This appendix contains information on how to ensure that your NETBuilder II
configuration conforms with EMC requirements.
The NETBuilder II platform is modular. A complete system consists of a chassis, a
main processor module, and I/O modules. For a complete system to be
compliant, each of these components must comply with the rules described in
the sections that follow. Additionally, some combinations of I/O modules will not
meet EMC standards, as noted in the "Exceptions" section.
All NETBuilder II chassis accompanied by this guide are EMC-compliant.
Your system has the CE mark on the upper rear portion of the top cover of
the chassis.
Older versions of the CEC and I/O modules cannot be used in a system if
compliance is a requirement. The main processor module and all I/O modules
have been revised to meet these more stringent emissions standards. Compliant
main processor and I/O modules can be identified by the artwork on the I/O
panel face. All compliant modules bear the 3Com block logo on the front
panel, as shown here:
XXXXXX
®
Older, non-compliant NETBuilder II I/O modules are marked "3Com" and do not
have the 3Com block logo.
The following page, if present, lists specific configurations of I/O modules that
do not meet EMC requirements.
Each module package includes release notes with configuration exceptions as
well as other compliance guidelines. Replace page B-2 with the most current
version of these release notes, which are included with every module
3Com ships.
