ABOUT THIS GUIDE
PURPOSE This guide gives specific information on how to operate and use the
management functions of the switch.
AUDIENCE The guide is intended for use by network administrators who are
responsible for operating and maintaining network equipment;
consequently, it assumes a basic working knowledge of general switch
functions, the Internet Protocol (IP), and Simple Network Management
Protocol (SNMP).
CONVENTIONS The following conventions are used throughout this guide to show
information:
N OTE : Emphasizes important information or calls your attention to related
features or instructions.
C AUTION : Alerts you to a potential hazard that could cause loss of data, or
damage the system or equipment.
W ARNING : Alerts you to a potential hazard that could cause personal injury.
RELATED PUBLICATIONS The following publication details the hardware features of the switch,
including the physical and performance-related characteristics, and how to
install the switch:
The Installation Guide
Also, as part of the switch’s software, there is an online web-based help
that describes all management related features.
REVISION HISTORY This section summarizes the changes in each revision of this guide.
