Installing a Module

Safety Precautions

If you purchased a Switch 4005 starter kit that includes all the modules you
require, then you can skip this section. However, if you need to install one or more
modules, then read the cautions and instructions in this section before you begin.
When you handle components for a Switch 4005, be sure that you follow all
safety precautions. To avoid electric shocks, burns, or equipment damage, read
and follow these warnings:
WARNING: The Switch 4005 chassis and its components (such as modules) must
be installed, maintained, or replaced only by trained service personnel. This guide
assumes that the network administrator has a working knowledge of local area
network (LAN) operations. Furthermore, this guide assumes that the network
administrator has obtained appropriate technical training and experience to
perform tasks in service access areas of network equipment, to be aware of
electrical hazards that exist in performing these tasks, and to take steps that
minimize the danger to themselves or other persons. If you have questions on
installation tasks, contact your network supplier or 3Com technical support. See
Appendix A for contact information.
WARNING: Hazardous energy levels exist inside of the chassis. Use extreme
caution when you install, remove, or replace any module in the chassis. When the
system is powered on:
Never insert metal objects such as a screwdriver or a finger with jewelry into
I
open module slots.
Do not touch any connections within the chassis with your hands or fingers.

WARNING: To maintain proper cooling in the chassis and to maintain safety
compliance, make certain that a blank faceplate covers any empty module slot.
WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot be
used as standard traditional telephone sockets, or to connect the unit to a
traditional PBX or public telephone network. Only connect RJ-45 data connectors,
network telephony systems, or network telephones to these sockets. Either
shielded or unshielded data cables with shielded or unshielded jacks can be
connected to these data sockets.
AVERTISSEMENT: Points d'accès RJ-45. Ceux-ci sont protégés par des prises de
données. Ils ne peuvent pas être utilisés comme prises de téléphone
conventionnelles standard, ni pour la connection de l'unité à un réseau
téléphonique central privé ou public. Raccorder seulement connecteurs de
données RJ-45, systèmes de réseaux de téléphonie ou téléphones de réseaux à ces
prises. Il est possible de raccorder des câbles protégés ou non protégés avec des
jacks protégés ou non protégés à ces prises de données.
WARNHINWEIS: RJ-45-Porte. Diese Porte sind geschützte Datensteckdosen. Sie
dürfen weder wie normale traditionelle Telefonsteckdosen noch für die
Verbindung der Einheit mit einem traditionellem privatem oder öffentlichem
Telefonnetzwerk gebraucht werden. Nur RJ-45-Datenanscluße,
Telefonnetzsysteme or Netztelefone an diese Steckdosen anschließen. Entweder
geschützte oder ungeschützte Buchsen dürfen an diese Datensteckdosen
angeschlossen werden.
