iv ABOUT THIS GUIDE

1INTRODUCTION
General The CoreBuilder 7000HD Switch Engine 32MB Memory Upgrade Kit
(3C37041) increases the ATM switching capacity, measured in calls,
by a factor of four to five. This upgrade is available in conjunction
with the CoreBuilder 7000 family software version 4.0, and replaces
the existing 16MB memory included on the switch board.
Installation of the memory upgrade is simple, and no other
modifications are required. Software version 4.0 automatically
recognizes the larger memory, and immediately utilizes it for
additional call capacity. Included with this kit is an ESD wrist strap
to prevent damage to the SIMM and to the switch from electrostatic
emmisions.
Installation
Upgrade KIt
In order to help you, 3Com supplies all the tools necessary for the
upgrade in the installation upgrade kit. The installation upgrade kit
supplied with the 32MB SIMM contains the following items (see
Figure 1-1):

Safety
Precautions
Before working with any component in the CoreBuilder 7000
System, read and adhere to the following safety precautions.
ESD Safety Information
Electrostatic Discharge (ESD) can damage components on the system
module. ESD, which occurs when the module or a component is
improperly handled, can cause complete or intermittent failures.
CAUTION: To prevent ESD-related damage:
 Always wear the ESD wrist strap supplied, ensuring that the strap is
firmly secured to your wrist. The other end should be connected to a
grounded surface Connect the clip on the end of the wrist strap to a
grounding point on an anti-static table or to a grounded distribution
rack.
 Keep the 32MB Memory SIMM in its antistatic shielded bag until you
are ready to install it.
 When working with CoreBuilder 7000 components, always place the
component on the antistatic bag that it was shipped in.
