•
If two processor are installed, they must be the same speed.
•
DIGITAL recommends that dual processor configurations use processors
with identical stepping (manufacturing revision). Processors with different
stepping might not function properly. You can use the processor ID number
that appears during the Power-On Self Test (POST) for each processor to
help you determine stepping. This information is found in the README files
on the Quick Launch CD-ROM discs.
